La bufera

The rebellious Indians attack the Overland fort, but the white renegades who were supposed to open the doors to them have been neutralized and the Indians find in Tex and the army too many bones to chew! As for Tom Blackburn, the scoundrel who had planned everything, he was killed in Denver, where he conspired under a respectable identity. Meanwhile, in Alaska, the Indians who traded furs with Gros-Jean disappear into thin air. Tex and Kit Carson, called for help by their friend, face the fury of the Indians of the Great North, used to shooting mysterious black arrows.
