Winner of the 2016 EDGAR, AGATHA, MACAVITY and H.R.F.KEATING crime writing awards, this real-life detective story investigates how Agatha Christie and colleagues in a mysterious literary club transformed crime fiction. Detective stories of the Twenties and Thirties have long been stereotyped as cosily conventional. Nothing could be further from the truth. The Golden Age of Murder tells for the first time the extraordinary story of British detective fiction between the two World Wars. A gripping real-life detective story, it investigates how Dorothy L. Sayers, Anthony Berkeley, Agatha Christie and their colleagues in the mysterious Detection Club transformed crime fiction. Their work cast new light on unsolved murders whilst hiding clues to their authors' darkest secrets, and their complex and sometimes bizarre private lives. Crime novelist and current Detection Club President Martin Edwards rewrites the history of crime fiction with unique authority, transforming our understanding of detective stories, and the brilliant but tormented men and women who wrote them.
