Geordie Sharp is asked to undertake an SAS operation so outrageous that his conscience will barely allow him to carry it out. The ostensible aim of Operation Nimrod is to train a new Spetznaz unit to combat the threat of the Russian Mafia, but Sharp's orders contain a sinister hidden agenda. When two SAS men are lifted by Mafia agents, the British authorities' secret weapon is turned against London and only Geordie Sharp can save the day. The Kremlin Device is an unremitting police-racing thriller from start to finish, by Sunday Times top ten bestselling ex-SAS novelist Chris Ryan.
