A Duke, disguised as a woman or priest, landing at night; a dark man stealing documents from a tapestried chamber of some castle, where bats and cobwebs shared the draughty corridors--such scenes were incomplete unless a Night-Wind came in audibly at critical moments. It wailed, moaned, whistled, cried, sang, sighed, soughed or--sobbed. Keyholes and chimneys were its favourite places, but trees and rafters knew it too. The sea, of course, also played a large part in these adventures, for water above all was the element Uncle Felix loved and understood, but this Night-Wind, being born at sea, was also of distinct importance. The sea was terrible, the wind was sad. To the children it grew more and more distinct with each appearance. It had a personality, and led a curious and wild existence. It had privileges and prerogatives. Owing to its various means of vocal expression--singing, moaning, and the rest--a face belonged to it with lips and mouth; teeth too, since it whistled. It ran about the world, and so had feet; it flew, so wings pertained to it; it blew, and that meant cheeks of sorts. It was a large, swift, shadowy being whose ways were not the ordinary ways of daylight. It struck blows. It had gigantic hands. Moreover, it came out only after dark--an ominous and suspicious characteristic rather. "Why isn't there a day-wind too?" inquired Judy thoughtfully. "There is, but it's _quite_ a different thing," Uncle Felix answered. "You might as well ask why midday and midnight aren't the same because they both come at twelve o'clock. They're simply different things." "Of course," Tim helped him unexpectedly; "and a man can't be a woman, can it?" The Night-Wind's nature, accordingly, remained a mystery rather, and its sex was also undetermined. Whether it saw with eyes, or just felt its way about like a blind thing, wandering, was another secret matter undetermined. Each child visualised it differently. Its hiding-place in the daytime was equally unknown. Owls, bats, and burglars guessed its habits best, and that it came out of a hole in the sky was, perhaps, the only detail all unanimously agreed upon. It was a pathetic being rather. This Night-Wind used to come crying round the bedroom windows sometimes, and the children liked it, although they did not understand all its melancholy beauty. They heard the different voices in it, although they did not catch the meaning of the words it sang. They heard its footsteps too. Its way of moving awed them. Moreover, it was for ever trying to get in. "It's wings," said Judy, "big, dark wings, very soft and feathery." "It's a woman with sad, black eyes," thought Tim, "that's how I like it."
