Task: Question Generation
Input (English): Passage: American Paul Banner used to be a reporter working in London. Recently leaving his paper, he has gone freelance, so that he can focus more on chasing down facts and selling his stories once he gets them. He has no regrets in leaving his job as there will be no more deadlines or misguided editors to divert his attention. He starts up a news agency, Banners Agency, whose motto is "ferret out the facts and sell them to the highest bidder."
When showgirl Nina Duke is murdered, the press are all harrying the police for statements and facts but Banner hangs back and does a little work of his own to uncover the story. Nina, it transpires, was previously in jail for blackmail, so it is possible that this was why she was killed. Banner initially falls for the affections of rival reporter Pam Barnes, but his true affections lie with his secretary, Maxine (Hazel Court. 
A race to find the killer has Banner trying to get the story that the police cannot.
Output (English): What crime did the showgirl once commit?
