Twelve years ago, four-year-old Timmy Cable vanished suddenly from a wild and lonely stretch of East Anglian beach. After a massive police search fails to find a body, the boy is presumed dead. Now, on a quiet street in Cambridge, Timmy's mother, still wracked with grief, is drawn to a teenage street musician—and feels desperately certain that this tall, blond boy must be her son. Has the long nightmare of loss ended at last? If so, where has Timmy been all these years? And why, whenever the boy is questioned about his past, does he become strangely hostile? It falls to private investigator Laura Principal to ferret out the truth. Is this young stranger with a badly bruised face truly Timmy Cable? Or is he merely a dangerous interloper, bent on taking the wealthy Cable family for a lucrative ride? And what can explain the trail of violence that begins with his arrival— and ends with murder?
