Albert Johnson is famous in Canadian crime history for leading Mounties on a sensational and deadly chase through the Yukon and Northwest Territories during the winter of 1931-32. How he managed to elude police over hundreds of kilometers in subzero temperatures through a mountainous wilderness is as much a mystery as his real identity. To this day, very little is known about the man nicknamed "The Mad Trapper". My guest, Helena Katz, Canadian historian and author, joins me to talk about her book, "The Mad Trapper: The Incredible Tale of a Famous Canadian Manhunt".
