Verbs that pull the trigger: How to create momentum in crime and thriller writing

24/4/2026

1 Comment

 
Learn how to compress your thrillers and crime fiction writing with strong verbs that convey motion, emotion and pace.
Picture

What is a verb?

A verb is a word that describes an action or a state of being. For example:​
​
  • They ran down the alleyway
  • Ze sat on the bashed-up stool.
  • She loaded the rifle.
  • His hand trembled as he popped the pill.
  • ‘The kids are happier now that we’ve moved out here.’

Strong and weak verbs

There are different ways of classifying verbs from a grammatical point of view, but this article uses the terms ‘strong’ and ‘weak’ to describe stylistic impact.

Strong verbs
Strong verbs carry the action all by themselves without needing help from other words to make the sentence convey energy and momentum.

A precise, vivid verb can replace a string of modifiers. It makes a line faster and sharper, and can trigger a sense of immediacy, danger, tension or suspense in the reader.

Weak verbs
Weak verbs are vaguer or more generalized, and often rely on help from additional description to explain the action. They tend to slow the pace down.

There’s room for both
There’s no such thing as ‘wrong’ or ‘right’ when it comes to writing. Strong and weak verbs both have their place.

Instead, the writer can make a choice based on the mood they want to create in the scene and how they want the reader to feel in that moment.

A comparison of strong and weak verbs

​Take a look at the following comparative examples of phrases. They show how a carefully placed strong verb can show rather than tell us something. For example:
  • She tried to pull open the drawer but it wouldn’t give.
  • She yanked at the drawer but it wouldn’t give.
In the first sentence, there’s a verbal phrase in play – ‘tried to pull open’. Those four words create a distance between the character and what they’re doing. We focus on the ‘trying’ rather than on the connection between the character’s hands and the drawer. The pace feels gentler, slower, less immediate.
​
By replacing that verbal phrase with a single strong verb – ‘yanked’ – the action is more immediate. But there’s emotion being conveyed in that action too:
  • urgency – it’s being done quickly and without hesitation
  • forcefulness – it’s movement that lacks delicacy or care
And those emotional undercurrents imply that the character is under pressure, perhaps feeling frustrated, angry or fearful (depending on the scene’s context). In other words, the stronger verb shows the character’s effort through action rather than explanation.

Create immediacy by adjusting filler verbs

Look out for filler verbs in your crime and thriller writing. These act more like padding than action, and sit in the sentence without contributing much.

Common examples include: was, were, seemed, appeared, began, trying and started. These constructions add extra words without adding tension.

Writers can create momentum in action scenes by making just small alterations. Here, we’re not talking about changing the verb to a different one, but modifying what we’ve got.
​
Take a look at these examples:
  • He was running down the alley, looking for shadow, a nook, anything that would provide cover. 
  • He ran down the alley, looking for shadow, a nook, anything that would provide cover.
  • She began to walk towards the cafe, head down, shoulders hunched.
  • She walked towards the cafe, head down, shoulders hunched.
  • He put his foot down, and the engine started to roar.
  • He put his foot down, and the engine roared.
​In each of the three pairs above, removal of the filler verb in favour of a tighter revision makes the action feel as if it’s happening now. For the reader, that’s a more immersive experience.

Create impact by interrogating adverbs

Sometimes a writer will use adverbs to intensify the emotion or tension in a sentence.
Adverbs are words that describe or modify verbs (in the same way that adjectives describe or modify nouns).
​
In these next examples, most of the verbs are weak, and it’s the adverb that’s doing the heavy lifting.
  • She stood up fast. (Verb is weak. Adverb conveys speed.)
  • Xe said quietly in Jon’s ear. (Verb is weak. Adverb conveys volume.)
  • The engine roared loudly. (Verb is strong. Adverb repeats volume.)
  • A siren wailed. Doors opened and closed with a bang. (First verb is strong. Second and third verbs are weak. Adverbial conveys sound.)
  • She looked quickly over her shoulder. (Verb is weak. Adverb conveys speed.)
  • They made their way confidently out of the building. (Verbal phrase is weak. Adverb conveys attitude.)
I’d never suggest obliterating every single adverb or adverbial phrase from a piece of prose – regardless of what genre the author’s writing in – but I do think robust editing requires us to consider whether those adverbs are creating momentum and energy.

This is particularly important in dramatic scenes, of which there are often plenty in crime fiction, mysteries and thrillers. We want the reader in the moment with the perspective character’s movement, not fighting with the words that describe it.

Since the verb is where the action actually happens, it makes sense to interrogate whether readers are being distracted from it.

In the examples above, the writer has the opportunity to consider whether a stronger verb might offer precision that shows what the adverb is telling – which means they can ditch the adverb.
​
Here’s what that revision might look like when we use stronger verbs that combine movement and emotion:
  • She jumped up. (Verb conveys speed and urgency.)
  • Xe whispered in Jon’s ear. (Verb conveys volume.)
  • The engine roared. (Verb alone conveys volume.)
  • A siren wailed. Doors slammed. (Verb conveys immediacy and aggression.)
  • She glanced over her shoulder. (Verb conveys fleeting movement.)
  • They strode out of the building. (Verb conveys confidence.)
Now the sentences are tighter and more engaging. 

Making movement thrilling with strong verbs

Crime fiction and thrillers rely on movement – there might be pursuits, fights, discoveries and escapes. And in all those cases, verbs need to carry that movement in a way that captures emotion.

Instead of weaker neutral verbs like went, looked or moved, think about whether verbs that imply force, violence, emotional state or speed might be more effective.
​
Compare the following:
  • He went across the room. (Weak generalised verb.)
  • He crossed the room. (More precise verb.)
  • He stormed across the room. (Even more precise and conveying anger.)
  • She looked through the papers. (Weak generalised verb.)
  • She combed through the papers. (More precise verb that conveys purpose.)
  • She rifled through the papers. (Precise but more intense and conveys urgency and aggression.)
  • She hit the attacker in the face. (Weak generalized verb.)
  • She punched the attacker in the face. (Stronger verb conveying more powerful blow.)
  • She slammed her fist into the attacker’s face. (Even higher energy and violence.)
Careful choices allow writers (or their editors) to capture an entire mood in a single verb.

Practise control with a verb-intensity ladder

One way to hone your verb-choosing skills is to build intensity ladders. These help you see how different words, which mean a similar thing, affect the emotional intensity and urgency of a scene.

To be clear, this isn’t about ranking verbs in order of what’s right or wrong or good or bad, but about controlling the impact you want to have on the reader.
​
Here’s an example where the intensity level moves from calm to extreme. The action we’re considering involves the opening of a door.
Door-opening intensity ladder
  • Intensity level 1 (lowest): ​She opened the door. (Emotional tone: neutral)
  • Intensity level 2: She pushed the door open. (Emotional tone: deliberate)
  • Intensity level 3: She eased the door open. (Emotional tone: stealth)
  • Intensity level 4: She pulled the door open. (Emotional tone: purposeful)
  • Intensity level 5: She jerked the door open. (Emotional tone: startled)
  • Intensity level 6: She yanked the door open. (Emotional tone: urgent)
  • Intensity level 7: She wrenched the door open. (Emotional tone: violent)
  • Intensity level 8 (most extreme): She kicked the door open. (Emotional tone: explosive)
Here’s another example. This time the action involves the act of moving away from a situation.
Moving-away intensity ladder
  • Intensity level 1 (lowest): He walked down the alley. (Emotional tone: relaxed)
  • Intensity level 2: He strode down the alley. (Emotional tone: purposeful)
  • Intensity level 3: He hurried down the alley. (Emotional tone: milder urgency)
  • Intensity level 4: He rushed down the alley. (Emotional tone: more urgency)
  • Intensity level 5: He ran down the alley. (Emotional tone: active)
  • Intensity level 6: He sprinted down the alley. (Emotional tone: maximum effort)
  • Intensity level 7: He bolted down the alley. (Emotional tone: sudden panic)
  • Intensity level 8 (most extreme): He fled down the alley. (Emotional tone: desperation)
When you pick verbs that are lower in intensity, the tension will be quieter and the pace slower. When you choose verbs that are higher in intensity, the tension will be more acute and the pace faster.
​
What works best in any particular scene will depend on the context, but the point is that just one verb helps you turn up or turn down the dial and control motion, emotion and pace.

A tip for editing verbs

If you’re a writer who’s self-editing, or a professional editor providing support for an author, try this exercise. Ask yourself:
  • What’s the mood of the scene – relaxed, contemplative, risky, dangerous?
  • Which verbs or verbal phrases are conveying the character’s actions or state of being?
  • Do those verbs convey motion, emotion and pace?
  • Are they precise (ie single words) or is there padding (eg adverbs and filler verbs)?
  • Would a different stronger verb (either low or high intensity) more effectively capture appropriate motion, emotion and pace?

Summing up

When looking at word choices in crime fiction and thriller writing, think about which verbs act as controlled triggers for motion, emotion and pace.

The power lies in choosing something that already carries the meaning, because then there’s no need to add adverbials and filler.

Making Tax Digital (MTD): Using a bridging service

17/4/2026

3 Comments

 
If you’re a UK-based freelance editor or proofreader who still hasn’t decided how to deal with Making Tax Digital, here’s how one of your colleagues solved the problem by using a bridging service.
Picture

In this post ...

  • What is Making Tax Digital?
  • When does MTD start?
  • How often do we have to file with MTD?
  • What is a bridging service?
  • Why I chose 123sheets
  • Preparation tips for using bridging services

​A caveat

I’m a professional editorial business owner, not a tax expert. The information I’ve provided below is what I’ve picked up on my MTD journey, and I've done my best to ensure it’s correct at the time of writing (April 2026).
​
If you’re in any doubt about your own tax position, speak to an accountant. There’s lots of information at GOV.UK too.

What is Making Tax Digital?

Making Tax Digital (MTD) is the UK government’s attempt to drag tax reporting out of spreadsheets and shoeboxes and into the twenty-first century.

MTD means we, as UK-based sole traders, have to keep digital records and file updates using compatible software several times a year. The idea is to make things more accurate, reduce errors and cut down on last-minute annual panics.

Personally, I wasn’t panicked by the traditional system. And I was more than happy managing my finances in a spreadsheet … And with submitting my tax return via HM Revenue & Customs (HMRC)’s online self-assessment gateway … And with doing that just once a year … And at zero cost to me. 
​
I’m starting to sound like a grouch, but I promise I’ll be sharing the low-cost solution I found below!

When does MTD start?

MTD is already up and running for self-employed people who are earning over a particular income threshold. Those who don’t meet that threshold will have a year’s grace. 
​
Still, you might qualify to join the scheme early, and that could be a good option for anyone wanting to get to grips with it ahead of time so there’s no last-minute rush.

How often do we have to file with MTD?

With MTD we have to submit what HMRC calls quarterly updates.

The key thing we all need to bear in mind is that these updates are cumulative. We’re not doing four separate mini-returns. Think of it as a rolling picture that builds across the year.

​If your financial year starts on 6 April, the deadlines will be as follows:

  • Q1 (6 Apr–5 Jul): due 7 August
  • Q1–Q2 (6 Apr–5 Oct): due 7 November
  • Q1–Q3 (6 Apr–5 Jan): due 7 February
  • Q1–Q4 (6 Apr–5 Apr): due 7 May

At the end of the year, there's an End of Period Statement (EOPS) that, says HMRC, ‘confirms the figures for the full year and allows accounting adjustments such as capital allowances or basis period adjustments’.

Then there’s the final declaration (which replaces the self-assessment tax return), and that’s due by 31 January following the end of the tax year.
​
What all this means is that there are way more touchpoints but no change to when your financial year starts or when the final bill gets sorted.

What is a bridging service?

Given that I was already perfectly happy with using a spreadsheet, then submitting my tax returns digitally, and not spending a bean in the process, I absolutely didn’t want to fork out for an accountant four times a year or expensive software.

For that reason, last year I started exploring affordable bridging services.

A bridging service for MTD acts a bit like a translator between your existing records and HMRC’s systems.

If, like me, you’re still recording your income and expenses in spreadsheets, those spreadsheets aren’t set up to talk directly to HMRC. That’s where bridging software comes in.

It bridges the gap by taking the figures from your spreadsheet and submitting them to HMRC in the right digital format. And that allows you to stay compliant with MTD without ditching the way you already work.

In practice, it means:
​
  • you keep your records in Excel (or similar)
  • the bridging tool links to your spreadsheet
  • it pulls through the relevant numbers
  • then sends them to HMRC as part of your MTD submission.

​So, if you’re happy with spreadsheets, like I am, and don’t want to move to full accounting services just yet (or ever!), a bridging service can be a handy halfway house.

Why I chose 123sheets

My research led me to sign up with  123sheets. Here's why I chose them:

  • They’re on HMRC’s list of compatible providers.
  • They provide a downloadable, ready-to-go, MTD-compliant worksheet, meaning I can link the relevant cells in my Excel spreadsheet to the appropriate cells in their worksheet. Then it’s simply a case of logging in to their site, uploading the quarterly update and clicking a ‘File’ button.
  • It’s cheap at chips – less than £45 (including VAT) a year, and there’s a 50% discount on your first year!
  • The dashboard is dead easy to use – like it was made for people (like me) who can think of a thousand other things they’d rather do that file a tax return.
  • There are videos to guide you in the event you get stuck (though you probably won’t).

To be clear, there’s no financial benefit for me by telling you about this company. I’m simply sharing the choice I made with you, and the reasons behind it, so that anyone who’s feeling a bit flummoxed, and who’s a spreadsheet user like me, might feel a bit more reassured that there are user-friendly options out there. There’ll be plenty of other UK-based professionals in our industry who've already opted (or will opt) for other methods with different providers.

Preparation tips for using bridging services

Here are some tips to help you prepare if you decide to go down the bridging-software route.

Choose a good-fit provider
  • Look for one that makes you feel like it’s easing the load rather asking you to climb yet another hill.
  • Select one that’s on HMRC’s list of compatibles.
  • Check that you understand how the software works well ahead of time, and that your records system works with theirs.

Prep your spreadsheet

  • Make sure your accounts spreadsheet is recording quarterly totals for income and expenses.
  • It’ll save you time if you add a sheet that captures the cumulative totals: Q1, Q1–Q2, Q1–Q3 and Q1–Q4.

Sign up for MTD

  • Any bridging service you choose can’t connect your records with HMRC until you’ve authorised them to do so. For that to work, you need to have signed up for MTD.
  • To sign up for MTD in a particular year, you need to have filed your previous year’s tax return.

Shift your mindset

  • As soon as your income falls within MTD’s scope, you’ll need to be ready, so start prepping before you need to so that you have a bit of breathing space.
  • Set up a routine so that you’re recording income and expenses on a regular basis (eg monthly or even weekly). That way, when a submission deadline rolls around, you’re basically already done.

Wrapping up

Change can be hard for busy business owners, especially when we can’t immediately see how the outcomes benefit us. That’s how MTD is making a lot of self-employed people feel.

​However, by getting organised, and selecting tools and providers who can help us keep things ticking over smoothly, I'm confident that MTD can be just another a bit of admin rather than a headache.

7 types of thriller opening lines (with examples from bestselling novels)

9/4/2026

1 Comment

 
Explore seven effective types of thriller opening lines, and how published novelists are using them to convince their audiences to keep on reading.
Picture

In this article

  • The recognizable patterns in thriller opening lines
  • First-line focus on a pursuit
  • First-line focus on psychological mindset
  • First-line focus on a shocking statement
  • First-line focus on a crime or transgression
  • First-line focus on the environment
  • First-line focus on foreboding

The recognizable patterns in thriller opening lines

The opening line of a thriller has a difficult job. In a single sentence it must capture attention and convince readers that the story is worth their time.

While great first lines vary in style, there are some recognizable patterns. Understanding these can help writers craft first sentences that hook readers immediately.
​
Below we’ll look at seven types of thriller opening lines – each illustrated with examples from published novels – and examine why they work and what writers can learn from them.

What these opening lines have in common

Despite their differences, superb thriller first lines usually share several notable qualities:
​
  • Stakes: suggests that a character’s in danger or facing a threatening predicament
  • Curiosity: creates intrigue whereby readers have at least one question they want answered
  • Tension or conflict: hints that something is wrong
  • Voice: Establishes a tone that makes us interested or invested in the narrator
  • Momentum:  Gives the reader a reason to keep moving through the prose.

1. First-line focus on a pursuit

Some thrillers begin with motion already underway: someone is chasing, escaping or searching.

Example: The Gunslinger, Stephen King (Hodder Paperback edition, 2003)
Picture
​The man in black fled across the desert, and the gunslinger followed.
​Why it works
Readers are thrust straight into the middle of a high-stakes chase. In a single line, we sense the tension: one character fleeing, another in pursuit. The sentence immediately conveys motion, suspense and intrigue, and prompts questions like: Who are these figures and what is at stake?
​
NOTABLE QUALITIES: Curiosity | Tension or conflict | Momentum

Lesson for writers
Movement signals urgency. Starting with that signals that the story is already underway and that the reader has arrived in the middle of something important.

2. First-line focus on psychological mindset

These first lines hook readers by revealing a shocking fact, personal truth or secret. They often feel rather confessional create powerful psychological intrigue because they invite readers into a character’s headspace.

Example 1: Dark Places, Gillian Flynn (Phoenix edition, 2010)
Picture
I have a meanness inside me, real as an organ.
Why it works
The opening plunges readers into the narrator’s psyche, exposing an unsettling inner darkness before any plot events occur. This early insight builds psychological tension, making us question the narrator’s reliability and wonder how their mindset will shape the story.

NOTABLE QUALITIES: ​Curiosity | Tension or conflict | Voice

Example 2: The Martian, Andy Weir (Del Rey edition, 2014)
Picture
​​I’m pretty much fucked.
Why it works
In those first four words, the narrator signals that disaster has struck. The candid, no-nonsense tone generates immediate suspense, encouraging readers to ask: What has happened? How will the character cope?

NOTABLE QUALITIES: Stakes | Curiosity | Tension or conflict | Voice

​Lesson for writers
Confessional first lines can draw readers directly into a character’s predicament or provide striking psychological insight in just a few words. These two examples are also good reminders that a strong narrative voice can be just as compelling as action or a crime.

3. First-line focus on a shocking statement

A bold or disturbing statement can grab readers immediately, forcing them to confront moral tension or danger.

Example: I Will Find You, Harlan Coben (Penguin edition, 2023)
Picture
I am serving the fifth year of a life sentence for murdering my own child.
Why it works
A single, startling sentence conveys both shock and intrigue. It instantly raises questions and emotional stakes. Readers want to understand the circumstances that led the narrator, speaking directly to us, to this moment.

NOTABLE QUALITIES: Stakes | Curiosity | Tension or conflict | Voice | Momentum
​

Lesson for writers
A single unexpected statement can create a powerful hook if it suggests a deeper story.

5. First-line focus on a crime or transgression

Some thrillers’ opening lines reveal a crime or transgression that has already occurred or is in progress.

Example: Paradise, Toni Morrison (Vintage edition, 1999)
Picture
​They shoot the white girl first.
Why it works
The sentence is shocking, violent and blunt, though we’re not given any context. That ambiguity forces readers to ask questions: Who are ‘they’? Who are the other girls that it’s implied are also going to be shot? Why have these girls been targeted?

NOTABLE QUALITIES: Curiosity | Tension or conflict | Momentum
​

Lesson for writers
Introducing the crime early tells readers exactly what kind of story they’re entering.

6. First-line focus on the environment 

Some thrillers begin by establishing an unsettling atmosphere.

Example 1: Neuromancer, William Gibson (Gateway edition, 2016)
Picture
The sky above the port was the colour of television, tuned to a dead channel.
Why it works
This line uses a striking image to establish a bleak, dystopian environment. It signals that the world of the story may feel strange or unsettling.

NOTABLE QUALITIES: Tension or conflict | Voice

Example 2: The Day of the Jackal, Frederick Forsyth (Arrow edition, 2011)
Picture
​It is cold at six-forty in the morning of a March day in Paris, and seems even colder when a man is about to be executed by firing squad.
Why it works
This opening sentence starts with information about the weather and the time. It could have been dull, but the author uses it as an artful anchor for the life‑or‑death clause that follows. The stark, cold setting mirrors the flat, cold voice, as if the narrator has accepted the inevitability of the execution.

NOTABLE QUALITIES: Stakes | Tension or conflict | Voice
​

Lesson for writers
A vivid or unusual image can establish tone while creating curiosity about the setting. And environmental information can be highly effective as long as it’s used to amplify a character’s mood.

7. First-line focus on foreboding

This type of opening signals that something terrible has already happened, or is about to happen.

Example 1: Everybody Knows, Jordan Harper (Faber & Faber edition, 2023)
Picture
​Los Angeles burns. 
Why it works
In just three stark words, this first line establishes a vivid, ominous setting that suggests chaos and danger. Something catastrophic is happening in a familiar city, and readers want to know what caused it and what the consequences will be.

NOTABLE ​QUALITIES: Stakes | Curiosity | Tension or conflict | Momentum

Example 2: Gone Before Goodbye, Harlan Coben and Reese Witherspoon (Penguin, 2026)​
Picture
​I don’t hear the scream.
Why it works
In just five words, this line creates immediate tension. By emphasizing what the narrator doesn’t hear, it heightens the sense of unseen danger. The absence of sound signals that something is amiss, prompting readers to ask: What’s happening, and what threat lurks nearby?

NOTABLE ​QUALITIES: Curiosity | Tension or conflict | Momentum

​Lesson for writers
Opening lines that imply catastrophe, danger or abnormality can be incredibly effective. By hinting that something is wrong, rather than explaining it immediately,  activate the reader’s curiosity and tension, and compel them to keep going.

Summing up

A thriller’s first line doesn’t have to feature explosions or violence. What matters is that it avoids the mundane.

That means encouraging questions and making the reader feel something – for example shock, surprise, disgust, fear, confusion – so that they want to continue beyond the opening sentence and into the rest of the story.

10 weak first lines in mysteries and thrillers (and how to fix them)

2/4/2026

Explore 10 weak thriller opening lines and learn how to turn them into compelling hooks that grab the reader, set the tone and hint at something that piques their curiosity.
Picture

The weight carried by the opening line

The opening line of a mystery or thriller carries an enormous amount of weight. In just a few words, it has to hook the reader, set the tone and indicate a problem or predicament that will pique the reader’s interest.

Manuscripts with first lines that feature routine description, backstory or everyday dialogue can feel flat rather than gripping.

In this article, we’ll look at 10 examples of weak first lines, explain why they don’t work, and show how small revisions can turn them into compelling hooks.

If you’re writing a mystery, crime novel or psychological thriller, these examples will help you craft a first sentence that immediately grabs readers … and keeps them wanting to read.

Example 1: Generic description

​Weak first line
  • It was a cold and rainy night in the city.
Why it’s ineffective
The description is generic and objective. There’s no character, no tension and no intrigue.

Suggested improvement
  • The rain washed the blood toward the storm drain before anyone noticed the body.
Why the revision helps
The objectivity remains, but now the reader is immediately introduced to a crime – one that makes us ask questions: Whose body? How did they die? And by whose hand?

Example 2: Routine activity

Weak first line
  • Detective Harris sat down at his desk and found the murder weapon waiting for him. ​
Why it’s ineffective
While there’s a human being involved in this line, Harris’s actions are mundane. The sentence is front loaded with activity related to where he sits. Even though a murder weapon is mentioned, that’s not particularly interesting given the detective’s job.
There’s no reason for us to do anything with this line than skim over it.

Suggested improvement
  • Detective Harris stared at the murder weapon – handcrafted blade, premium steel, artisan finish, and identical to the one his son had bought only four days earlier.
Why the revision helps
Now there’s a conundrum for us to consider – the familiarity of the weapon. This creates a pressure point for Harris, and a mystery that readers want an explanation for.

Example 3: Focus on backstory 

Weak first line
  • Martha had always loved living in the quiet town of Hemsby.
Why it’s ineffective
The focus here is on the past rather than the present, and that backstory is generalised and mundane.

Suggested improvement
  • The first dead body in Hemsby appeared three houses down from Martha’s front door.
​Why the revision helps
Now there’s momentum. The word ‘first’ introduces foreshadowing – readers will assume that there’s more than one dead body. The mention of proximity to a named character forces us to wonder about her role: Is Martha a potential victim, too, or is she a transgressor?  

Example 4: No intrigue

Weak first line
  • John woke up early that morning and checked the time.
Why it’s ineffective
So what? the reader might think. Waking up early in the morning is not intriguing. It’s commonplace.

Suggested improvement
  • John woke to the sound of someone unlocking his front door.
Why the revision helps
Now there’s immediate tension. The word ‘someone’ implies that another person entering the house is unexpected. And yet ‘unlocking’ suggests they have a key. That leads to readers asking questions: Who’s in his space? Should they be there? Is John in danger?

Example 5: Vague observation

Weak first line
  • The small town felt peaceful that morning.
Why it’s ineffective
This line tells us readers nothing about why they should care about this peaceful place, nor why they should carry on reading about it.
​
Suggested improvement
  • The town felt peaceful – until the police divers pulled the suitcase out of the lake.
Why the revision helps
The revised line is still told from an objective perspective, and the peacefulness has been left intact. However, that information is now sharply juxtaposed with a shocking discovery. Using contrast helps to create surprise and intrigue.

Example 6: Dull dialogue

Weak first line
  • “Morning,” Tom said as he poured coffee.
Why it’s ineffective
This is mundane speech – the kind of thing millions of people say to each other at times and spaces across the entire planet. It won’t compel a reader to continue.
​
Suggested improvement
  • “I didn’t do it,” Tom said, though in truth he couldn’t be sure.
Why the revision helps
Now we have an instant mystery. Readers will wonder what the ‘it’ is that Tom didn’t do, and they’ll want to know why he’s doubting himself. 

Example 7: Tensionless thoughts

Weak first line
  • Emily drove to work, thinking about her busy day.
Why it’s ineffective
There’s no pressure point in this character thought. It’s skimmable information.
​
Suggested improvement
  • Emily was halfway to work when the radio announced that her husband had been murdered.
Why the revision helps
Now we understand the possible emotional stakes in play. Maybe this information comes as a horrific shock to Emily. Or maybe it will be revealed that she killed him. It actually doesn’t matter. All that’s important is that this is personal, and the reader will be invested in understanding why. 

Example 8: Boring environment

Weak first line
  • The office building is large and modern.
Why it’s ineffective
The description feels flat and doesn’t convey any personality or tension.
​
Suggested improvement
  • ​The modern office block has thirty floors, but I’ll need only one to end Xavier Flint’s life.
Why the revision helps
Now we have an anonymous narrator with a clear agenda. While the motive is as yet unclear, which creates suspense, the tone is distinctly menacing. Readers will be wondering who this character is and what Flint’s done to evoke such anger.

Example 9: Flat impact

Weak first line
  • The police station is bustling when the missing girl walks through the door.
Why it’s ineffective
This at least introduces an interesting premise – that of the return of a missing person. However, it feels a little flat and lacks impact.
​
Suggested improvement
  • Sally Flowers has been missing for eleven years, three months and two days – and she’s just walked through the door.
Why the revision helps
In the revised version, the missing person has a name. And by leading with punchy description of how long Flowers has been missing for, the follow-up clause about her unexpected return creates shock and intrigue.

Example 10: No threat

Weak first line
  • You take an envelope from the mailbox, open it, and remove a photograph.
Why it’s ineffective
While the use of a second-person narrative hints at voyeurism, there’s nothing in that line that indicates anything’s out of whack.
​
Suggested improvement
  • The envelope you’ve taken from the mailbox contains a photograph – of you last night, sleeping.
Why the revision helps
The expository information about the mailbox, envelope and photograph are still there, as is the voyeuristic narration. However, by giving readers a small nudge about what’s in that image, there’s an imminent sense of threat.

Summing up

A great opening line to any thriller or mystery usually does at least one of these things:

  • Stakes: suggests that a character’s in danger or facing a threatening predicament
  • Curiosity: creates intrigue whereby readers have at least one question they want answered
  • Tension or conflict: hints that something is wrong
  • Voice: Establishes a tone that makes us interested or invested in the narrator
  • Momentum:  Gives the reader a reason to keep moving through the prose.

If these aren't evident in your first line, it’s worth revisiting.
