The “timing and gothic atmosphere are second to none” in this classic mystery where “the suspense steadily builds . . . until the satisfying denouement” (Publishers Weekly).

From the moment nurse Sarah Keate arrives at the gloomy mansion of Adolph Federie, she senses trouble afoot, from the mysterious occupants of the house to the penetrating stare of a black cat named Genevieve. But Mr. Federie has just suffered a stroke and needs a live-in aid and Sarah is not one to shirk her duties.

When a murder occurs in the same room as her patient, Sarah starts investigating along with the help of a local police officer. But how will she sleep at night knowing she’s sharing a house with a killer?

An early title in the career of a crime writer whose many novels landed on bestseller lists for much of the twentieth century, While the Patient Slept is a creepy and atmospheric whodunit sure to please any fan of classic mysteries. It was included in the legendary Haycraft-Queen list of the greatest mystery novels of all time.
