Ancient Greece - 466 BC. Blackmailed into spying for Spartas hated secret police, High Priestess Iliona's investigations keep turning up the same stories of a one-eyed giant that lives in the hills above Sicily - the legendary Cyclops. But soon Iliona comes to realise that the threat to her country doesn't come from the so-called Cyclops, or even their arch-enemy, Athens - it comes from deep within Sparta itself.
