Task: Question Answering
Input (English): Passage: Eve Gill is an aspiring actress at the Royal Academy of Dramatic Art in London. She is interrupted in rehearsal by her friend (and crush), actor Jonathan Cooper, the secret lover of flamboyant stage actress/singer Charlotte Inwood. Via a flashback, he says Charlotte visited him after killing her husband; she was wearing a bloodstained dress. Jonathan claims he went back to her house for another dress, but was seen by Nellie Goode, Charlotte's cockney maid/dresser. He escaped the police and needs help.
Eve takes him to her father's house on the coast to hide. Commodore Gill notices that the blood on Charlotte's dress has been smeared on deliberately; he and Eve think that Jonathan was framed by Charlotte. Jonathan angrily destroys the dress and thus the most useful piece of evidence.
Eve starts to investigate. She hears Charlotte's dresser Nellie Goode boasting about her new found notoriety in a bar. While she is there, Eve meets Detective Inspector Wilfred O. Smith, and they become friendly. Eve then poses as a reporter; she bribes Nellie to tell Charlotte she is ill and to introduce her cousin "Doris Tinsdale" as a replacement. Using her acting skills, Eve becomes "Doris" and starts working for Charlotte. Eve discovers Charlotte is having an affair with her manager Freddie Williams.
Eve and "Ordinary" Smith become more friendly. When Smith visits Charlotte, Eve has to disguise the fact that she is also "Doris" the maid. Smith makes a courtship visit to Eve and her mother at home, where the commodore drops subtle hints that Jonathan has left the seaside house. 
Question: What is the full name of the person who says that Charlotte visited them after killing her husband?
Output (English): Jonathan Cooper.
