The visitors each said they were greeted by a tall woman who spoke with an Eastern European accent, who led guests up a marble staircase to a study on another floor. At the base of the stairwell, one of the visitors said, Mr. Epstein had placed a chess board with custom figurines, many dressed suggestively — each piece, he noted, was modeled after one of his staffers.

He decorated the home with other oddities, like a life-size female doll hanging from a chandelier, and had arranged a small dining room to resemble a beach scene.

A wall of the study was covered with photographs of famous people, including Woody Allen, and another that Mr. Epstein pointed out was of Crown Prince Mohammed bin Salman of Saudi Arabia.
