On the planet Cicero Prime, the kingdom of Cardenas is divided, with the whole population forced to swear allegiance to either the effete Duke or the fiery, hard-edged Duchess. This is a situation both parties have grown tired of. What use is half a kingdom when, thanks to a carefully engineered murder, you could have it all?
Surely, neither of them would be rash enough to summon the deadly off-world assassin The Scorpion to help with their problem? And surely, this terrifying figure wouldn’t arrive wearing a long cream coat and striped trousers…?
