I feel like I "rediscover" Roald Dahl's adult fiction every few years and am always shocked anew at how dark and disturbing much of it is. I'm not sure why, considering it's the same guy who came up with Charlie and the Chocolate Factory and The Witches. These stories are every bit as twisted as their children's counterparts, but more importantly, well-plotted and featuring last-second twists that put a perfect bow on everything that came before.
