BETRAYAL OF AN HEIRESS

MARIE-Christophe de Menil’s East 81st Street home was, for years, a haven. The oil heiress and art patron used to host lively, inebriated parties that earned her the nickname Prosecco. After the overdose death of her adored grandson Dash Snow in 2009, de Menil opened her doors to the hell-raising artist’s friends. But more recently, the baroque townhouse has become a crime scene.

On March 2, Alina Morini, a Romanian immigrant who told The Post she spent 15 years working for de Menil and six years living with her — as an assistant, caregiver and friend — was arrested at the home for trespassing. She was, per a summonswith-notice, imprisoned for 30 hours, partly at the notorious Manhattan Detention Complex, a k a The Tombs.

“Christophe did not want me to be arrested,” Morini told The Post. “She put out her hands and said, ‘Arrest me with her.’ ”

Now Morini has filed a lawsuit claiming her arrest was “planned” by Taya Thurman, the daughter of de Menil and her exhusband, Robert Thurman. (He is also the father of Uma Thurman, making Taya and the actress half-sisters.) Morini seeks at least $5 million in restitution from Taya and others for charges including false arrest and imprisonment and wrongful eviction. The filing also claims a “forced and ongoing isolation of [de Menil] at the hands of her daughter,” who was previously estranged from her mother for “more than 30 years.”

Taya has not yet responded to the filing. But a growing group of de Menil’s friends has expressed concerns that they can’t contact the 88-year-old.

“I get calls from people close to her. They say they are cut off and concerned,” attorney Robert Hantman, who represents Morini, told The Post.

“I’m concerned about her well-being. Christophe is one of my oldest and closest friends. I tried for a little over a year now to be in touch and I have not heard back from her. It is very disturbing,” playwright and director Robert Wilson told The Post. “I was told that she was no longer receiving telephone calls and not allowed to see anyone.”

Nico Iliev, a friend of de Menil’s for the past 15 years, wrote a letter to Manhattan Assistant District Attorney Catherine McCaw. Included in the filing are claims that Christophe is being isolated. Iliev wrote: “I was [recently] allowed to visit [Christophe] for 17 minutes . . . During the quick visit . . . she shared that she is ‘in jail.’ ”

He added that Christophe’s “landline and cellphone were disabled.”

Taya’s attorney, Sheila Tendy, told The Post: “Christophe is not isolated from anyone.”

Both sides accused the other of greed. De Menil and her five siblings, heirs to the Schlumberger oil fortune and art patrons who have been called the “Medici of modern art,” are said to be worth more than $100 million.

The summons alleges that Taya was aiming “to exercise greater control over Christophe for . . . selfish economic gain.” Hantman told The Post: “[Taya] wanted to keep away anyone who is close to Christophe and could . . . influence her.”

Meanwhile, Tendy said, “Alina is asking for $5 million for herself. Her claims are to smear the family for financial gain, period.”

NOBODY expected de Menil — a vibrant light on the social scene who has funded works by Philip Glass and Twyla Tharp — to lead such a controversial life in her golden years.

Her parents, John and Dominique de Menil, moved from Paris to the US in 1941, after France fell to the Nazis. Blossoming art collectors, they landed in Houston, where the family’s oil-services firm, Schlumberger Limited, was based.

“Houston was the biggest city in Texas but, at the time, it had very little [in the way of culture],” William Middleton, author of “Double Vision,” a biography of the couple, told The Post.

So John and Dominique started buying art and working with local institutions before launching a privately funded museum of their own, the Menil Collection, in 1987.

Christophe, their eldest daughter, grew up around fine art, living in a home designed by Philip Johnson and decorated by couturier Charles James. In her early 20s, she had moved into her parents’ Manhattan apartment. At age 27, in 1960, she wed Robert Thurman, then 19. Taya was born that year, and the couple divorced in 1961.

She began hanging out with a group of avant-garde artists including musician John Cage, dancer Merce Cunningham and painter Robert Rauschenberg. She put together “happenings” in the Hamptons, supported the work of her favorite performers and designed costumes for playwright Wilson before launching her own fashion line.

Thanks in part to her, the Menil Collection, loaded with some 20,000 works, ranks among the world’s finest small museums. It includes coveted pieces by Pablo Picasso, Max Ernst’s portrait of Dominique, and a Renzo Piano-designed gallery devoted to Cy Twombly.

Wilson recalled how de Menil helped him. “I wrote a play called ‘A Letter for Queen Victoria,’ [about] an autistic boy. I performed it for two months to sold-out houses in Paris. We came to New York and [critic] John Simon said, ‘Robert Wilson takes advantage of a brain-damaged boy and puts him on stage.’ Damn right I did. [The rhythm] was mathematical and the words were constructed like Mozart. But the play was a disaster in New York. Christophe saw it. I woke up one morning and in the mail was a $25,000 check and a note that read, ‘Thank you for this wonderful work. I do not want mention of my name.’ She did not want her name celebrated. She was extremely discreet,” he said.

But pressure was building in her private life. As Wilson described it: “For a number of years there [had] been tension between Christophe and her daughter.”

It seemed that de Menil and her only child disagreed over how to handle Taya’s

wild-child son, Dash. (Taya and musician ex-husband Christopher Snow also share son Max, an acclaimed photographer, and daughter Caroline, an actress.) “Dash was put into a diabolical boarding school,” Morini told The Post. “He complained to Christophe and she got him out.”

Tendy responded, “Alina’s characterization of anything involving Dash is not credible. She is in no position to know.” In Dash, de Menil saw a kindred spirit. “She realized that there was suddenly, in the family, a great artist. She understood him in a way that very few people did. He had problems with drugs but that did not stop her from supporting him as an artist,” Wilson said. “They bonded and he did not have that kind of relationship with his mother.”

Middleton added: “I know that she believed in Dash Snow as an artist. We discussed Dash and his importance.”

Dash ran with a crew of wild creatives, including Dan Colen and Ryan McGinley, who embodied downtown debauchery in the early 2000s. His photography reveled in the controversial — inspired his wild life of sex and drugs and incorporating his own semen, sometimes splashed across photos of cops. It earned him solo shows and a spot in the 2006 Whitney Biennial.

In 1999, Dash, then 18, and his 19-yearold bride, Agathe Aparru, had moved in with de Menil. “Christophe was his life,” said Morini. “They were very close.”

It was through Dash that Morini — who described herself as Agathe’s “godmother” — met de Menil.

“Dash was excited for me to go meet his grandmother,” Morini recalled. “He said she would love me.”

Indeed, the two women became close friends, according to several sources.

Dash fatally overdosed in 2009, leaving behind his wife and their daughter, Secret. Morini was there for de Menil.

“This woman is my best friend, my power, my strength. We became attached at the joint,” Morini told The Post. “The only thing we didn’t have was sex. About six years ago, Christophe broke her hand and asked me to move in with her.”

Some suggest that Morini was like family for de Menil. “Last time I saw Christophe was a Thanksgiving dinner in 2018. It was lovely,” Middleton recalled. “Clearly, Christophe and Alina were close. Members of the family were there, but it felt like Alina was co-host of the dinner.”

According to Wilson, “No way, as far as I could see, was Alina taking advantage of Christophe. She is a friend.”

TAYA doesn’t seem to buy this. Her lawyer, Tendy, said of Morini: “We have tapes of her being [verbally] abusive to Christophe.”

Tendy told The Post that there is audio of Alina being “very condescending . . . ‘You stupid’ this and ‘stupid’ that . . . Nobody would want a person like [Alina] caring for their aging mother.”

Morini acknowledges in the summons that the tape exists. She told The Post that it was recorded by a “maid who was fired” and captures “a stupid argument about going to the Hamptons. Christophe called me names. I called her names . . . People fight once in a while.”

She claims in the filing that Taya “had her wrongfully and illegally expelled from Christophe’s residence,” in which she had been residing for six years.

“Taya started harassing me and she bullied me to go to a hotel,” which the de Menils paid for, Morini said. “They said they would get me a lawyer.”

That lawyer was Cesar de Castro, who is listed on the Tendy Law Web site as “counsel to the firm.” Morini claims in the summons that she was the victim of a “scheme.” Tendy refuted that.

After more than a month in the hotel, Morini told The Post, her attorney advised her to return to de Menil’s townhouse. “Christophe was very excited. She said, ‘Oh, my Lu Lu is back’ — that’s her nickname for me. [Then] the police came.

“I want to be reunited with Christophe. She has a few good years left and I want her to live them with dignity,” Morini said.

In Tendy’s estimation, “Alina Morini is not a friend or a family member. She is a disgruntled person who was arrested for conning her way into Christophe de Menil’s home.”

As for Christophe, The Post was given a statement attributed to her: “I recognize Alina Morini’s words for what they are and I’m very sorry and disappointed. I love my daughter and she has taken good care of me. I don’t support this lawsuit and I wish it would stop.”

But perhaps it is Dash’s widow, who delivered the most damning portrait of this art-world family and their friends. “Not trying to get involved in their messes any longer,” Agathe Snow texted The Post. “I cannot surround myself with such bad energy . . . It is the same story over and over again, no imagination, no soul and no care.”
