Isolation becomes absolute. Harper, her former assistant, accuses her of workplace harassment. The hospital suspends her. Henry Callahan shows up again, this time with a different attitude. Softer. More attentive.

—“I know you’re not like him, Nora. But you need help. Someone’s manipulating you.”

—“Why do you believe me?” she asks, exhausted.

—“Because I have secrets too.”

Nora doesn’t know if she can trust him. But loneliness weakens her. She lets him stay for one night. They talk. Even laugh. He tells her he lost his sister to a killer. That he understands what it’s like to carry a past that doesn’t belong to you.

But when she wakes up, Henry is gone. And her computer is on. Files opened. Photos. Medical reports. Someone has accessed her private information.

Terror settles in again. What if Henry is part of this? What if he always was?

Paranoia consumes her. She locks herself in. Changes the locks again. Installs cameras. But the messages keep coming. Unsigned notes. Photos of her house. And a new threat: “If you don’t finish the cycle... I will.”
