Devices and Desires is a 1989 detective novel by English writer P. D. James, the eighth book of her Adam Dalgliesh series.

Commander Adam Dalgliesh, having published his second volume of poetry, retreats to the remote Larksoken headland where his recently deceased aunt, Jane Dalgliesh, has left him a converted windmill.

However, a psychopathic serial killer, known as the Norfolk Whistler, is on the loose and seems to have arrived at Larksoken when Dalgliesh finds the body of the nearby nuclear power plant's Acting Administrative Officer during an evening stroll on the beach.

In a 1990 book review for The New York Times, Judith Crist wrote "Her newest mystery, 'Devices and Desires,' is P. D. James at better than her best... She has not failed us, and she has exceeded herself.

"[1] A television version of the novel was produced for Britain's ITV network in 1991 starring Roy Marsden as Adam Dalgliesh.
