Then, out of the Arctic darkness, comes a stranger a terrifying giant of a man claiming that Sigs father owes him a share of a horde of stolen gold and threatening awful violence if Sig doesnt reveal the golds whereabouts. Sig knows nothing about the gold, but he does know that theres a loaded Colt revolver hidden in the cabins storeroom a gun that his father had said would protect him, but which his mother had abhorred.
