The Summons by A.E.W. Mason

Between the North and South Downs in the east of Sussex lies a wide tract of pleasant homely country which, during certain months of those years, was subject to a strange phenomenon. Listen on a still day when the clouds were low, or at night when the birds were all asleep, and you heard a faint, soft thud, so very faint that it was rather a convulsion of the air than an actual sound. Fancy might paint it as the tap of an enormous muffled drum beaten at a giant's funeral leagues and leagues away. It was not the roll of thunder. There was no crash, however distant, along the sky. It was just the one soft impact with a suggestion of earth-wide portentous force; and an interval followed; and the blurred sound again. The dwellers in those parts, who had sons and husbands at the war, made up no fancies to explain it. They listened with a sinking of the heart; for what they heard was the roar of the British guns at Ypres.

Into this country Martin Hillyard drove a small motor-car on a day of October two years afterwards. Until this week he had not set foot in his country of the soft grey skies since he had left Rackham Park. He had hurried down to Rackham as soon as he had reported to his Chief, but not with the high anticipation of old days. In what spirit would he find his friends? How would Joan meet him? For sorrow had marked her cross upon the door of that house as upon so many others in the land.
