Late Bee Gees legend Robin Gibb had a shocking past that was buried deep in FBI files until his death earlier this year, and RadarOnline.com has learned that drug-induced delusions sparked the singer's alleged blackmail and murder plot.
The Saturday Night Fever musician first came under FBI scrutiny in the early 1980s for allegedly threatening and trying to blackmail the lawyers representing his then-wife, Molly Hullis, the New York Post reported, when the files were released to them through a Freedom of Information Act request after Gibbs lost his battle with colon cancer at age 62 in May.
London law firm Haymon & Walters first reported Gibb to federal agents after it “received numerous threatening telegrams" allegedly from the Bee Gee, including a telegram ranting: "What you have done is just about the limit. I warned and warned you.
"The situation is now very serious. Know sic one walks all over me... I have had enough," he allegedly wrote, claiming he had taken out a contract on his wife's life. "It is now a question of time."
The diet of potent uppers and downers led Gibb to believe that his estranged wife, whom he married in 1968 after a whirlwind romance, was involved in a plot to try to steal his millions, leading him to break into her house with a private detective when she was away in New York.
Thirty years later, Molly and Robin's divorce and custody battle remain one of the dirtiest in rock 'n roll history packed with jealousy, deceit, money and dark secrets.
Their volatile relationship began in a burst of violence when within weeks of falling for each other in 1967, the couple was on a train that crashed in south-east London, killing 49 people. Robin pulled Molly out of their derailed carriage through a smashed window and they were married a few weeks later.
Gibb and his brothers were soon catapulted to the top of the pop charts and while the band toured around the world, both his marriage and his mental health suffered due to his rampant drug-taking and womanizing.
"Robin was an odd person anyway, but when he was on pills, which he was for most of the time I knew him during his first marriage, he could say or do anything," his former manager Chris Hutchins told the Mail Online.
"He was always seeking a treatment for his drug addiction. He’d work through the night, never going to bed. Night and day meant nothing to him. He took uppers to keep him awake and downers to put him to sleep.
"His house at the time was a beautiful Georgian place near Harrods. One time, I noticed handprints on the walls, about 8 feet up. Obviously, some very strange sexual adventures had been going on," Hutchins recalled.
The marriage imploded in May 1980, when Molly tracked him down to a New York hotel room and told him it was over. Despite his infidelities with hundreds of women, Robin believed that she had actually been cheating on him and became obsessed that one of her attorneys was planning a cunning sting operation that would make him go public with his suspicions and then sue him for libel.
To prove his fantasy, Gibb stole a cache of papers from Hullis' house and handed them over to the British police and FBI, then hastily arranged a press call on a Concorde flight to Miami.
Molly passionately denied the claims and police — powerless to act over the burglary because it was still technically the marital home — found the so-called "bombshell evidence" contained no proof of his allegations that he was being set up.
On March 23, 1981, the FBI decided to close out its investigation into Gibb because Hullis and her lawyers did not want to press charges.
He eventually lost the custody battle for children Spencer, 6, and Melissa, 4, and would not see them for a further six years.
After his divorce from Molly was finalized, he married second wife Dwina Murphy, a druid priestess who had a sexual drive as rampant as his own and encouraged him to give up drink and drugs.
