Even if you don’t know Fred Otash (though many fans of James Ellroy or old Hollywood will), you know his work. As a former LAPD officer turned private eye for (and against) the stars, he was involved in much of the gossip that came out of Hollywood in the 50s. He was one of Confidential magazine’s main informants, and he worked a number of movie star divorces. Otash was also, by his own account, quite a playboy, bagging starlets left and right. And that’s the sort of self-aggrandizement you can expect in Investigation Hollywood! Though his career was an exciting one, and he has the dirt on literally everyone, this book is only intermittently compelling. Sometimes it feels like a hardboiled riff on Hollywood Babylon, sometimes it feels like braggadocios stories he’d tell at a party. Some of the anecdotes are compelling, some rehash familiar tales, and some are too vague to leave an impression. I wish he’d invested the work with more psychological insight, as he did in one of the more compelling pieces, about Charles Schnee. Investigation Hollywood! is more interesting as an artifact than art, and even the gossip isn’t as juicy as you’d hope; we’ve heard these stories before, because Otash is the one who helped break them.
