The new high-tension, high-stakes thriller from the first woman to head MI5. MI5 Intelligence Officer Liz Carlyle is summoned to a meeting with her boss Charles Wetherby, head of the Service's Counter-Espionage Branch. A Middle East peace conference is planned to take place at Gleneagles in Scotland and several heads of state will attend. The Syrians have learned that two individuals are mounting an operation to disrupt the peace conference in a way designed to be spectacular, laying the blame at Syria's door. The source claims that Syrian Intelligence will act against the pair, presumably by killing them.
