The city can be a strange place, full of odd sights. Sometimes chilling sights. But nothing could prepare the detectives of the 87th Precinct for the sight of a murdered young woman, a member of a local college track team, hanging from a lamppost. Nor could they be ready for the news that the same night, another woman is raped for the third time--by the same man. Two cases, two perpetrators, one chilling evening.
