Task: Question Answering
Input (English): Passage: Ann Sutton, the wife of Dr. William Sutton, a successful psychoanalyst, is arrested for shoplifting. Ann is saved from scandal by smooth-talking hypnotist David Korvo. Korvo persuades the store officials to put the mermaid pin she stole on her credit account, and not prosecute. He pressures her into coming to lunch with him, and she is relieved when, instead of accepting the blackmail payment she thinks he is after, he tears up her check and the store record of her shoplifting, and promises to help her.
Ann is anguished about her secret, but feels she must hide all negative feelings from her husband and appear to him as a happy, supportive wife. This is taking a toll on her, and she is unable to sleep well. She attends a sophisticated party with Korvo, where he has words with one Theresa Randolph, who has clearly had an affair and a bitter breakup with him (and is now Dr. Sutton's patient). Korvo hypnotizes Ann and instructs her to sleep well, which works, but, significantly, he cannot make her obey his order to put her hand in his.
Ann meets Korvo at the hotel where he lives for what she thinks are further therapy sessions, but refuses to go up to his suite and insists on talking in public in the hotel bar. Korvo distracts her and takes the martini glass with her fingerprints on it and her scarf. 
Question: What is the full name of the person who stole a mermaid pin?
Output (English): Ann Sutton.
