Il vello d’oro

The legendary Golden Fleece exists and is found in the Misty Mountains! Thus declares Professor Stanislaw Shimkoziewic, basing himself on documents that attest that the story of the Argonauts is partly true. Digging Bill, forever in search of lost treasures, as well as Zagor and Chico, accompany the Professor on his trip to the Misty Mountains. But an incredible tribe of flying women appears to hinder their way: the Harpies!
