A Particularly Nasty Case: The Fastest-Selling Debut Thriller of 2025 by Adam Kay

A chaotic young doctor might be the only person who can catch a killer in this "hilarious, macabre, and heartrending" (Lucy Foley) debut mystery from Adam Kay, former doctor and BAFTA-winning author of This is Going to Hurt.

“A thrilling, twisting mystery. . . . Impossibly funny but also deeply moving and often heartbreaking.” ― Chris Whitaker, New York Times bestselling author of All the Colors of the Dark

When his toxic medical director dies of a heart attack, fellow doctor Eitan Rose smells foul play. Nobody else does, though, including some quite crucial players like the police and the medical examiner. So Eitan vows to uncover the truth himself.

But Eitan's own past and reputation are far from spotless, despite his budding relationship with Cole, a handsome hospital porter, and reluctant camaraderie with his office mate, Margaret-with-the-cats. As his colleagues become increasingly concerned about his mental health, Eitan's investigation spirals out of control. Could a killer really be stalking the wards? Or is Eitan making a catastrophic mistake?

For lovers of Listen for the Lie and My Sister, the Serial Killer, this fiendishly clever and deathly funny debut is filled with acerbic wit, lovable characters, and plenty of twists—alongside texts, transcripts, medical reports, and all the evidence you’ll need to help solve this particularly nasty case.
