Time out. OK, what is the right way to form an adjective based on Evelyn Waugh's name? "Waughian" won't do. Perhaps add a "v," on analogy with Shaw --> Shavian? We'll go with that.
...Wauvian (looks peculiar, but I'm sticking with it), especially the Waugh on Vile Bodies and A Handful of Dust, hilarious and chilling, laughter with a bleak, frozen wasteland at its core.
