While searching for a phone charger, she opens a bedside drawer and finds a child’s drawing of a house with a face in the window, and on the back is an unfinished note from the previous nanny, Katya.

The note begins with “To the new nanny” and warns the recipient to “please be—” before stopping abruptly, leaving Rowan with a sudden prickle of unease.

Rowan maintains her composure to impress Sandra, offering to help clean the floor, but while cleaning her shirt in the utility room, she is accidentally seen by Jack Grant, causing them both intense embarrassment.

Rowan feels a wave of panicked nausea and manages to escape to her room, realizing that Bill is likely the reason many nannies have left so quickly.

Later that night, she is woken by the sound of heavy, slow footsteps pacing in the ceiling above her room, which is physically impossible because she is on the top floor and there is no attic hatch.
