Task: Question Generation
Input (English):  A mysterious millionaire, Raffles Haw, comes to reside in Tamfield in Staffordshire. Even before he arrives, people start gossiping about him. As his house is being constructed, people wonder at the number of workers, their speed, and the complete disregard for the amount of money spent. When Haw arrives, he acquaints himself with the McIntyre family, which consists of Robert, his sister Laura, and their father. McIntyre senior had been a prosperous gun merchant, but has gone bankrupt and lost his sanity. Laura is engaged to Hector, the son of the vicar, Mr. Spurling. Hector is a sailor who is summoned for Naval duty at the beginning of the novel.
Disregarding McIntyre senior as a greedy beggar, Haw sets about to alleviate the misery of the people of Tamfield through the agency of the McIntyre siblings and Mr. Spurling. He saves many families and businesses with his timely financial succour. He has limitless funds, due to having discovered a process to turn lead into gold.
With the passage of time, he becomes disillusioned because his philanthropic activities though they improve the situations of the recipients don't improve the recipients themselves. Instead of becoming better citizens, most become parasites reliant upon alms from the millionaire. Despondent, he seeks the counsel of his fianc e, Laura McIntyre, the one person he supposes to be true to him. Unbeknownst to him, Laura has accepted his proposal of marriage without ending her previous engagement to Hector Spurling. As Raffles and Laura are talking, Hector enters the room, his service having ended earlier than expected. When Raffles discovers Laura and Hector are still engaged, he is heartbroken. The fallen millionaire locks himself in his laboratory, destroys his equipment and his immense fortune, and later is found dead. The process that he used to build his fortune is unrecoverable.
Output (English): Who is the vicar's son engaged to in the story?
