By now, you likely know the story of Woody Allen's alleged assualt of his then-7-year-old daughter Dylan in 1993. Dylan has written and spoken publicly about the alleged assault several times over the past few years, claiming that Allen took her into the attic of her mother Mia Farrow's country home in Connecticut and, while she lay on her stomach watching an electric train set roll by, assaulted her.

The allegations were investigated by authorities in both New York and Connecticut, who declined to prosecute after determining that the evidence was insufficient. Dylan, according to the New York Times, was interviewed nines times, and an investigator found that her recollection of the alleged assault was inconsistent and that "she changed important points from one interview to another." Allen, over the years, has always denied the allegations.

While Allen never faced criminal charges, the allegations have stuck. Former Allen collaborators like Colin Firth, Greta Gerwig, Mira Sorvino, Timothee Chalamet, Natalie Portman, Reese Witherspoon, Kathleen Kennedy, America Ferrera, Tracee Ellis Ross, Shonda Rhimes, and others have said that they won't work with the director again. Allen's son Ronan Farrow, the journalist who broke the story of Harvey Weinstein's alleged assaults, has repeatedly disavowed his father as well.

But there's another brother, Moses Farrow, who was 14 years old at the time of the alleged assault, and he has a very different story to tell.

Today, Moses, who is now a therapist, published his own account of what happened on the day of the alleged assault and what life was like under Mia Farrow's roof. It's a truly harrowing tale, from Moses's perspective: Mia, he claims, was violent, mercurial, manipulative, and punished her children severely for the slightest offense. "I was defeated, deflated, beaten and beaten down," he writes. "Mia had stripped me of my voice and my sense of self. It was clear that if I stepped even slightly outside her carefully crafted reality, she would not tolerate it. It was an upbringing that made me, paradoxically, both fiercely loyal and obedient to her, as well as deeply afraid."

Of the day in question, he writes:

As the “man of the house” that day, I had promised to keep an eye out for any trouble, and I was doing just that. I remember where Woody sat in the TV room, and I can picture where Dylan and Satchel were. Not that everybody stayed glued to the same spot, but I deliberately made sure to note everyone’s coming and going. I do remember that Woody would leave the room on occasion, but never with Dylan. He would wander into another room to make a phone call, read the paper, use the bathroom, or step outside to get some air and walk around the large pond on the property.

Along with five kids, there were three adults in the house, all of whom had been told for months what a monster Woody was. None of us would have allowed Dylan to step away with Woody, even if he tried. Casey’s nanny, Alison, would later claim that she walked into the TV room and saw Woody kneeling on the floor with his head in Dylan’s lap on the couch. Really? With all of us in there? And if she had witnessed that, why wouldn’t she have said something immediately to our nanny Kristi? (I also remember some discussion of this act perhaps taking place on the staircase that led to Mia’s room. Again, this would have been in full view of anyone who entered the living room, assuming Woody managed to walk off with Dylan in the first place.) The narrative had to be changed since the only place for anyone to commit an act of depravity in private would have been in a small crawl space off my mother’s upstairs bedroom. By default, the attic became the scene of the alleged assault.

In her widely-circulated 2014 open letter in The New York Times, the adult Dylan suddenly seemed to remember every moment of the alleged assault, writing, “He told me to lay on my stomach and play with my brother’s electric train set. Then he sexually assaulted me. He talked to me while he did it, whispering that I was a good girl, that this was our secret, promising that we’d go to Paris and I’d be a star in his movies. I remember staring at that toy train, focusing on it as it traveled in its circle around the attic. To this day, I find it difficult to look at toy trains.”

It’s a precise and compelling narrative, but there’s a major problem: there was no electric train set in that attic. There was, in fact, no way for kids to play up there, even if we had wanted to. It was an unfinished crawl space, under a steeply-angled gabled roof, with exposed nails and floorboards, billows of fiberglass insulation, filled with mousetraps and droppings and stinking of mothballs, and crammed with trunks full of hand-me-down clothes and my mother’s old wardrobes.

The idea that the space could possibly have accommodated a functioning electric train set, circling around the attic, is ridiculous. One of my brothers did have an elaborate model train set, but it was set up in the boys’ room, a converted garage on the first floor. (Maybe that was the train set my sister thinks she remembers?) Now, whenever I hear Dylan making a public statement about what allegedly happened to her that day when she was barely seven, I can only think of that imaginary train set, which she never brought up during the original investigation or custody hearing. Did somebody suggest to the adult Dylan that such a specific detail would make her story more credible? Or does she really believe she remembers this train “circling around the attic” the same way she says she remembers Woody’s whispered promises of trips to Paris and movie stardom (kind of odd enticements to offer a 7-year-old, rather than a new toy or a doll)? And all this apparently took place while those of us who promised to have our eyes trained on Woody were downstairs, seemingly oblivious to what was happening right above our heads?

Eventually, my mother returned with Casey and her newest adoptees, Tam and baby Isaiah. There were no complaints by the nannies, and nothing odd about Dylan’s behavior. In fact, Woody and Mia went out to dinner that night. After dinner, they returned to Frog Hollow and Woody stayed over in a downstairs bedroom – with, apparently, no abnormal behavior by Dylan, and no negative reports from any of the grown-ups.

The next morning, Woody was still at the house. Before he left, I briefly wandered into the living room and witnessed Dylan and Satchel sitting with him on the floor by a wall with a big picture window. The kids had a catalogue from a toy store and were marking off the toys they wanted him to bring back on his next visit. It was a cheerful, playful atmosphere – which would soon seem jarring compared to what Mia would allege happened less than a day before. Many years later, I once mentioned my recollection to Woody, and he said that he, too, remembered it quite vividly, telling me how he had told Satchel and Dylan to mark one or two toys each, but they had laughingly managed to check off virtually every toy in the catalogue. He remembers bringing it back to the city with him, with the intention of purchasing a few of the items they had checked. He told me he wound up holding onto that catalogue for years, having no idea that he would never see his daughter again.

There's a lot more in this piece (you can read the whole thing here), but after years of estrangement from his father, Moses reconnected with Allen several years ago and is now estranged from his mother—whom, he says, forbade him—as an adult—from contacting his dad. "I am grateful to have awakened to the truth of what happened to us," he writes, "but disappointed that it took me this long to get here."

Moses doesn't think his sibling is lying about her experience. But he does think Dylan and Ronan were manipulated by their very angry mother into believing things that just never took place. And Mia had a good reason to be pissed: Seven months before the alleged assault, she discovered that Allen was engaged in an intimate relationship with Soon-Yi Previn, Mia's adopted daughter with André Previn. Presumably, it was her own relationship with Allen, not the age difference between the two, that enraged Mia Farrow. As Moses writes, "My mother, of course, had her own darkness. She married 50-year-old Frank Sinatra when she was only 21. After they divorced, she moved in to live with her close friend Dory Previn and her husband André. When my mother became pregnant by André, the Previns’ marriage broke up, leading to Dory’s institutionalization. It was never spoken of in our home, of course, and not even known to me until a few years ago." (And, contrary to every rumor about their relationship, Woody Allen was not Soon-Yi's father or her father figure, as Moses details in his piece.)

Of course, it is possible that Mia Farrow and Woody Allen are both guilty. But, as Moses points out, after six decades in the public eye, not a single other accuser has come forth. "As a trained professional," he writes, "I know that child molestation is a compulsive sickness and deviation that demands repetition. Dylan was alone with Woody in his apartment countless times over the years without a hint of impropriety, yet some would have you believe that at the age of 56, he suddenly decided to become a child molester in a house full of hostile people ordered to watch him like a hawk." Moses, however, was there, and he doesn't believe it ever took place.
