this job months ago. Meanwhile, Rake stakes out Brian Underhill's apartment in Mechanicsville, until he sees his partner, Dunlow, enter into the apartment. Rake eavesdrops on the two and his suspicion increases. After seeing Dunlow and Underhill enter a brothel called "Mama Dove's" in the African-American part of town, Rake decides to investigate. Mama Dove tells Rake that Underhill often picks up "her girls," and they are never seen again. Rake tails Underhill again and is caught. The pair fight and Rake tries to get Underhill to answer questions about Lily's murder. Unsuccessful, he leaves and hears shots behind him. He then finds Underhill dead. Rake leaves the scene as to not incriminate himself of the murder. Rake visits Silas Prescott, Senator Prescott's son, to ask him some questions about Lily. Silas tells Rake that Lily was fired because she stole something from their family. Rake is tipped off on the phone to meet an unknown caller at a park for information on the murder. When Rake arrives, he is sabotaged by ex-cops that reveal Underhill was part of the "Rust Division," a group that cleans up after murders and crimes committed by high profile individuals. Dunlow hears from Mama Dove that Rake had come to her asking questions about Underhill and Dunlow. A very drunk Dunlow picks up Rake and takes him to his shed where he reveals that he had a child with Mama Dove, who was hit by a car and killed. When Rake goes to leave, Dunlow picks up his gun, whispers the word, "bang," and pretends to shoot Rake. Smith and Boggs go to Peacedale to try and find answers about Lily's murder from her family; and the local officers run the pair out of town. They try to warn the Ellsworth family of the danger they are in, but it is too late. Smith and Boggs are told that the family's house is on fire. Officer Boggs later calls Rake and reveals to him that Lily's mother was previously an employee for the Prescott's and she was taken advantage of by young Senator Prescott in the 20s, resulting in her pregnancy with Lily. Still unsure of who actually murdered Lily, Rake confronts Silas Prescott and Silas reveals that he had sexual relations with Lily, and when he found out she was his sister, he murdered her. Before Rake can arrest him, Silas shoots himself
