A new book about Woody Allen’s film career includes allegations that Mia Farrow, his former partner, was abusive toward their children and coached their daughter, Dylan, to accuse Mr. Allen of sexual abuse. An excerpt from the book, which will be published Tuesday, was provided by its publisher, Knopf.

Moses Farrow, the adopted son of Mr. Allen and Ms. Farrow, made the accusations in an interview with Eric Lax, who has had a friendly professional relationship with Mr. Allen for decades and has written extensively about him. Mr. Lax’s new book is “Start to Finish: Woody Allen and the Art of Moviemaking.” Moses has spoken out before about his family and the abuse case, but his remarks to Mr. Lax go into far more detail.

The original investigation into Dylan Farrow’s allegations, which were first made in 1992, took several turns. A doctor who headed the investigation, John M. Leventhal, who interviewed Dylan nine times, said there were inconsistencies in her story. A month later, a Manhattan judge sided with Ms. Farrow, awarding her custody of their children and calling Mr. Allen “self-absorbed, untrustworthy and insensitive.” Frank S. Maco, a state’s attorney in Connecticut, later said there was probable cause to charge Mr. Allen, but he would not do so — to avoid causing further trauma for Dylan.
