The Mystic Adventures of Dorian

At four AM two days later, Dorian is rudely awaken by the police knowing on his door. He blearily gets up to answer the door, but they kick it down before he gets there.

Officer Brown and Officer Castro enter his house. Turns out his advertisement has been found in the pockets of five murder victims throughout the city.

Brown and Castro give him the ol' "good cop bad cop routine" and can't seem to decide whether they think he's the murderer, or if they want to ask him for help. All the while they brush aside his requests to see a warrant for entering his home.

How does Dorian respond during their deliberation?
