P. D. James brings a lifetime of reading and writing crime fiction to bear on this personal history of the genre, from the birth of the detective story, through Wilkie Collins and Conan Doyle, to the golden age of crime and the rise of Agatha Christie, Dorothy L. Sayers, Ngaio Marsh and Margery Allingham. There is a chapter on great American crime writers such as Raymond Chandler and Dashiel Hammett, and P. D. James also discusses many of her favourite detectives, from Sherlock Holmes to Kurt Wallender.
