Who Could That Be at This Hour?
At the beginning of Who Could That Be at This Hour?, Hangfire is said to be hiding out in Stain'd-by-the-Sea. When Lemony Snicket and S. Theodora Markson arrive at the Sallis Mansion, Hangfire is disguised as a butler. He is good at imitating the voices of others, as he imitates the voices of Lemony Snicket, Ellington Feint, Moxie Mallahan, and Mr. Mallahan. He has captured Ellington Feint's father (Armstrong Feint), and told her that she will never see him again.
In order to get his hands on the Bombinating Beast, he first sends a telegram to the Mallahans, requesting to buy it. When this plan fails, he hires Dame Sally Murphy to work for him and nearly drowns her in the basement of the Sallis Mansion. She, however, says that "he" referring to Hangfire, is the only person who can help her. He also hires Lemony and Theodora to steal the Bombinating Beast from the Mallahans at the request of Dame Sally Murphy. After Prosper Lost foolishly allows him to enter the Far East Suite, he ties S. Theodora Markson to her bed in The Lost Arms. She says that he tells her he is going to kill her, and then depicts him as terrible, despicable, and loathsome.
Near the end of the book, Ellington reveals that she has been tracking Hangfire for sometime, and he has kidnapped many people in order to get what he wants, including her father. Ellington makes off with the Bombinating Beast in search of him.
