A spark glittered near, a spark that towered and hovered overhead, and burst into coiling volumes of lurid smoke with a moving heart of flame. Light broke on a neighbouring hill that had been unseen and forgotten; the hill was crowned with fantastic trees that danced, and a wavering tower. From our own valley below there came a vicious tearing that gave me a momentary chill (so sounds a stream of machine-gun lead, going over), and a group of coloured stars expanded over us. Their bright light showed the night reticulated with thin lines of smoke, like veins of calcite in a canopy of black marble. Our immediate country, pallid and tremulous, faded again, but in that brief prospect of a shadow land I glimpsed a road, the presentment of the long road to Bapaume. So the Bapaume road showed at night by inconsequential and unexpected lights. That hill-crest of leaping trees could be the ridge of Loupart with its wood, and Achete in flames beyond. The notion gave me enough of our hill top. I descended from it. There is a public-house at the foot of the hill, and a lane of harsh noises and a beam of light projected together from its open door across the road. Beyond it I turned into a house, for I knew I should find there an aged and solitary man who would have his own thoughts on such a night as this; for he had a son, and the spectre of the Bapaume road had reminded me where that boy was celebrating whatever peace he knew. His father was not communicative; and what could I say? He sat, answering me distantly and austerely, and he might have been a bearded sage seeing in retrospect a world he had long known, and who at last had made up his mind about it, though he would not tell me what that was. Outside we could hear revellers approaching. They paused at our door; their feet began to shuffle, and they sang: "If I catch you bending, I'll turn you upside down, Knees up, knees up, Knees up, knees up, Knees up, Father Brown." XXVII. The Real Thing JANUARY 9, 1920. There was a country town of which we heard wonderful tales as children. But it was as far as Cathay. It had many of the qualities that once made Cathay desirable and almost unbelievable. We heard of it at the time when we heard of the cities of Vanity Fair and Baghdad, and all from a man with a beard, who once sat by a London fire, just before bedtime, smoking a pipe and telling those who were below him on the rug about the past, and of more fortunate times, and of cities that were fair and far. Nothing was easier for us then than to believe fair reports. Good dreams must be true, for they are good. Some day, he said, he would take us to Torhaven; but he did not, for his luck was not like that.
