DR. GOOD

Psychological Thriller

Lyra Beckett built a life that looks exactly the way a life is supposed to look. The right house on the right street in a town that loves her husband. Twelve years of charity committees and dinner parties and being the woman beside the man everyone trusts with their lives. She was a nurse once — before Julian, before Aldenmere, before she learned to take up less space. She was good at it. She still is.

Then a patient dies after a routine surgery. The hospital opens a review. The review closes. Nothing to see here.

Lyra has been looking at the numbers. And the numbers don’t quite add up.

Before she can talk herself out of it — before she can decide she’s tired and paranoid and imagining things the way her husband sometimes gently suggests she does — there are patient files that run fourteen weeks of recovery for a surgery that should take four, public data that maps into a shape no one was supposed to notice, a box in the bottom drawer of his filing cabinet behind a folder marked INSURANCE, and eleven years of private notes in her husband’s handwriting covering patients he was monitoring long after any clinical reason existed. His notes are precise and warm and include supplement recommendations and mood observations and a column, in some entries, labeled compliance.

The last folder in the box has her name on it.

The first entry is dated three months after she stopped working. Three months after she became his wife instead of a nurse. The entry reads: L. recovering well from minor procedure. Maintaining supplement protocol. Mood: stable. Compliance: complete.

She has been his most continuous patient for twelve years. She just didn’t know it.

Running alongside Lyra’s investigation — in a different voice, at a different register — is Danni Roe, 31, a grocery store manager who had an appendectomy five years ago and has never fully recovered. Her chapters are testimony, addressed to an unnamed investigator, flat and plain and devastating. She doesn’t know Lyra exists. She is building the same case from the other end.

Lyra has been performing the perfect life. Danni has been performing fine. The man between them has been performing good.

A razor-sharp domestic thriller for readers who already know that the scariest thing in a marriage isn’t a secret — it’s a system. The kind of book you read with the lights on and finish at 2am thinking about every time someone told you that you were imagining it.

WHY THIS WILL SELL

→ The psychological and domestic thriller market generates $2.6M/month in author royalties (K-Lytics, March 2026) — up +17% year-over-year. “Domestic thriller” is the fastest-rising search term in the category on Google Trends right now.

→ This trope stack is built from the category’s top performers. The doctor/medical/surgeon archetype scores a competition index of 100 — the single highest male character archetype in the 2026 K-Lytics report. The husband trope appears in 32% of the top 100. Perfect world/perfect family in 50%. Dr. Good sits at the intersection of all three.

→ The lie/lying trope (index 81, new and rising) validates the slow-reveal structure. Readers are actively seeking the information-drip architecture this book is built on — a revelation every few chapters, the pattern only visible in aggregate.

→ Medical specificity is a genuine white space in the category. The hospital setting, clinical detail, and “everyone trusts him” community framing give this book a texture that purely domestic titles can’t replicate — and no existing Plot & Prompt package occupies this lane.

→ The dual POV architecture drives KU page reads. The Lyra/Danni structure — present-tense investigation interspersed with retrospective testimony — creates compulsive forward momentum that produces the high page-read counts KU rewards.

→ Top 20 bestsellers in this category average ~782 copies/day. 100% are enrolled in Kindle Unlimited. This package is built for that market: KU-optimized, $3.99–$4.99 launch pricing, short punchy chapters matching current bestseller page-length trends.
