Task: Question Answering
Input (English): Passage: Charles Oakley is living alone in a rooming house. His landlady tells him that two men came looking for him. He sees the two men waiting on the street in front of his room and he decides to leave town. Charlie Newton is a bored teenaged girl living in the idyllic town of Santa Rosa, California. She receives wonderful news: Her mother's younger brother (her namesake), Charles Oakley, is arriving for a visit. Her uncle arrives and at first everyone is delighted with his visit, especially young Charlie. Uncle Charlie brings everyone presents. He gives his niece an emerald ring which has someone else's initials engraved inside. Mr Newton works at a bank and uncle Charlie tells him he wants to open an account and deposit $40,000 at his bank. Two men appear at the Newton home posing as interviewers working on a national survey. Uncle Charlie is upset and berates his sister for opening up her home to strangers. One of the men takes a photo of Uncle Charlie, who demands the roll of film, because "no one takes my photograph." The younger interviewer, Jack Graham, asks young Charlie out, and she guesses that he is really a detective. He explains that her uncle is one of two suspects who may be the "Merry Widow Murderer". Charlie refuses to believe it at first, but then observes Uncle Charlie acting strangely, primarily with a news clipping from her father's newspaper that describes a murder. The initials engraved inside the ring he gave her match those of one of the murdered women, and during a family dinner he reveals his hatred of rich widows. 
Question: What is the full name of the person who guesses someone is a detective?
Output (English): Charlie Newton.
