Paul Caine was a young, red-haired, freckle-faced undercover police detective from Philadelphia. He was assigned to investigate a series of brutal murders, wherein three women had been strangled with black silk stockings. One of his primary suspects was a confidence artist named Henry Francis. In June of 1967, Caine tracked Francis and his wife, Rachel to the town of Collinsport, Maine. Paul remained in Collinsport until he could properly recuperate from his injury, after which, he returned to Philadelphia.
