With perfectly crafted characters, riveting and authentic police procedure, and a satisfying breakneck pace, Sean Lynch's the Fourth Motive is nothing less than a tour de force of the detective thriller genre. - Mark Greaney- #1 New York Times bestselling coauthor of Command Authority With Wounded Prey, Sean Lynch delivers a hell for leather, wild ride of a debut with the been there done that authenticity that lifts it above other thrillers. I just added Farrell and Kearns to my short-list of favourite characters, and Vernon Slocum to my worst nightmares! Think First Blood meets No Country For Old Men. - Matt Hilton, bestselling author of the Joe Hunter series Knowing my predeliction for reading crime books written by those who have experienced this world at first hand, Sean Lynch was an absolute find for me! With not only experience as an Infantryman in the US Army and a long career in law enforcement, Lynch is perfectly placed to imbue this novel, a brutal and bloody tale of the pursuit of a psychopathic killer, with a frighteningly accurate depiction of the essential natures of both killer and pursuer - and yes, this is definitely not one for the more nervous nellies among you, so be warned. Personally, I couldn't fault this visceral, violent and completely enthralling thriller. - Raven Crime Reads Sean Lynch understands his heroes and what drives them, and while they have considerable skills on their side, Slocum is a true monster, his reign of terror is shocking, and he really does seem larger than life. While redemption is the biggest theme of the novel, the author also deftly explores the inner workings of a very, very sick mind, and what made Slocum what he is. Be prepared to go to the dark side in this harrowing, fast-paced thriller. - Kristin Centorcelli at Criminal Element
