The mystery man wore black, and he was a real cut-up king. Why else was he leaving blood-red severed hands all over the city? Was he an everyday maniac with a meat cleaver, or did he have a special grudge against the 87th Precinct? Steve Carella and Cotton Hawes went along with the grudge theory, because the black-cloaked killer didn't leave any clues to go on - the grisly hands even had the fingertips sliced off. And how do you nail a murderer when you can't identity or unearth most of his victims? That's what the boys of the 87th Precinct have to do: find a killer before he carves up any more corpseless hands!
