The Black Rose

It was 1984, October 21, ten days before Halloween. Salem, Massachusetts, would never be the same. One young girl from Salem High School took it upon herself to solve as terrifying a crime as she would ever face. What she discovered was beyond her worst nightmare.
The horror began on the night of October 20. The first body was found next to an old abandoned church. The body was of a young woman. She had been beheaded, probably from being accused of witchcraft, and next to the decomposing body lay a black rose. But what did it mean?
Two more young girls vanished the next night. Their bodies were also found next to old abandoned churches. They were also beheaded, and a black rose was left beside each body. There was a serial killer at work.
