The following article contains an answer for the question: Where does Mr. Slade work? , can you please find it?   In New York City, 1934, jazz singer Dot Clark and her shady gangster boyfriend, Louie The Lug ("An Earful of Music"), are introduced. After having an affair with the deceased Professor Edward Wilson, Dot is now technically his common-law wife and heiress to $77 million. She has to go to Egypt to claim the money, and sets off with Louie in hopes of getting the cash. Former assistant to Edward Wilson, Gerald Lane, informs the law offices of Benton, Loring, and Slade of Professor Wilson's death and the fact that Edward's son, Eddie Wilson, Jr, is the rightful heir to the money. Mr. Slade, the lawyer, goes to a barge in Brooklyn where Eddie is living with his adopted father, Pops, an old stevedore, and his three sons, Oscar, Adolph, and Herman, who roughhouse Eddie. However, Eddie is managing to live a nice life nonetheless, with his girlfriend, Nora 'Toots', and his care for all the kids on the barge. He dreams of the day when he will have enough money to live his own life outside of the dirty barge ("When My Ship Comes In"). Moments later, Eddie is informed that he has inherited the $77 million and boards a ship bound for Egypt to claim the money. Aboard the ship is Colonel Henry Larrabee, a gentleman from Virginia who sponsored Eddie, Sr's exploration endeavors and wants a share of the money, as well. Eddie befriends his beautiful niece, Joan, and Dot and Louie realize that they are not the only ones traveling to Egypt. In an elaborate scheme to trick Eddie into signing over the inheritance, Dot disguises herself as Eddie's mother and almost succeeds in duping him, but Louie ruins the plan at the last minute. Meanwhile, Gerald Lane has boarded the ship and  he is revealed to be in love with Joan Larrabee.
