The blocky image of a hulking man on the computer monitor at Sunset Investigations was totally unexpected. His sense of humor is definitely demented; his hints to the Detectives not to be taken lightly. He has killed, and intends to kill again, and again, and again. MARCUS is up for the challenge, as is his partner. Hot on the bumper of their suspect, he and FRANK are privileged to share the experience of plummeting over a cliff in Marcus' new car. Surviving was a breeze, according to their behavior afterwards. Except for victims, clues are not piling up. The serial killer knows his business, but then so do the Detectives. They are confident of turning it around. MRS. P. isn't a slouch, either. Her computer skills are focused to help in the capture of the SLASHER. A second chase winds up in desert ranchland, where cattle are witness to the ultimate confrontation.
