Another serial psycho-killer from a specialist in the genre. Roger Dyce is a Connecticut insurance agent who likes to inject young men of Scandinavian extraction with a paralyzing drug, drain their blood (slowly, over several days), and dress them in the clothing of his beloved grandfather before dismembering their bodies. As he's disposing of his eighth victim, Dyce is drifting uncharacteristically toward Helen--a supermarket checker whose life expectancy dramatically declines--and eyeing as his next victim Eric Brandauer, a young tough who has ideas of his own. When his trap to catch Eric lands him in the hospital with an Eric-broken nose, Dyce comes face to face with his nemesis/double John Becker--an ex-FBI agent who quit the Bureau out of fear of his uncanny empathy for killers and his own growing propensity for violence. The plotting of thrust and counterthrust, and the morituri musings, are chillingly understated. Creepy stuff, all right.
