Task: Question Answering
Input (English): Passage: When Brooklyn burlesque showgirl Maisie Ravier arrives at a small Wyoming town, she finds her new employer has folded after a single performance, leaving her stranded and nearly penniless. She persuades Rico to hire her for his midway shooting gallery.
Her first customer is the unfriendly "Slim" Martin, the manager of a ranch. Slim accidentally drops his wallet full of money. Rico picks it up and leaves town. Slim has Maisie arrested for theft, but when a search finds she only has 15 cents, he admits his mistake. The deputy sheriff informs Maisie that as a vagrant, she must leave town by midnight, so she hides in the back of Slim's truck. When Slim returns to the ranch, he is displeased to discover the stowaway.
He has Maisie driven to the railway station the next morning. Maisie meets the ranch owners, Cliff and Sybil Ames, who arrive on the train. Maisie fast-talks herself into being hired as Sybil's maid. The Ameses are trying to rebuild their marriage after Cliff discovered Sybil's extramarital affair with Richard "Ray" Raymond.
Maisie's warm personality gradually overcomes Slim's hostility. Slim's demeanor is the result of past hard luck: he confessed to embezzlement to protect his girlfriend and spent a year in prison, only to discover after his release that she had run off with another man. Maisie also becomes friends with Cliff.
Maisie and Cliff volunteer to drive needed supplies to the old ranch house but their car overturns and Cliff is pinned under the wreck. Maisie limps to the house and walks in on Sybil kissing Ray Raymond. Maisie sends the ranch hands to rescue Cliff, who is not seriously injured. 
Question: What happened to the shooting gallery owner's girlfriend?
Output (English): she had run off with another man.
