Meet Freddy Otash: corrupt cop turned sleaze hustler, extortionist, pimp, and an actual historical figure who made the 1950s magazine “Confidential” the go-to source for the sins of the rich and famous. In his prime, Freddy raised hell, and in the pages of “Shakedown” he finds himself in purgatory — literally — waiting for a transfer. Will he make it to heaven, or is his fate trending south? Promised redemption if he confesses, Freddy writes a tell-all peopled by Hollywood greats like Liz Taylor, Marilyn Monroe, John Wayne, and Gary Cooper (to name a few), who are up to all sorts of wrong. Threesomes, foursomes, men’s room misadventures — anything goes in this licentious world
