There's a lot more going on in "Benighted" than I caught the first time I read it. This time, beneath the gothic elements I was previously distracted by, and which still work marvellously, is an allegory on English post-war society, the rottenness of the class system and the aristocracy, coupled to a demonstration of the levelling and humanising effect of meeting others openly and honestly.
I upped my rating to 5 well-deserved stars.
