The Henchmen of Zenda

Jasper Detchard is a disgraced British officer, now selling his blade to the highest bidder. Currently that's Michael Elphberg, half-brother to the King of Ruritania. Michael wants the throne for himself, and Jasper is one of the scoundrels he hires to help him take it. But when Michael makes his move, things don’t go entirely to plan—and the penalty for treason is death.
Rupert of Hentzau is Michael's newest addition to his sinister band of henchmen. Charming, lethal, and intolerably handsome, Rupert is out for his own ends—which seem to include getting Jasper into bed. But Jasper needs to work out what Rupert’s really up to amid a maelstrom of plots, swordfights, scheming, impersonation, desire, betrayal, and murder.
Nobody can be trusted. Everyone has a secret. And love is the worst mistake you can make.
