The bit where Dunning feels the hairy snout under the pillow is fantastic!

It’s all the more effective for being the only (I think) physical evidence of a malevolent creature at all in the story.

Even then, as you suggest, it is only described in the language of touch and not sight.

In terms of what remains unsaid (as opposed to what remains unseen) the ending is fabulous.

Also, after a judicious interval, Harrington repeated to Dunning something of what he had heard his brother say in his sleep: but it was not long before Dunning stopped him.

The bit where Dunning feels the hairy snout under the pillow is fantastic! I’d have shat myself if I’d read that as a kid. It’d be tough to pull off a scare like that onscreen, as so much depends on the lack of a clear picture.

The demon in Curse of the Demon is pretty laughable [great as the movies is]. The snout is simply terrifying!
