In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: Billy Behan is a poor teenage boy from the Bronx.  One day he catches the attention of gangster Dutch Schultz.  Changing his last name to Bathgate, after a local street, he goes to work for Schultz's organization, serving mostly as a gopher for Schultz.  Billy is present when Schultz murders his former partner Bo Weinberg, who Schultz believes betrayed him. Schultz then begins a relationship with Weinberg's beautiful, married, girlfriend, Drew Preston.
Facing legal charges in a court in upstate New York, Schultz brings Billy and Drew along.  He successfully charms the locals, presenting himself as charming and good natured.  While his boss Dutch stands trial, Billy's job is to watch over Drew.  His loyalties to Schultz are tested as he begins falling in love with the flirtatious Drew. Realizing that Drew is about to be killed, Billy calls her husband, who hurries to town and takes her home before Schultz's men can make their move.
Having beaten the rap in court, Dutch is indicted again on federal tax evasion charges.  He wants to have federal prosecutor Thomas Dewey murdered, but his request is rejected by the Mafia Commission.  Schultz sends Billy to another gangster with some bribe money, but the effort is rejected.  When Billy returns with the bad news, he and Schultz have a falling out and Billy is fired by Schultz's associate Otto, who lets him keep the bribe money as a severance package.  As Billy leaves, he is abducted and beaten by gangsters working for Lucky Luciano.  The men storm Dutch's hideout and kill everyone inside.  Billy is taken before Luciano, who warns him that he knows where Billy's family lives, before letting him go.
A:
What is the first name of the person who places the call to Drew's husband before she can be murdered?
