A female character gets "honeytrapped"?

She’s not being blackmailed, though. She’s blissfuly unaware of her lover’s duplicity right up to the moment he snaps her neck.

Althugh it could be said Bond took some rides on top of her, her name was Vesper, not Vespa.

I was going to say the same.

Yeah, neither of mine were really blackmail examples…

Fun fact: The woman was played by Stana Katic, aka ‘Kate Beckett’ on Castle.

In the HBO series Rome a gang leader named Memio has one of his subordinates seduce the daughter of his rival Vorenus. Memio then surprises his man and the daughter (named Vorena) in bed together and threatens to tell her father. Vorena, knowing her father would kill her lover, agrees to become Memio’s mole in her father’s organization.

In Tom Clancy’s 2000 novel The Bear and the Dragon,

a Japanese-American male CIA agent seduces the female secretary of a top Chinese Communist leader so that he can gain ongoing remote access to the leader’s computer system. It’s not for blackmail, though.

That’s the first one that occurs to me also

In one of Wilbur Smith’s books, the black terrorist seduces Shasa Courtney’s wife as part of his 'Guy Fawkes" plot.

The past half-season of the ABC TV series Scandal featured a plot where an agent sought to seduce the main character to provide leverage for his shady boss.

Just to nitpick, Cortez doesn’t set up the assassination. In fact, he’s righteously pissed when he gets back to Columbia because the assassination compromised his source (because the FBI checks out who had Director Jacob’s schedule, which leads to the secretary which leads to Cortez). I hated how they changed this in the movie, turning Cortez from devious villain to plain asshole.

Frederick Forsyth also uses the honeytrap in The Cobra, in which a drug lord’s daughter falls for a handsome young man and tries to run away with him only to find out that a kilo of Columbian puro has somehow slipped into her baggage. Her incarceration is used to get the cartel figure to give up a list of corrupt officials around the world.
