When Carrot tries to find that truth, however, he is shown a body that was mutilated after death, and a confusing patch of clues. Angua discovers that a troll really "was" in the mine at the time of the murder, much to the consternation and fear of the dwarves who claimed a troll did the killing. This troll turns out to be Brick, who is a gutter troll of the lowest sort, addicted to Troll drugs beginning with "S," (such as Slab, Scrape, Slice, Slide etc.) and who becomes the protégé of Sergeant Detritus.
