Signal: A Sam Dryden Novel    by Patrick Lee Order:  USA  Can Minotaur, 2015 (2015) Hardcover, CD, e-Book      Reviewed by Hilary Williamson Patrick Lee brings back his ex-Special Forces hero, Sam Dryden (last seen in Runner) in Signal, another extraordinarily fast paced speculative thriller, filled with violence and shocking twists and turns of plot. The story opens on FBI agent Marnie Calvert at the scene of a terrible crime. Then Sam's death defying adventure begins with a call from his friend Claire Dunham, an electronics expert who now works in private security. She was once a comrade in arms, and is 'one of the few people on Earth Dryden fully trusted.' She summons Sam to join her in Arrowhead and drives him out to a mobile home where they stop a pedophile from carrying out the horrific act that Marnie witnessed. How could that be and how did Claire find out about it? Readers share the thoughts of Mangouste, who works for the villains of the piece and is one of many ruthless killers tracking Claire. Meanwhile she shows Sam a dangerous new invention, a device that 'picks up radio signals ten hours and twenty-four minutes before they're transmitted.' This is what allowed her and Sam to stop a terrible action, but they are now in great trouble themselves. After Claire is captured, Sam will do whatever it takes to get her back, and eventually teams up with Marnie. But how will they stay under the radar of a powerful organization that can predict, and even manipulate the future? You'll just have to read Signal to find out. The premise is fascinating and the plot speedy, violent and totally engrossing. Not to be missed!
