Double agents, divided loyalties and institutional secrecy drive Charles Cumming’s modern spy novels. A Spy by Nature introduces Alec Milius, an outsider drawn into British intelligence work and manipulation, while The Trinity Six follows an academic investigating whether the Cambridge spy ring had another hidden member.
