Palmer continues to live a relatively happy life, until he smells an odd scent that appears to be only recognisable by himself. Finding its source swiftly becomes an obsession. Tracing it ostensibly to Lisa's room, Palmer reads her private diary and discovers her secrets before succumbing to the scent. Removing all traces of his trespass, Palmer discovers a minute - but familiar - hole in Lisa's wall abutting the basement. Locating an old camera, he begins to take a prurient interest in her, taking compromising candid photographs of her without her knowledge.
