Task: Question Generation
Input (English): Passage: En route to California to prospect for gold, ex-sheriff Hooker, professional gambler Fiske, and bounty hunter Luke Daly are forced to stop over in a tiny Mexican village by engine trouble on the ship they are taking. A desperate Leah Fuller hires the three men and local Vicente Madariaga, to rescue her husband, John, who is pinned under debris from a gold mine cave-in in hostile Apache territory.
During the harrowing journey, Luke tries to force himself on Leah late one night, forcing Hooker to intervene. Leah tells Hooker that where her husband is trapped, once was a boom town, but a volcano eruption wiped it out, leaving only a church steeple and the mine uncovered by lava. The resident priest called it the "garden of evil". The Indians now consider the volcano sacred. The group then arrives at the mine. They find John unconscious, and they free him.
Before John wakes up, Hooker sets the man's broken leg.  When John regains consciousness, he accuses Leah of using him to get gold. Hooker talks to Leah later, about what her husband said; after he tells her that he has spotted signs of Apaches nearby, she offers him and the others all the gold they have dug up to take her husband away that night, while she remains behind to make it look like they are all still there. The cynical Fiske unexpectedly offers to stay with her, but when he asks her what he is to her, she tells him, "you're nothing at all, just nothing.".
Output (English): What is the last name of the person whose actions forced Hooker to intervene?
