Camping out near their suburban homes, Matt and his best friend Parker happen on a body floating in a creek and promptly (and correctly) link it to George Evans—Parker's mother's employer and close friend—whom they happen to spot immediately afterward. The outcome here is never in much doubt, but Hahn—whose other perceptive, suspenseful novels include Following the Mystery Man (1988) and The Doll in the Garden (1989)—raises this above formula by the believable responses of her characters to their perilous situation, and by the sobering realism of having Parker's mother involved in the drug trafficking that led to the crime. Meanwhile, readers will be caught by the adventure: after telling the police, the boys do some sleuthing on their own, have a number of hairbreadth escapes from Evans and his unsavory partner in crime, and complete a neat series of clever entrapments and escapes by luring one culprit into a "heffalump trap" that they had constructed earlier. Good, well-constructed entertainment.
