Murder's Shield (Destroyer Series #9)

Someone's killing off America's criminals, and it isn't Remo Williams! Well-heeled drug dealers and pimps, crooked judges and mafiosi who had once been untouchable are suddenly being assassinated. It's one thing for there to be a single extra-legal death-dealer like Remo—not quite answerable to the President, but operating within understood parameters—and quite another for a wave of self-righteous vigilanteism to take over. Now that the killings have begun, when will they end? Who decides who lives and who dies?

Remo Williams is The Destroyer, an all-American cop recruited—through highly unorthodox methods—to serve in CURE, a covert government organization. Trained in the esoteric martial art of Sinanju by his aged Korean mentor, Chiun, Remo is America's last line of defense against mad scientists, organized crime, ancient undead gods, and anything else that threatens the Constitution. An action-adventure series leavened with social and political satire, the Destroyer novels have been thrilling readers worldwide for decades.
