Water leak timeline cracks case in designer's bathtub death at NYC hotel

On the morning of December 9, 2010, staff at Soho House, an exclusive Manhattan hotel, discovered a body submerged in an overflowing bathtub in Room 20. The woman was Sylvie Cachay, a 24-year-old fashion designer whose swimwear line, Syla, had launched to considerable acclaim just four years earlier. She lay in the tub fully clothed in a turtleneck and underwear, the water running at full force. What would eventually convict her killer was not a confession or a witness, but the precise timing of a water leak that seeped through the floor below.

Sylvie had arrived in New York with the kind of ambition that defines the city's creative class. She built a swimwear business from scratch, and by 2010 she was working toward the kind of success that justified the risk. That summer, she met Nicholas Brooks at a social event. He was 24, the same age as Sylvie, but their lives could not have been more different. Brooks had dropped out of college and struggled to hold down work. What he did have was money—a trust fund established by his father, Joseph Brooks, an Oscar-winning composer known for penning the 1977 hit "You Light Up My Life." The elder Brooks would later be arrested on more than a hundred counts of sexual misconduct, but that was a separate tragedy.

Sylvie and Nick bonded over a shared trauma early in their relationship: her dog was struck by a car during their first date. The incident seemed to deepen their connection, but over the following six months, the relationship fractured repeatedly. They broke up and reconciled in cycles. By December, the incompatibility had become impossible to ignore. Sylvie had begun to suspect that Nick was stealing from her. She noticed unusual withdrawals from her bank account and sent him an email accusing him of theft, threatening to involve the police. The confrontation happened on December 8, 2010.

That same evening, despite the tension, the couple met at Sylvie's apartment in the West Village. According to Nick's account to authorities, a fire broke out while he was showering. Sylvie's bed caught fire as she slept. He said he woke her and extinguished the flames. Shaken, they decided to leave the apartment and find a hotel for the night. At 12:31 a.m., security cameras captured them at the reception desk of Soho House, where Sylvie held a membership. Nick told staff that Sylvie needed assistance checking in because she had taken medication earlier. An employee named Kristen Stephens escorted her to Room 20 while Nick completed the paperwork downstairs. Stephens later recalled that Sylvie was eager to sleep.

At 12:45 a.m., a busboy delivered ice to the room. Nick met him in the hallway and they entered together. The busboy testified that during his brief time inside, he saw no one else in the room. Security footage would later show Nick moving in and out of Room 20 repeatedly over the next hour and a half. At 2:11 a.m., while Nick was still inside, guests in the room directly below reported water leaking through their ceiling. Seven minutes later, at 2:18 a.m., Nick left Room 20 for the last time. He went to the lobby, where he encountered another Soho House member named David Raleigh, and the two went out for drinks.

When a second water complaint came in, hotel staff traced the source to Room 20. They knocked on the door at 2:51 a.m. and, receiving no answer, let themselves in. They found Sylvie submerged in the bathtub, the water still running. She was pronounced dead at 3:33 a.m. When Nick returned to Soho House at 5:30 a.m., he found the room cordoned off as a crime scene. He was taken in for questioning and eventually arrested.

The water leak became the prosecution's timeline. It established that Sylvie was alive at 2:11 a.m., when the leak was first reported—meaning she had entered the bathtub sometime between 2:11 and 2:18 a.m., the seven-minute window during which Nick was last seen in the room. The evidence, combined with the financial motive and the deteriorating relationship, painted a picture of premeditation or at least fatal intent. On July 11, 2013, after a lengthy trial, a jury found Nicholas Brooks guilty of second-degree murder. He received the maximum sentence: 25 years to life. The water damage that had seemed like an accident—or perhaps a cover-up—had instead become the mechanism by which time itself testified against him.
