An empty death - Laura Wilson

War-torn London hides a killer without a face...Summer, 1944. War-weary DI Ted Stratton is called to investigate when a doctor is found dead in suspicious circumstances near Fitzrovia's Middlesex Hospital, and he soon realises that someone involved is not who they appear to be. Someone has discarded their own identity and can move and kill freely. Meanwhile Jenny, Ted's wife, is working at the local Rest Centre, although her spirit of make-do is wearing thin. When she meets a bombed-out woman declaring that the man who claims to be her husband is an impostor, Jenny thinks it must be shock, but the reality is much stranger and far more dangerous...
