Murder in the Basement - Grand Format

When two newlyweds discover that a corpse has been buried in the basement of their new home, a gruelling 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 on 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 colourful cast of teachers hides the victim - and perhaps their murderer.
