"Bloody Falls of the Coppermine, Madness and Murder in the Arctic Barren Lands" by McKay Jenkins

Covers some of the Douglas group and Hornby in the back ground of 2 priests that first visit the Copper Eskimo in the early 1900's. I pretty much read it straight through. Couldn't stop. I think author Farley Mowat tells a similar tell about the same story in one of his books.
