Glasgow's police, P Division, are hard at work, grappling with two major new cases alongside the usual run of mean-streets crime. The body of Sandra Shapiro, at 20 an alcoholic prostitute, has been found buried at the edge of a farm, near the stolen car in which her body was probably transported. And ten-year-old Tim Moore is missing from his middle-class home. Initial investigation has produced no clue to his fate, but something found near the stolen car triggers the memory of a 25-year-old incident in the mind of veteran Sergeant Ray Sussock (Condition Purple, 1989, etc.). It raises the macabre specter of a quarter century of unsolved, perhaps unknown killings and heightens the urgency of finding Tim Moore before it's too late. How this is accomplished, using every tool of modern crime detection, makes for high-tension suspense--in a gritty story enhanced by sensitive insights into the lives of its heroes and victims. Another can't-put-it-down winner for Turnbull.
