London, 1958. Newly promoted Chief Superintendent Frederick Troy of Scotland Yard reluctantly takes a European trip with his brother. But in Vienna, Troy crosses paths with an old acquaintance: British-spy-turned-Soviet-agent Guy Burgess, who makes an extraordinary confession: "I want to come home." In this 8th outing (following A Lily of the Field) Troy knows this news will cause a ruckus in London, but he doesn't expect that an MI5 man will gunned down as a result—and Troy himself suspected of the crime. As he fights to prove his innocence, Troy finds that Burgess is not the only ghost who has returned to haunt him.
