In 1981 she got the idea of making a documentary with Foucher about her grandfather. But after several trips to Cuba to interview the writer's friends and acquaintances, she realized the project was in a chaotic state. "I became very depressed," she said years later. "No one was interested in what I had to say, and everything seemed like it was out of control." In 1985 she called off the project, divorced Foucher—and dived head-first into despair. "I drank more and more and was slowly killing myself with alcohol," she recalled. "My thoughts were erratic, and I had trouble with my memory. I thought about suicide periodically, especially when I was drinking heavily."
The previous year, Hemingway had injured herself skiing in Austria; during her nine-month recovery she gained 75 pounds and sank deeper into depression. A 28-day stay at the Betty Ford Center in 1987 probably saved her life. Emerging trim and looking healthy, she devoted herself to running, yoga, painting, singing and to cooking dinners in the Manhattan apartment she shared with Stuart Sundlun, a businessman she had met on a blind date before entering rehab in 1987. But she was also anxious to resume her acting career, and when her role in the 1990 French movie Love in C Minor failed to gain Hollywood's attention, she did what many a struggling actress has done: posed nude for Playboy.
Her centerfold helped pay off the $900,000 in back taxes she owed the IRS but led nowhere. After she and Sundlun broke up in the early '90s, Hemingway turned her attention to what she called healing her spirit. She consulted with a Cheyenne Indian medicine man. She learned about the shamanic art of the Northwest Coast Indians. She had training in the huna philosophy of the Hawaiian kahunas. And in 1993 she began working with a network of chiropractors to treat her lifelong battle with dyslexia, her epilepsy and her bulimia, a problem from her modeling days. "I needed to go inside and clear the blockages," she told PEOPLE in 1994, "because nothing was coming to me, no jobs, no work."
In some ways, Hemingway did seem at peace. "She was a real phenomenal person," says Sundlun, who remained a friend. "She had a light touch on a heavy life." Model Cheryl Tiegs, a friend since the high times of the '70s, warmly remembers, "She was totally into the great outdoors. That was her main interest. She would come out to my house in Montauk [N.Y.] and sit on the beach, communing with the sea gulls. Everyone would come in the house and whisper and think it was kooky." Her unusual ways got a similarly affectionate reaction just two months ago at the Doral Saturnia spa in Miami, where she was the celebrity guest at a PEOPLE magazine function. "We'd all be yapping, and all of a sudden you'd address a question to Margaux, and she'd have her head down and her hands together, praying over her food," says PEOPLE editorial projects manager Louise Lague. "There was something spiritual going on."
In 1994, in pursuit of even greater spirituality, Hemingway took a trip to India, where she spent two months visiting holy sites. But according to Dr. Elin, the trip went badly. "Some sort of a breakdown happened over there," says Elin. "We don't know if she had a [epileptic] seizure followed by a breakdown or what. But whatever happened, the people there were unaccustomed to her condition, and she supposedly spent some time in jail. We eventually got her back, and she was hospitalized."
According to the Toronto Star, it was her father who consulted a psychiatrist and was instrumental in getting her treatment at a private clinic in Twin Falls, Idaho. But the crisis did not break the family impasse. "She's blaming Mariel or me or Jack [for her hospitalization]," Angela told PEOPLE soon after Hemingway was released early in 1995. "It's everybody else's fault. She's 40 years old and she's got to take responsibility for her life."
Sadly, now, she will never get that chance. Whatever the cause of death, Hemingway seemed confused in her final hours. At around 4:30 on Friday, June 28, she called Elin and left a message on her answering machine. "She didn't sound okay," says Elin. "She was slurring. She was just rambling. Her last sentence to me was, 'God loves you, God loves you, and I love you too.' " She had tried valiantly to climb back from the depths of depression, but clearly the former million-dollar model—whose most recent gigs included making infomercials for home-improvement products, promoting the Psychic hotline and filming straight-to-video films for a relatively measly $35,000 or so a pop—still had a way to travel. Last week the door to the Santa Monica apartment Hemingway hoped would be home to happier times swung open after the police had left. On the balcony a potted fern was blowing in the breeze. Unpacked boxes still stood on the floor. "It's very difficult when people don't want you anymore," says Elin. "She was just a gentle loving soul who got lost in fame and fortune."
