The Woman Who Couldn't Die

We have a brilliant scientist in Dr. Pareso, a foreigner who has come mysteriously to this country. He interests a young reporter, David Law, in some of his experiments, and when, with the assistance of a young Viking, Knutsson, and Law, the three start on their astounding quest for the woman who has been frozen in the northern ice tomb for centuries-then the story really starts.
The descriptions of the hardships the three men endured on their way north thru the wilds before discovery of the Lost Tribe, are very good. The plot is absolutely unique and the result is an entirely different mystery story.
