October 1940. The Blitz bombing raids continue mercilessly, but when the body of a kitchen porter from Claridge's hotel is found, it is clear that he has not been the victim of a blast: he was strangled. Detective Chief Inspector Coburg has to find out exactly who he was, and what he was doing at Claridge's under a false identity. Armed with those facts, he might get an insight into why he was killed, and by whom. <p/>But the investigation is complicated by the fact that so many of the hotel's residents are exiled European royalty. Clandestine affairs, furtive goings-on and conspiracies against the government: Coburg must tread very lightly indeed .
