A novel pairing dark humor and intelligent detection work, this 1932 "whowasdunin?" mystery is an example of a celebrated Golden Age author's most inventive work. This edition includes an introduction by CWA Diamond Dagger Award–winning author Martin Edwards.

When two newlyweds discover that a corpse has been buried in the basement of their new home, a grueling case begins to trace the identity of the victim. With all avenues of investigation approaching exhaustion, a tenuous piece of evidence offers a chance for Chief Inspector Moresby and leads him to the amateur sleuth Roger Sheringham, who has recently been providing cover work in a school south of London.

Desperate for evidence of any kind in the basement case, Moresby begins to sift through the manuscript of a satirical novel Sheringham has been writing about his colleagues at the school, convinced that amongst the colorful cast of teachers hides the victim—and perhaps their murderer.
