From the author of Legacy, now a major BBC Film, comes a brilliant new novel for fans of le Carre, Graham Greene and Charles Cumming.

Charles Thoroughgood is now the recently-appointed chief of a reconstituted MI6, tasked with halting the increasingly disruptive cyber attacks on Britain, which are threatening government itself and all the normal transactions of daily life - not to mention a missing nuclear missile-carrying submarine. The murder of one of Thoroughgood's former agents and the escape from prison of a former colleague turned traitor, whom Charles helped convict, brings danger on all sides.Thoroughgood ploughs a lonely furrow in Whitehall in his belief that all these elements are connected, a theory which dramatically gains credibility when his wife, Sarah, disappears.
