One of the Claridge's kitchen porters is found dead - strangled. He was a recent employee who claimed to be Romanian, but evidence suggests he may have been German. Detective Chief Inspector Coburg has to find out exactly who he was, and what he was doing at Claridge's under a false identity. Once he has established those facts, he might get an insight into why he was killed, and who by. Coburg's job is complicated by the fact that so many of the hotel's residents are exiled European royalty. King George of Greece is registered as 'Mr Brown' and even the Duke of Windsor is staying, though without Wallis Simpson. Clandestine affairs, furtive goings-on and conspiracies against the government: Coburg must tread very lightly indeed .
