From the NYT bestselling author of The Mystery of Mrs. Christie—a thrilling story of the five greatest women writers of the Golden Age of Mystery and their bid to solve a real-life murder.

London, 1930. The five greatest women crime writers have banded together to form a secret society with a single goal: to show they are no longer willing to be treated as second class citizens by their male counterparts in the legendary Detection Club. Led by the formidable Dorothy L. Sayers, the group includes Agatha Christie, Ngaio Marsh, Margery Allingham and Baroness Emma Orczy. They call themselves the Queens of Crime. Their plan? Solve an actual murder, that of a young woman found strangled in a park in France.

May Daniels, a young English nurse on an excursion to France, seemed to vanish into thin air as she prepared to board a ferry home. Months later, her body is found in the nearby woods. The murder has all the hallmarks of a locked room mystery for which these authors are famous. Determined to solve the highly publicized murder, the Queens of Crime embark on their own investigation, discovering they’re stronger together. But soon the killer targets Dorothy Sayers herself, threatening to expose a dark secret in her past that she would do anything to keep hidden.
