I due stregoni

The Viking King Guthrum, an old acquaintance of the Spirit with the Hatchet, asks for Zagor's help. The news of horrible crimes, arriving from the coast west of Boston, raises suspicions that the psychopathic seer Starkad, defeated by Zagor and the Vikings some time before, is actually still alive. Zagor, Chico, Guthrum and his warriors leave for the coast aboard Baron La Plume's flying ship, on a journey that soon turns out to be full of dangers... Having arrived in Stonington, a small village on the coast of Maine, Zagor, Chico, King Guthrum and his warriors have confirmation that Starkad is still alive. Zagor and his friends, following his trail, reach the solitary island of White Rock, where the renegade seer went in search of mysterious finds. On the solitary cliffs, an old abandoned lighthouse lights up on foggy nights and ghostly figures emerge from the sea, while the menacing figure of a second sorcerer who works alongside Starkad becomes more and more concrete... On the trail of Starkad and the revived Kandrax, Zagor and his adventure companions arrive in New York, where the island of Manhattan is pervaded by a wave of homicidal madness that has forced the army to intervene. Our friends, fighting against time to save King Guthrum, cross the city devastated by madmen to reach the archaeological museum, where the two sorcerers intend to officiate a bloody ritual in the shadow of the dolmens!
