Mister X

A page-turner to the nail-biting end, the fifth Frank Quinn investigation (after 2009's Urge to Kill) will leave readers breathless. After leaving the NYPD, Frank Quinn created his own investigation agency, joined by his former partner, Larry Fedderman, and his former lover, Pearl. Five years before, the notorious serial killer called the Carver claimed his last victim, Tiffany Keller. The cops have given up on catching the murderer, so Tiffany's twin, Chrissie, begs Quinn to reopen the case. Then Chrissie disappears, and the Carver starts killing again. Slimy police commissioner Harley Renz warns Quinn to back off of his investigation, but Quinn, Fedderman, and Pearl know they may be the only ones who can stop the killer. Misleading clues and dramatic suspense will keep readers pondering the intricacies of this twisty, creepy whodunit long after the last page is turned. (Oct.)
