Sergeant Detritus was recruited to represent an ethnic minority in the Watch, along with Cuddy and Angua. He has since risen up the ranks with the speed of Captain Carrot, becoming a Sergeant in two years. He has an unusual approach to questioning, usually along the lines of, "It was you what done it wasn't it, own up," and can go on patiently asking for hours until the questionee gives in. The only thing that will defeat him is an outright denial. Detritus has shown himself to be a trustworthy officer, and can be quite intelligent, particularly when the temperature is below five degrees.
