Heartbreak Hotel (Alex Delaware #32) by Jonathan Kellerman

Alex Delaware and Milo Sturgis investigate the death of Alex’s most mysterious patient to date in the sensational new thriller from the master of suspense, #1 New York Times bestselling author Jonathan Kellerman.

At nearly one hundred years old, Thalia Mars is a far cry from the patients that child psychologist Alex Delaware normally treats.

But the charming, witty woman convinces Alex to meet with her in a suite at the Aventura, a luxury hotel with a checkered history.

What Thalia wants from Alex are answers to unsettling questions—about guilt, patterns of criminal behavior, victim selection. When Alex asks the reason for her morbid fascination, Thalia promises to tell all during their next session. But when he shows up the following morning, he is met with silence: Thalia is dead in her room.
