Task: Question Answering
Input (English): Passage: Down-on-his-luck Los Angeles architect and builder Edward Shaw is approached by Doris Hillman with a business proposal: buying land together, on which he would build houses that she would then sell, using her experience as a former real estate broker. Her husband, Gus Hillman, a wealthy businessman, would be willing to contribute half a million dollars as capital for the venture.
Doris quickly seems interested in more than a purely professional relationship. Shaw starts an affair with her and accepts the business offer. However, an accidental discovery leaves him convinced that the Hillmans' interest lies less in the long-term profits of the venture than in the $175,000 key man insurance policy he took on himself as a precondition for the deal, and that an attempt on his life is imminent.
Madge, the younger sister of Doris, develops a romantic interest in Shaw as well. Without knowing what Doris has planned, she reveals to Shaw that her sister was married previously to a man who died in Wyoming when his car crashed over a bridge. Shaw ends up drugged by Gus Hillman and barely keeps his car from going off a cliff.
The police are skeptical about his story and the insurance company refuses to cancel the policy, Hillman having portrayed Shaw as a man who is trying to steal his wife. Madge teams with Shaw to try to foil her sister's scheme, but Doris lures him to a mountain cabin and shoots him with a gun. A wounded Shaw sees both Hillmans struggle then fall to their deaths through a clifftop doorway, just minutes before Madge and the cops arrive. 
Question: What are the first names of the two people who have a romantic interest in Shaw?
Output (English): Madge.
