New York, 1958. Even though Evelyn Murphy has made progress conquering her agoraphobia by leaving the Pinnacle, she still feels most comfortable in her father's hotel. With Malcolm Cooper, her new boyfriend and fellow employee at the hotel, Evelyn feels prepared for whatever happens next. In this case, it's throwing a big fundraiser with the who's who of New York City.

The night is a success, and Evelyn finally takes up Malcolm's offer to finally visit his apartment in Yonkers. As the party ends, they sneak away to the garage to get Evelyn's car. But Evelyn's always been good at finding things, and she discovers the dead body of a guest, Judge Baker, in a car--with a needle in his arm.

Detective Hodgson and his new partner, Detective McJimsey, arrive on the scene, but before they can begin to question Evelyn, they are startled by another mysterious discovery: there's a woman in the trunk of the car, and she screams as soon as she sees Evelyn's face. Tangled up in the police investigation, Evelyn's got another problem, too--her father insists she break off her relationship with Mac. The next day, her father is found attacked just like the judge, only this time the detectives find a dead woman nearby.

With Mac accused of the attacks and in police custody, Evelyn will have to find the killer on her own before she's checked out of the hotel--this time, for good.
