Task: Question Generation
Input (English): Passage: Sister Mary Bonaventure is in charge of the hospital ward of a convent in the county of Norfolk, England. She is troubled by her own sister's suicide, which she confides to her Mother Superior.
A torrential rain closes nearby roads, causing Sergeant Melling of the police to bring condemned murderer Valerie Carns there. She is being taken to prison.
Valerie was convicted of poisoning her brother Jason, a pianist. Jason's physician, Dr. Jeffreys, is head of the hospital where Sister Mary now works. Valerie still proclaims her innocence, but Jeffreys insists that she gave Jason a fatal overdose of his medicine.
A photograph of Jason clearly disturbs Isabel Jeffreys, the doctor's wife. He gives her a sedative. Valerie appeals to Sister Mary to bring her fiance, Sidney Kingham, to the convent to see her. A servant tells Sister Mary about the sadistic behavior of Jason Carns and produces a love letter to him, clearly written by Isabel.
Mother Superior is upset by Sister Mary's meddling. She burns the letter. The nun still intends to tell Melling the police sergeant what she knows.
Dr. Jeffreys is the one who gave Jason the fatal dose, and he might be slowly poisoning Isabel as well. He lures Sister Mary to a bell tower, where he attacks her. She rings the bell. Sidney hears it, rushes to her aid and overpowers Jeffreys, who is arrested by Melling.
Sister Mary's faith is restored, believing the rain that delivered Valerie to her to be divine intervention.
Output (English): What is the name of Sidney Kingham's fiance?
