SPY Historian Vince Houghton sat down with University of Southern California history professor Steve Ross to discuss the ongoing research for his upcoming book Hitler in Los Angeles: How Jews and their Spies Foiled Nazi Plots Against Hollywood and America. Ross explains how a group of patriotic citizens refused to wait for the authorities to act on the Nazi menace in America, and instead took matters into their own hands. A never-before-told true story of classic infiltration and espionage in the 1930s and World War II.
