Despite being well-travelled as the BBC’s world affairs editor, John Simpson doesn’t roam far from home in his spy thriller, Moscow, Midnight (John Murray, £20). Life and art intermingle, in both subject matter and character. The hero is named Jon Swift, a veteran journalist bristling under new media regimes. When government minister Patrick Macready is found dead — presumably from a solo sex game gone wrong — Swift takes it upon himself to clear up a few loose ends.
