One main theme could be the concept of eschatology, which might involve ideas about the end of times or a major upheaval. In a spy novel context, it could be related to the potential end of a certain regime or power structure that the spy is involved in. Another theme might be the internal 'tremor of intent' within the characters, like the moral and ethical dilemmas they face while carrying out their espionage tasks.
