The January 1936 issue of NEW MYSTERY ADVENTURES, in addition to another fine Saunders cover, also features William Bogart's "The Silent Accuser".  Bogart's chief claim to fame is probably as the author of a number of Doc Savage stories.  In 1946, apparently in need of some quick cash, Bogart cobbled together a couple of his Doc Savage stories to create "The Crazy Indian," which appeared in MAMMOTH ADVENTURE, November 1946.  Doc was renamed as Rush Randall.  However, his editing job was lackadaisical, and the characters sometimes appear under the names Doc, Monk and Ham!
