"I pick up my axe and fight like a bomber now, but you still blast me down to the ground." Before becoming Jimi Hendrix's manager, Michael Jeffery had been a covert op for British Intelligence. According to one of his original clients, Eric Burdon of the Animals, Jeffery often boasted of his 007 escapades during the Cold War -- staging assassinations in Greece, torturing KGB agents, blowing up Russian/Egyptian bases in the Suez. The Animals' singer, Jimi's future close friend, took these stories as drunken tall tales until, early one morning, the former MI6 agent invited him out to the London harbor where the U.S. Seventh Fleet happened to be trolling for some lost nukes. His manager emerged from the water in scuba gear, holding a black box. Pointing out to the armada, the ex-spy pulled a switch: suddenly the harbor was rocked with underwater explosions. "Like most people of felonious intent," Burdon wrote in his memoir, "he was charming, attractive, and sometimes a riot to be around." Jeffery had made the transition from demolition and espionage to rock and roll by studying under "The Al Capone of Pop" himself, Don Arden. Also known as "The English Godfather," Arden, Sharon Osbourne's father, went on to manage the Small Faces, Electric Light Orchestra, and Black Sabbath. He was known for his old-fashioned business methods -- bribery, blackmail, assault, kidnapping. Jeffery proved his own mettle against his mentor when he stole the Animals away from him without losing life or limb. The retired spy parlayed his MI6 and Arden experience to become a rock and roll Dr. No. "His own mob sprang up around him like morning mushrooms," Burdon wrote. "... His main enforcer was The Turk, a nasty bastard whose tools of choice were an ax and two highly trained German shepherds." The singer went on to describe how Jeffery burnt down his Club Marimba for the insurance money, then how he absconded with the Animals' money. In the fall of 1966, the Animals' bassist, Chas Chandler, discovered Jimi Hendrix in New York, flew him to London, and introduced him to Jeffery. The two co-managed the guitarist and helped him assemble the Experience. Several years later, Chas and Jimi became estranged due to creative differences. "The window of opportunity was there for Jeffery to scoop it all up," he said. "I knew that something dodgy was gonna happen. But I never dreamt it would lead to his [Jimi's] death." In his own memoir, bassist Noel Redding described Jeffery's fondness for guns, throwing knives, electronic bugging devices, and roadie spies. As for his financial skills, to discourage frivolous audits, the ex-spy kept all his business records in Russian. Jeffery toured Jimi and the Experience relentlessly after their apotheosis at Monterey Pop in '67. By '69, the guitarist was earning $100,000 per gig, but was too exhausted and drugged out to realize that he was virtually broke while Jeffery was a multi-millionaire with off-shore numbered bank accounts. At last, burnt out on touring, Jimi told his manager he was disbanding the Experience. No sooner did he reveal his intention than he was busted for heroin possession in Toronto. He came to suspect that Jeffery, desperate that he might lose his cash cow, had engineered the bust so he, Jimi, would be forced to keep the Experience alive to foot his legal expenses. Four months later, just after Woodstock, Hendrix was kidnapped at gunpoint, held hostage for several days, then "rescued" in a dramatic shoot-out at his Woodstock compound. Soon he came to suspect that his manager was behind this intimidation, too. Still refusing to surrender to Jeffery and revive his golden goose, the Experience, Jimi formed the Band of Gypsys. At their premiere Madison Square Garden gig in January of 1970, Jimi collapsed on stage after only a few songs. Buddy Miles insisted he'd seen Jeffery slip him two tabs of bad acid. "He didn’t want Jimi playing in an all-black band," the Gypsys' drummer declared. "One of the biggest reasons why Jimi is dead is because of that guy." Later that summer, Hendrix escaped New York for London, telling his friend and future biographer, Sharon Lawrence, "Lately I've been thinking that I'm circled by wolves." By this time, terrified of Jeffery, the star was in secret negotiations with Miles Davis's manager, Alan Douglas. Hearing through one of his informants in Jimi's entourage of the possible defection, Jeffery accused Douglas of "trying to steal my artist." After his Isle of Wight performance, Jimi lay low in London trying to avoid Jeffery, who had followed him there. Meanwhile, he finalized a new management deal with Douglas. On the morning of September 17, Douglas phoned Hendrix's New York lawyers, informing them that he would be relieving Jeffery of his management duties. This meant that not only would Jeffery lose his cash cow, but that his nemesis Douglas would, in taking over the books, discover his embezzlement and mismanagement over the years. Meaning the end of Jeffery's career, if not imprisonment. The next morning an ambulance, called by an unidentified party, screamed to the Samarkand Hotel where Hendrix was staying with his girlfriend, Monika Danneman. The paramedics found the door open, the flat abandoned, and a body on the bed covered in vomit. Dr. John Bannister, the physician on duty at St Mary Abbot's hospital when the ambulance arrived, later testified, "Jimi Hendrix had been dead for some time.... Red wine was coming out of his nose and out of his mouth. It was horrific." He described how he tried to clear the singer's windpipe with an 18-inch metal sucker, but finally gave up due to the inexhaustible volume of liquid. "Someone apparently poured red wine down Jimi's throat to intentionally cause asphyxiation after first causing barbiturate intoxication," Dr. Bannister concluded. "Without the ability to cough he was easily drowned." Waterboarding and Forced Ingestion were commonly used by MI6 and other intelligence agents during the Cold War. It was a preferred interrogation or assassination technique since it left no marks on the body. Almost no alcohol was found in Hendrix’s blood. Moreover, friends stated that he didn't drink red wine. The coroner, Dr. Gavin Thurslon, listed the cause of death as "inhalation of vomit following barbiturate intoxication." As for the cause of this fatal condition itself, the pathologist left an "open verdict." The paramedics, doctors, and hospital staff did not learn that the victim was Jimi Hendrix until later on. To them the body seemed to be just that of another anonymous black man who had ODed. Within hours of Jimi's death, all his hotel rooms and crash pads in London as well as New York were turned over: clothes, instruments, writings, drugs -- everything vanished. An investigation was not launched until twenty-three years later when all evidence was long gone. Noel Redding, who died all but penniless in 2003, wrote that murder was "a distinct possibility." In his 2009 title, Rock Roadie, James Wright wrote that Jeffrey, his employer, confessed to the murder in 1971. "That son of a bitch was going to leave me," the manager said. "If I lost him, I’d lose everything." Instead, he gained a fortune: his management contract was renewed by default, he reaped the immense profits of posthumous record sales, and he collected on a $2 million dollar insurance policy which he had taken out on the star. Michael Jeffery reportedly perished in a mysterious plane crash over France in 1973. But his remains were never found. Eric Burdon, Noel Redding, and others believe he may have checked luggage but slipped away during the boarding process. Jeffery was due in London court the very next day to defend himself in several huge lawsuits relating to his embezzlement, money laundering, and fraud. - David Comfort David Comfort is the author of three popular Simon & Schuster titles, and the recipient of numerous literary awards.
