December, 1940. With the Luftwaffe pounding the city nightly, Londoners seek refuge in underground stations.

Aldwych has been taken out of service to provide shelter for the British Museum's priceless Elgin Marbles, as wellas civilians escaping the bombing.

When the body of a young man is discovered on the tracks, wearing eveningdress but barefoot, Detective Chief Inspector Coburg and Sergeant Lampson are on the case. Before long, more bodies are discovered, and Coburg's wife Rosa becomes a target for the brutal killer.

Caught up in a world of underground jazz clubs, abandoned tube stations and looters, Coburg and Lampson must track down the ruthless murderer before it's too late.
