The year is 1999. Returning to practice after a suspension for stealing opioids, a young Scottish doctor takes the only job he can find: a post as a senior house officer in the struggling east London hospital of St Luke's.

Amid the maelstrom of sick patients, over-worked staff and underfunded wards a darker secret soon declares itself: too many patients are dying.

Which of the medical professionals our protagonist has encountered is behind the murders? And can our unnamed narrator's version of the events be trusted?

'A delightful read. The serial killer plotline is an added bonus. I loved it' Kathy Reichs, the #1 New York Times bestseller
