The Falcon in Danger

After a passenger plane crash lands at a local airport, bystanders and first responders are shocked to find there is no one aboard. Besides the pilot, captains of industry and wartime contractors, Stanley Harris Palmer and Wally Fairchild are also missing, along with valuable securities. Palmer's daughter and Fairchild's niece hire the Falcon to locate their whereabouts. Morley, a larcenous antiques dealer, and his two murderous sons send ransom notes to the girls, but by the time the Falcon starts negotiations with them, Palmer turns up on his own without Fairchild with an incredible explanation involving a plane hijacking. The Falcon is dubious.
