In this deathly funny and brilliantly original mystery from Adam Kay, former doctor and BAFTA-winning author of This is Going to Hurt, a chaotic young doctor might be the only one who can catch a killer targeting hospital officials—if his investigation doesn’t cost him his career first.

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 when another senior doctor dies, Eitan vows to uncover the truth himself.

But having recently returned to work after time off for his mental health, Eitan's personal file is far from spotless. Despite his budding relationship with Cole, a handsome hospital porter, and reluctant comradery with his office mate, Margaret-with-the-cats, Eitan is quickly in over his head. And as his investigation spirals into pandemonium, his colleagues begin to question his judgement. Could a killer really be roaming the halls? Or is Eitan making a catastrophic mistake?

This clever and fiendishly funny debut is filled with unforgettable 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.
