This is a short book comprising a series of elegantly written, inter-related essays about aspects of detective fiction by one of the best writers in this genre. The book will appeal to those who read a lot of detective fiction and will recognize many of the authors and books with pleasure as she reminds us of the books we've read and enjoyed. She has read and re-read a prodigious number of books in this category in her long life and it's interesting to learn what has influenced her own work and also about her views on authors past and present, though there is scant allusion to the authors of modern detective fiction such as Colin Dexter, Ian Rankin, Peter Lovesey or Ruth Rendell, which may reflect PD James's acknowledged reluctance to act as a reviewer/critic of her contemporaries.
Talking about Detective Fiction starts with an essay about the birth of this genre and the importance of Conon Doyle in making this kind of book popular. Much of the book concentrates on what she terms the "Golden Age" of detective fiction and the writers Agatha Christie, Dorothy L. Sayers, Margery Allingham and Ngaio Marsh figure largely. The American Golden Age also merits a chapter about the more gritty-style of Dashell Hammett and Ryamond Chandler. One of the later chapters touches on why PD James started to write detective fiction and a little about her approach to writing.
This is not an in-depth analysis of detective fiction: more a sampler of what's available, mainly from the past, and how these earlier books reflected the society of the time and influenced later writers. I enjoyed this book as not only did it remind me of books I'd read it also referred to authors from the past that I haven't read and might try.
