Cambridge, 1910

Amateur detectives Jonty Stewart and Orlando Coppersmith seem to have nothing more taxing on their plate than locating a missing wooden cat and solving the dilemma of seating thirteen for dinner. But one of the guests brings a conundrum: a young woman has been found dead, and her boyfriend is convinced she was murdered. The trouble is, nobody else agrees.

Investigation reveals that several young people in the local area have died in strange circumstances, and rumours abound of poisonings at the hands of Lord Toothill, a local mysterious recluse. Toothill's angry, gun-toting gamekeeper isn't doing anything to quell suspicions, either.

But even with a gun to his head, Jonty can tell there's more going on in this surprisingly treacherous village than meets the eye. And even Orlando's vaunted logic is stymied by the baffling inconsistencies they uncover. Together, the Cambridge Fellows must pick their way through gossip and misdirection to discover the truth.
