THE LONE TRAIL WHAT THIS STORY IS ABOUT When a novel by an unknown writer runs into its thirty-seventh thousand it must be something unusual. Blue Pete: Half-Breed was something unusual. In Luke Allan's new story an old friend reappears, Inspector Barker of the Mounted Police. Blue Pete is not here; but in his place there is the delightful little tenderfoot journalist Morton Stamford, who blunders into a drama full of thrills and incident. The description of the H-Lazy Z Ranch with Dakota Fraley and his outfit is a real Luke Allan piece of vigorous writing. For the weak of heart to read The Lone Trail is sheer murder-or should it be suicide?
