When Ernest Fletcher is found bludgeoned to death in his study, everyone is shocked and mystified: Ernest was well-liked and respected, so who would have a motive for killing him? Superintendent Hannasyde and Sergeant Hemingway, with consummate skill, uncover one dirty little secret after another, and with them, a host of people who all have reasons for wanting Fletcher dead. Who tiptoed into the study to do the deed? The rather nefarious nephew Neville? A neighbour's wandering wife? A fat man in a bowler hat? Then a second murder is committed, with striking similarities to the first, giving a grotesque twist to a very unusual case.
