When known mercenary Robert Morgan is spotted at a top-secret disused Soviet arms dump (of which, apparently, there are several in this country), he obviously has to be brought in for questioning. Especially as the powers that be soon realise that a missile has gone missing. It seems that someone — a terrorist group, presumably — is planning a devastating strike on a London target. And Morgan knows who it is and when it's going to happen, so it's up to MI5 to get him to talk.
While their investigation methods are startlingly clever, their interrogation methods are far more back-to-basics (sleep deprivation and that sort of thing). Adam Carter doesn't actually beat the suspect up, but he's just half a step away from torture. It's a story that throws up some difficult ethical dilemmas about how far agencies should go to protect the public. Is it all right to blackmail innocent people to get the information you want? Is it acceptable to threaten the lives of a suspect's family?moreless
