THE INFORMANT Perry™s novels”the best ones”are a master class in thriller writing.  The Informant should be the newest addition to that syllabus, read for  devouring first, and analysis thereafter.”Los Angeles Times The  Butcher™s Boy is back. Thomas Perry™s vengeful assassin has returned to  play a deadly psychological game with Elizabeth Waring, the only  Justice Department official who ever believed he existed. The  Butcher™s Boy knows Waring can help him hunt down the Mafia boss who  sent a team of hit men to kill him”and in return he offers her key  information that will help her crack an unsolved murder. So begins a new  assault on organized crime and an uneasy alliance between opposite  sides of the law. As the Butcher™s Boy works his way ever closer to his  deadly enemy in an effort to kill him first, Waring is in a desperate  struggle, either to force her unlikely ally to become a protected  informant, or to take him out of commission for good. Excellent .  . . Perry offers a compelling, rapid-fire plot, credible Mafia and FBI  secondary characters, an indictment of self-serving officialdom, and the  old soul-shattering moral dilemma: what is truth?”Publishers Weekly
