After almost five years of conflict, London's exhausted inhabitants are living in a world of dereliction. War-weary DI Ted Stratton is no exception, but he cannot help being drawn in by his latest case. Called on to investigate when a doctor is found dead in Fitzrovia's Middlesex Hospital, Stratton soon realizes that someone involved is not who they appear to be. Meanwhile Jenny, Ted's wife, is working at the local Rest Centre. When a bombed-out woman appears at the centre, declaring that the man claiming to be her husband is an imposter, Jenny thinks that it must be due to shock. The reality, however, is far more dangerous... Ultimately, for Stratton and Jenny perhaps there is only one thing they can trust: their fear.
