Horror, let's face it, is basically pretty dumb. You're writing about events that are preposterous, and the trick is to dress them up in language so compelling that the reader doesn't care.
Imagine (if you dare) a whimsical marriage of Lord Dunsany and S.J. Perelman, and you have something approaching the tales of Rhys Hughes, filled with gaudy colour, slapstick, puns, fantastic creatures, and the occasional unexpected chill. Hughes' world is a magical one - and his language if the most magical thing of all.
