Task: Question Answering
Input (English): Passage: Bob Weston works for STOP, a scandal magazine whose owner and staff are proud of being regarded as the filthiest rag in America. One of Bob's colleagues has just written an article about Dr. Helen Gurley Brown, a young psychologist and author of the best-selling book Sex and the Single Girl, a self-help guide with advice to single women on how to deal with men. The article raises doubts on her experience with sex and relationships. Helen is very offended, having lost six appointments with patients due to the article discrediting her as a "23 year-old virgin.". Bob wants to follow up by interviewing her, but she refuses.
Bob's friend and neighbor, stocking manufacturer Frank Broderick, is having marriage issues with his strong-willed wife Sylvia, but can't find the time to go to a counselor. Therefore, Bob decides to impersonate Frank and go to Helen as a patient, with the goal of getting close to her in order to gather more information. In exchange, he'll report back to Frank her advice. During their first couple of sessions, Bob acts shy and smitten, and tries to gently seduce Helen. She seems to respond to Bob's courteous advances, all while insisting it's a transfer and that she'll play the role of Sylvia to the benefit of his therapy. After he fakes a suicide attempt, the two of them end up making out in her apartment, with Bob realizing he's actually falling for Helen, which is the reason he still has not written anything about her, prompting an ultimatum from his boss. 
Question: What is the last name of the person Helen pretends to be in therapy sessions?
Output (English): Broderick.
