An over-the-hill FBI man pursues a telepathic vigilante who stalks and executes serial killers: a penny dreadful from a pair of authors whose literary pedigrees include two previous novels (Lady El, 1992, etc., not reviewed) and stints in the comic-book field. While recovering from a near-fatal accident at a construction site, attorney David Vandemark discovers he can read other people's minds. He also learns that his wife and child have been slain by a homicidal maniac known to the police as Mr. Clean. Keeping his unexpected gift to himself, the bereaved young widower vows to rid the world of vermin who prey on the innocent. Seven years and 20 cutthroats later, the self-anointed exterminator is still on the loose, though federal agent Ira Levitt has been on his trail from the start. When news breaks that a new murderer is slaughtering Latino families in New York City, both men head for Manhattan. Once in the Big Apple, David (a past master at assuming false identities) manages to enlist the wholehearted aid of comely Angela Quinones, the sole survivor of a close-knit Cuban clan butchered by the unknown psychopath. Delving into the case of the massacred Hispanics, David (whose extrasensory powers don't work with Angela) realizes he's on to a horrific conspiracy sanctioned by Washington. In an unlikely turn of events, then, the one-man wrecking crew (now in love with Angela) shares his suspicions with Ira, who reluctantly agrees to help him thwart the dastardly scheme. David apparently perishes in the course of an assault that torches a secret lab, produces a double-digit body count, and brings to a close the government's hellish project. Angela drops from sight as well. But after recuperating from wounds suffered in the climactic battle, canny old Ira tracks her down and gets the true story of his longtime quarry's fate. Implausible plotting and undistinguished prose: pulp fiction of a low order.
