Foreign Policy has a nifty primer on how spies of used sex and romance to learn secrets. The nice history lesson stretches from WWII to the present.
The trade name for this type of spying is the “honey trap.” And it turns out that both men and women are equally adept at setting one — and equally vulnerable to tumbling in. Spies use sex, intelligence, and the thrill of a secret life as bait. Cleverness, training, character, and patriotism are often no defense against a well-set honey trap. And as in normal life, no planning can take into account that a romance begun in deceit might actually turn into a genuine, passionate affair. In fact, when an East German honey trap was exposed in 1997, one of the women involved refused to believe she had been deceived, even when presented with the evidence. “No, that’s not true,” she insisted. “He really loved me.”
Those who aim to perfect the art of the honey trap in the future, as well as those who seek to insulate themselves, would do well to learn from honey trap history. Of course, there are far too many stories — too many dramas, too many rumpled bedsheets, rattled spouses, purloined letters, and ruined lives — to do that history justice here. Yet one could begin with five famous stories and the lessons they offer for honey-trappers, and honey-trappees, everywhere.
