By Sam and Chuck Giancana, "the godson and the brother of Mob boss Sam Giancana." You JFK types will remember that name, and you "I love a good crackpot yarn" types should find something to enjoy in Double Cross, in which the man himself says the Mafia and the CIA are basically the same thing.
This later-edition, larger PB (with a “new foreword by Tim Newark, author of The Mafia At War”) has some visible shelfwear and a handful of dog-eared pages, but is sturdy and clean; it’s a decent reading or research copy.
