Having dispatched a trio of strong silent types to Grantham p.i. Benny Cooperman's bedside to get his attention and deliver him to a previously unannounced meeting, Abram Wise, Canada's greatest unconvicted crook, tells Benny that somebody's been making a series of attempts on his life, and that Benny is hereby elected to head the killer off. Who wants to see Wise dead? Only his two ex-wives, waitress Paulette Staples and teacher Lilian Wise; their respective children, underachieving Hart Staples and clotheshorse Julie Wise; and half the Ontario constabulary. But Benny's attention fastens instead on a 40-year-old murder case his friend McKenzie Stewart has just written up in a true-crime book: the conviction of Mary Tatarski, the next-to-last woman to be executed in Canada after a second unseen burglar fortuitously killed her mother five years after a first break-in left her father dead--an especially timely case to be ventilating again since Ed Neustadt, the retired cop who headed the investigation that sent Mary to the gallows, has just given McStu's book a big publicity boost by getting himself murdered. Benny's return (A Victim Must Be Found, 1988, etc.) is an amiable retro puzzler marked by endless rounds of Q-and-A with the unmemorable suspects, much of it clever but none of it believable for a moment.
