Twenty literary greats. One victim. Can you solve the puzzle - and the murder?

The Literary Detectives Murder Club are gathered in the library at Murderly Manor when disaster strikes: the Literary Critic is found dead in the study, his whisky laced with poison. The Literary Critic has never written a novel, but he has ruined dozens. Every member has the motive and means for murder, and Inspector Jigsaw suspects them all. Can you piece together the puzzle, follow the clues on the fold-out poster, and use your deductive powers to crack the case?

You can enjoy this as a standard jigsaw puzzle - or step into the role of detective with the bonus murder mystery. Don your finest deerstalker hat, pick up your magnifying glass and solve the case using the fold-out poster. Record your deductions, then open the envelope to check your answer.

The twenty suspects are fictionalized versions of some of the most iconic crime writers of all time, from the 'Queens of Crime' Agatha Christie, Dorothy L. Sayers and Ngaio Marsh, to the hardboiled kings Raymond Chandler, Dashiell Hammett and Chester Himes. Also in the line-up are celebrated contemporary novelists, including Richard Osman, Jo Nesbo and Asako Yuzuki - bringing global relevance and wide audience appeal.
