An invitation to a treasure hunt open to thriller writers and lesser mortals confronts Scotland Yard's Chief Inspector Macdonald with two baffling deaths.-- Kirkus Reviews

It's all fun and games (and fake names) until someone ends up dead...

Amidst the confusion of too many fake names, clues, ciphers, and convoluted alibis, Chief Inspector Macdonald and his allies in the CID must unravel a truly tangled case in this metafictional masterpiece, which returns to print for the first time since its publication in 1937. This edition includes an introduction by CWA Diamond Dagger Award-winning author Martin Edwards.

Should detectives go to parties? Was it consistent with the dignity of the Yard? The inspector tossed for it--and went.

Chief Inspector Macdonald has been invited to a treasure hunt party at the house of Graham Coombe, the celebrated publisher of Murder by Mesmerism. Despite a handful of misgivings, the inspector joins a guest list of novelists and thriller writers disguised on the night under literary pseudonyms. The fun comes to an abrupt end, however, when Samuel Pepys is found dead in the telephone room in bizarre circumstances.
