"Murdering all those Emmetts had been especially hard on Archibald who was never adept at taking the lives of non-gazelles, however plentiful those lives might be. He grew more and more ill as the Emmetts came and dropped. He became increasingly fearful of silence and the dark, spending hundreds in oil to keep the house bathed in flickering light, a whole house drowning in amber. He’d taken to leaving tarpaulins up on the walls for when the Emmetts arrived so he could minimize his cleanup time, but as he spiraled deeper into paranoia he neglected to scrub them, and they wriggled blackly with flies. With an eye to hygiene, he had once tried strangling an Emmett, but this had proved too horrific for him to bear."
