Right Ho, Jeeves by P. G. Wodehouse

I don't know why it is, but there's something about the rural districts after dark that always has a rummy effect on me. In London I can stay out till all hours and come home with the milk without a tremor, but put me in the garden of a country house after the strength of the company has gone to roost and the place is shut up, and a sort of goose-fleshy feeling steals over me. The night wind stirs the treetops, twigs crack, bushes rustle, and before I know where I am, the morale has gone phut and I'm expecting the family ghost to come sneaking up behind me, making groaning noises. Dashed unpleasant, the whole thing, and if you think it improves matters to know that you are shortly about to ring the loudest fire bell in England and start an all-hands-to-the-pumps panic in that quiet, darkened house, you err.

I knew all about the Brinkley Court fire bell. The dickens of a row it makes. Uncle Tom, in addition to not liking burglars, is a bloke who has always objected to the idea of being cooked in his sleep, so when he bought the place he saw to it that the fire bell should be something that might give you heart failure, but which you couldn't possibly mistake for the drowsy chirping of a sparrow in the ivy.
