You have a hook, a body, and an inciting question. What you need is a writer who can keep three suspects credible across 240 pages without losing the reader to a hole at chapter twelve.

Sub-genres we work in

The mystery & thriller categories with their own conventions.

Sub-genres each have their own structural rules, word-count norms, and reader expectations. We assign by sub-genre, not just by parent.

Sub-genre Cozy mystery

Sub-genre Police procedural

Sub-genre Legal thriller

Sub-genre Psychological thriller

Sub-genre Domestic suspense

Sub-genre Crime / noir

Sub-genre Spy thriller

Sub-genre Medical thriller

Genre conventions

The rules we will not break unless you ask.

Every category has conventions its readers expect. The right time to break them is on purpose, with eyes open. The wrong time is by accident.

Plot before prose. Outline survives a hostile-read pass before chapter one is drafted.
Suspect parity. Each viable suspect has motive, means, opportunity through at least chapter ten.
Reveal placement. The big reveal lands 80–88% through the book. Earlier reads as anticlimax; later loses readers.
Detective POV is the default; first-person works in domestic suspense; multi-POV works in police procedural.
Cliffhanger chapters where the genre expects them; resolution chapters where the genre demands them.

Case study

The Verdict Room

by Deborah Ngozi Okafor, Practicing trial attorney; first-time novelist ASIN B0DPRT2WLX

The brief: Deborah's manuscript was strong for 30,000 words and then stalled. She had two endings and could not decide between them. Both were the wrong ending for the book she had actually written in the first half.
The outcome: Self-published 73,000-word legal thriller. Earned out the editing investment in five months on Amazon. Three months post-launch, signed with an agent at Janklow & Nesbit for a two-book deal; Macmillan acquired North American rights for a 2026 hardback release.

Cozy vs hard mystery?

Different readers, different rules. Cozy stays out of forensic detail and on-page violence; the murder happens off-page. Hard mystery embraces both. The writer pairing changes based on which side you're on.

Will you outline before writing?

Always. For mystery and thriller specifically, the outline is a 10–20 page document with every reveal positioned, every suspect's alibi documented, and every plot hole flagged. We do not start prose until that document survives a hostile-read pass.

What if my mystery has a twist that's been done?

Most have. The question is whether the execution makes the twist feel new. We will tell you on the discovery call whether your twist is too close to a recent bestseller and recommend an angle.

Memoirs work when one specific reader feels seen. Ours work because we interview the author into the chapters that aren't on the LinkedIn page.
