"Tricky," she says, considering the problem nonetheless. "We'd have to invent a class for the Servant and hope that we haven't mistakenly guessed a spy's class. I've seen Rider and Lancer; that leaves Assassin, Archer, Berserker, Caster. To choose a hero who might as easily be one as another--as easily Assassin as Archer, as easily Berserker as Caster--might lend credibility to the ploy."

A considering pause. "Perseus. Armed with the head of the Gorgon and his own reflective shield, which makes an Assassin of him, since he kills by trickery. And he played at quoits and threw the discus--a bit of a stretch, but I suppose that would make him Archer well enough. And Caster, because the gods gave him gifts willy-nilly."
