THE PSYCHIATRIST claims he can predict when people will die and has been using his skills with chilling accuracy.

THE PATIENTS trust their shrink. They believe him when he tells them their date and the predictions have always come true.

THE DETECTIVE is shaken when a man shoots himself after announcing it’s his ‘death day’. On his body, DI Silas Hart finds an hourglass, catapulting him back to two suspicious deaths that have haunted him for years.

When the psychiatrist turns his sights on Hart, the countdown to his own death day begins.

Will he survive? Or is there no escaping fate?

AJ Finn writes:

‘His Final Patient is brainy, twisty, inventive… and, remarkably, grounded in research at once fascinating and horrifying. It is, in other words, a JS Monroe thriller. Monroe writes thrillers for grown-ups: readers who admire sharp writing, readers who savor complex characters – characters like Silas Hart, one of the most appealing sleuths in contemporary crime fiction. The Hart novels are absorbing police procedurals that double as high-tension psychological thrillers (fans of Lisa Jewell, ready those nerves for jangling); but above all, they’re mind-meddling, sleep-defying stories, the sort that remind you what real suspense feels like.’
