America's favorite team of super sleuths is back for another season. Wesley Cowan, independent appraiser and auctioneer; Gwendolyn Wright, professor of architecture, Columbia University; Elyse Luray, an independent appraiser and expert in art history; and Tukufu Zuberi, professor of sociology and the director of the Center for Africana Studies at the University of Pennsylvania are once again investigating the homes, possessions and family histories of curious contributors from around the country. Using the latest investigative technology, the team of experts continues to uncover surprising facts about our nation's history.

In their sixth season premiere, the history detectives investigate the diary of a WWII pilot; an 1856 book purported to be the memoirs of a New York woman married to a Mormon elder; and an 1853 Napoleon coin said to be shot by Annie Oakley.

A flag that may have been carried into battle by one of the few African-American infantry regiments in WWI; a painting that may be the work of Seth Eastman; and a two-story building that may have housed a Chinese Tong.

A balloon scrap that may be a missing piece of a secret weapon; a circus program that connects a society woman, FDR and the Boy Scouts; and a letter from Ronald Reagan that links a Navy captain to the development of Camp David.
