A vigilante serial killer, named "the Will of the People", is prowling New York, ruthlessly executing evil-doers whom he feels deserve to die. His m. o. is to alert the media before he strikes. So far, his victims have included a child molester, a Mafia don, a violent anti-abortionist, and a racial hate monger. But when "Will" targets a noted lawyer, Matthew Scudder is called upon to stop a frighteningly efficient killer who can do the seemingly impossible. Ads in "People" and "The New Yorker". HC: William Morrow. (Fiction--Mystery)
