Task: Question Answering
Input (English): Passage: Larry Wilson and Richard Parker are at a Manhattan morgue where they see their deceased CEO Bernie Lomax. Larry falsely claims Bernie as his uncle, so he can get some of Bernie's possessions including Bernie's credit card. At the insurance company, Larry and Richard are quizzed by their boss and Arthur Hummel, the company's internal investigator, who ask the two if they have the US$2 million that Bernie embezzled. They deny knowing where the money is, but their boss believes they're lying and fires them. He also sends Hummel after them, giving him two weeks to prove their guilt.
Over dinner (paid for with Bernie's credit card, in one of its many uses), Larry tells Richard he found a key to a safe deposit box in St. Thomas, U.S. Virgin Islands and asks Richard if he will use the computer at work to see if the $2 million is in Bernie's account. At first Richard refuses but ultimately gives in.
Meanwhile, in the Virgin Islands, a voodoo queen named Mobu is hired by mobsters to find the money Bernie stole. She sends two servants—Henry and Charles (Tom Wright)—to go to New York, get Bernie's body, use a voodoo ceremony to reanimate him, and bring him back to her so he can lead her to the money. Their attempts to bring Bernie back are plagued by accidents. They prepare in a bathroom at a sleazy porno theater for the voodoo ceremony, but having lost the sacrificial chicken, they use a pigeon instead. This limits Bernie's ability to walk toward the hidden money: he only moves when he hears music. At the 42nd St-Grand Central subway station, Henry and Charles soon abandon him to chase a man who stole their boombox. 
Question: What is the name of the person who sends Hummel after Larry and Richard?
Output (English): their boss.
