The Seventh Patient

Japan’s National Bestseller. A manga and a screen adaptation were released based on the book.

A tight, survival thriller inside the walls of a former psychiatric hospital.

A tense game with time from the acclaimed author of medical thrillers.

When an armed criminal takes over the hospital, doctors and nurses can only hope he won’t start killing. They have to make it to morning—and then, he says, he’ll leave on his own. But not everyone will live to see dawn…

Going on night duty, surgeon Hayamizu Sugo expected a quiet shift and a few hours of sleep. But he’s awakened by a sound that suspiciously resembles a gunshot… Coming downstairs to check, Sugo sees a nightmare: two terrified nurses are being held at gunpoint by a masked clown, and at his feet lies a girl bleeding out.

Seven hours until rescue in a locked hospital.

Under Sugo’s revolver, he is forced to operate—but “the clown” has no intention of disappearing. He locks the staff together with the bedridden patients and sets a single condition: if everyone gets through the night quietly, no one will be harmed.

One secret that could destroy everything.

But with each passing hour, there’s less and less sense in the captor’s actions. It’s too much like this hospital was chosen for a reason. And it’s too much like someone besides him is not interested in the police arriving. Could there be another criminal hiding behind the clinic’s walls?
