A young man was found mutilated and strangled in a flat in Glasgow. Rushing there in the middle of the night, forensic scientist Rona McLeod notices a clear resemblance between the murdered man and herself. Rona is struck by a terrible thought: what if this unfortunate man is her son, whom she gave up for adoption seventeen years ago. Feeling acutely guilty, Rona vows to expose the guy’s killer and find her own son. But influential scoundrels who lure and ruin naive young people by making acquaintances with them on the Internet have no problem destroying it.
