A new novel in the Inspector Troy series, a tale of Cold War spy dealings centred around Guy Burgess. It is 1958. Chief Superintendent Frederick Troy of Scotland Yard, newly promoted after good service during Nikita Khrushchev's visit to Britain, is not looking forward to a Continental trip with his older brother, Rod. Rod was too vain to celebrate being fifty so instead takes his entire family on 'the Grand Tour' for his fifty-first birthday: Paris, Sienna, Florence, Vienna, Amsterdam. Restaurants, galleries and concert halls. But Frederick Troy never gets to Amsterdam. After a concert in Vienna he is approached by an old friend whom he has not seen for years - Guy Burgess, a spy for the Soviets, who says something extraordinary: 'I want to come home.' Troy dumps the problem on MI5 who send an agent to de-brief Burgess - but the man is gunned down only yards from the embassy, and after that, the whole plan unravels with alarming speed and Troy finds himself a suspect.

As he fights to prove his innocence, Troy finds that Burgess is not the only ghost who returns to haunt him.
