A Lonely Newcomer

A Young Person Out of Place
Loss of Familiar Friends
Ethan misses Boston and has no established social circle in New York. He is homeschooled and depends on swimming and his parents’ arrangements for contact beyond the family.

A Biological Mother Appears
A Secret Meeting
Katie visits Ethan while his adoptive parents are away. She brings photographs and tries to tell him about his early life and her efforts to reconnect.

A Story Used as Cover

Manipulating Anna
Performed Vulnerability
Ethan cries, describes his father as frightening, and accepts Anna’s sympathy. He uses her training as a psychologist to encourage the interpretation he wants her to believe.
Control Through Disclosure
He gives Anna selected facts and conceals his own violence. His closeness to her is part of a strategy to keep attention away from Katie’s actual killer.
The Confession and Threat

The Mask Falls
Admission of Murder
Ethan tells Anna that he killed Katie with a letter opener and that he had been entering her house at night. He explains how he used her personal information to access her phone and accounts.
A Threat Against Anna
His charm gives way to direct menace. He threatens to kill Anna and treats her life as another situation he can manipulate.
The Fall Through the Roof

A Fatal Pursuit
Anna Fights Back
On the roof, Ethan corners Anna and tries to force her off the building. She reaches the trellis and takes up gardening shears, resisting rather than surrendering.
The Skylight Gives Way
Anna embraces Ethan and pushes him onto the fragile skylight. It breaks beneath him, and he falls into the house; Anna later reports his death to the police.
