Credence, the sequel to Misdirection, is the second novel in a series of international crime thrillers by Martin Link. Suddenly, 'SITE LOCKDOWN' flashes on every single screen in GCHQ. "Alpha team leader. Can you see what they're up to?" "No." There's a brief pause. What comes next is totally unexpected. I can't hear anything but I feel a sudden, ferocious earache, an incapacitating headache and nausea, and I crumple to the floor. In this James-Bond-meets-real-world thriller, MI5 man Lucas Norton once again finds himself caught up in a high-stakes assault when a sniper in a powerboat takes a pot-shot at his family. Could it be linked to the daring raid carried out at GCHQ, where thieves evade the world's tightest security to steal top secret ultra-high-tech equipment from under his nose? Lucas's first case (Misdirection) culminated in him, and the FBI, losing $48m from an international heist. Now he and his crack team over at GCHQ have only a few days to figure out what the stolen tech can do and where the thieves have gone. It's a search that takes them from London's secret underground railway to a disused WW2 bunker, the FBI's Black Hawk launch bay, the US Embassy and the very heart of MI5. Can Lucas's team stop a brilliantly executed plot to hold the populations of London and New York to ransom? Credence will have you trying to outsmart the world's most advanced intelligence services - and the criminals who are one step ahead of them.
