In Henry Porter's new novel A Spy's Life, Bob Harland, a former MI6 agent, is now with the UN, investigating fresh water resources in Asia and eastern Europe. On his way back to New York in a UN jet, one minute he's chatting to an old friend, Alan Griswald, ex-CIA, now working for the War Crimes Tribunal, the next he's up to his neck in the mud of the East River, still strapped into his seat. The investigation puts the crash down to wake-vortex caused by a Boeing 767, but Harland is not convinced. Too many odd things are happening to him.
