Following the success of The Floating Admiral, in which certain members of the Detection Club-including Agatha Christie, Dorothy L. Sayers, and G. K. Chesterton-collaborated on a whodunit, six writers pooled their talents to create another coauthored mystery. This time the premise had an added twist: authors would swap their detective characters, allowing for some extremely entertaining parodies of one another's sleuths.
When a ruthless British newspaper tycoon is shot dead in his home, the high-level suspects include the assistant commissioner of Scotland Yard, casting doubt on the impartiality of a formal police investigation. As a solution, the home secretary brings in four brilliant detectives to solve the murder: Mrs. Bradley, Sir John Saumarez, Lord Peter Wimsey, and Roger Sheringham.
