Dr. Toni Ezralow appears in The Bone that Blew.
A rich dermatologist and pilot, she is an expert liar. She was having an affair with Calvin Warren after he told her company secrets about Richard King's business that made her a lot of money, she flew him to New York for the weekend and spent the full two days "thanking him".
She claims her husband wouldn't care even if he'd known. Her son plays lacrosse with Royce King. When Royce was injured during lacrosse Calvin took him to Toni instead of the ER. According to her she and Calvin once took Alexa and Royce out on flight.
After Calvin was murdered, Toni's skills as a liar were shown as she nearly outwitted Booth during interrogation until he managed to present her with her flight record.
