Spying doesn’t just involve spies. It’s possible for civilians to become involved and not even know it. Falling in love is a common one. A woman may be romanced because a handler needs access to her home as a safe haven, or because it’s useful for surveillance. From the case officer’s standpoint, a broken heart is a very small matter. That’s because he knows his operation, if successful, could obtain the release of terrorist hostages, or delay the spread of nuclear technologies. An espionage professional cannot carry the burden of emotion. It is unlikely his convenient lover will even receive a goodbye.
