The next morning, Baines takes Philippe on a trip to the London Zoo, where Julie meets with them, and accompanies them back home for dinner in Mrs. Baines's absence. The three return home, where Philippe finds a telegram from Mrs. Baines, notifying her husband she will return in two days. The three have dinner, and afterward play a game of hide-and-seek. Later that night, Mrs. Baines returns to the house unexpectedly, finding her husband in bed with Julie. She awakens Philippe before attacking Baines, and slapping Phillipe in the process. The two get into an argument on a staircase landing, which Philippe partially witnesses. When Baines locks himself in the guest bedroom with Julie, Mrs. Baines walks onto an unguarded ledge on the landing, where a window faces directly into the bedroom. In the process, she slips and falls to her death, landing at the foot of the staircase. Philippe does not witness the accident, and presumes that Baines pushed her to her death.
