Emerson Hough 
Mississippi Bubble [PDF ebook] 

Emerson Hough made his name as a writer of Westerns, but the frontier lawyer also had a keen interest in the rough tapestry of American history as a whole. In this historical novel, he details the remarkable life of Scottish economist John Law, who put his controversial business ideas to work in Mississippi and Louisiana and caused a financial mess so profound that he had to flee the region disguised as a female traveler to preserve his own safety.
