‘Brainy, twisty, inventive’
– AJ Finn, The Woman In The Window

Published in the UK in August 2026 (Bloomsbury)

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?

Is it possible to scare someone to death? Jon Stock explains all in the Telegraph’s Culture section

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.’

The Sleep Room
by Jon Stock
(aka J.S.Monroe)

‘A beautifully researched, wildly unsettling study of a psychiatrist running amok’ – Sam Knight, author of The Premonitions Bureau

 

The Royal Waterloo Hospital, London in the 1960s. Six young women lie asleep on low beds. Day and night no longer exist, extinguished by a potent cocktail of antipsychotic, sedative and anti-depressant drugs. The women are taken from their beds by the nurses and given electroconvulsive therapy before being put to sleep again. All under the watchful eye of Dr William Sargant.

The Sleep Room is a chilling exposé of Sargant’s bizarre psychiatric treatments that were inflicted on hundreds of women with mental illness – among them the actor Celia Imrie. At the story’s centre is a sinister and charismatic doctor, who was a hugely influential figure in post-war British society – lauded by Robert Graves and Aldous Huxley as well regularly appearing on the BBC. When Sargant died in 1988, the obituaries were glowing.

But since then, women treated without their consent and with often horrific side-effects lasting decades have been campaigning to tell the truth about Sargant. Author Jon Stock tells these women’s stories as well delving into the murky history of Sargant’s links with MI5 and the CIA, both of which took a close interest in his disturbing efforts to reprogramme the human mind.

As compulsive as a thriller, The Sleep Room finally gets to the truth of a scandal at the heart of the British medical establishment. “Some people think I’m a marvellous doctor,” Sargant once said. “Others think I’m the work of the Devil.”
