"Write the report, move on," Detective Al Stimpson said as he closed the file on Magenta Epperson, prostitute, who had been strangled and mutilated. Less than a month later, another victim--prostitute, strangled, mutilated--sends Stimpson and his partner on a race to find the killer. Evidence that this unknown person has killed over a long period of time and location leads the formation of a task force. The combined work force works to capture a killer that keeps the ring finger of the right hand as his souvenir.
