Philip Kerr, Quercus, £17.99
Field Grey is Philip Kerr's seventh novel about the private detective Bernie Gunther. It begins in 1954. On his way out of Cuba, Gunther is captured by the Americans. After months of incarceration in Guantanamo Bay he is transferred to Germany, where he undergoes interrogation. As US agents question Gunther about his past, the story casts back to his time as a police inspector in 1930s Berlin, and to an episode in occupied Paris, after which he is sent to Russia during the German offensive of 1941.
