The hero of Robinson`s novels (Wednesday`s Child, etc.), Yorkshire Chief Inspector Alan Banks, appears in three of this collection`s 13 stories, and one of the 13, 'Innocence,' won the Canadian Crime Writers Award for best short story. That tale displays well Robinson`s gift for turning a familiar plot inside-out as strange circumstances overwhelm his characters. A man waits outside a school to meet a teacher friend, draws the suspicion of parents and finds himself charged with the murder of a schoolgirl. What happens after his trial is shocking but, in Robinson`s hands, perfectly believable. There`s a similar twist in the title story, wherein an out-of-town visitor ventures nervously into an urban park often described as unsafe at night. There`s danger, all right, but not what the reader expects. In 'Fan Mail,' a mystery novelist agrees to advise a Walter Mitty-like husband on innovative ways to murder his wife; an old secret leads to a perverse result. The plots of the stories are mostly solid and the characters are always vivid. U.S. readers may particularly enjoy Robinson`s take on his fellow Canadians coping with Florida and southern California.
