SPY Historian Vince Houghton sat down with Vin Arthey, who has spent most of his adult life researching the life of KGB Colonel William Fisher – better known as Rudolf Abel. Working with secret sources and inside information, Arthey turned this lifelong study into a fascinating book, Abel: The True Story of the Spy They Swapped for Gary Powers. Houghton and Arthey trace the adventures (and misadventures) of one of the most extraordinary characters in the history of the Cold War.
