Spy Novels About Betrayal, Compromise and the Job

For readers who enjoy espionage through the people doing the work and those made to live with its consequences. These novels follow recruitment, source handling, office rivalries, divided loyalties and the strain of carrying a cover into private life. British and American institutions sit alongside Korean, Chinese and Spanish perspectives, with the historical setting and reading order explained where useful. Some choices are brisk operations; others ask for patience with a voice, a marriage or a long institutional memory.
