Rock Hudson and his wife Phyllis Gates

Rock Hudson's wife once confronted him for being gay, Judy Garland kept several caches of drugs hidden throughout her house, and Marilyn Monroe and John F. Kennedy were recorded having sex — all this according to newly uncovered files from former cop-turned-private investigator Fred Otash. The files, which had been hidden in a storage unit, were given to The Hollywood Reporter by Otash's daughter Colleen.

Otash, who was one of the inspirations for Jack Nicholson's character in Chinatown, was a notorious freelance investigator in the 1950s and '60s. L.A. Confidential novelist James Ellroy met Otash several times before his death and even wrote Shakedown, an e-book featuring a fictionalized (and not so flattering) version of Otash. Now that Ellroy is developing an FX pilot based on Otash's life, Colleen hopes that releasing some of his secret files will counter Ellroy interpretation of her father.

Among the highlights in the files, which fill 11 overflowing boxes, are a transcript of when Rock Hudson's wife grilled the actor about his exploits with men and how a Rorschach test he had taken seemed to indicate that he was a homosexual.

Otash's notes also detail how he was hired by Marilyn Monroe to install listening devices in her home. The private eye reportedly listened to Monroe have sex with President John F. Kennedy and another time heard a confrontation between Monroe, Bobby Kennedy and JFK's brother-in-law Peter Lawford on the day Monroe died.

Otash also details moving in with Judy Garland, who contracted him to protect her after her split from third husband Sid Luft. He allegedly found several hidden stashes of pills in Garland's home, all of which he flushed down the toilet.
