One does not recover from sunstroke in a little, and in most cases it leaves a permanent mark behind it. Sangster was no exception to the rule. For weeks he lay between life and death. There were times when he tottered on the brink of that dark precipice, down which we must all go sooner or later; but he rallied at last. Finally he was well enough to travel, and the sick man came home. He had never mentioned to a soul what he had done at Shah Doula's Pool. If he had spoken of it during his illness, it was doubtless set down to the ravings of delirium. When at length he recovered his senses, he could only recall what had happened to him in a vague manner. But he was no longer his own cheery, somewhat noisy self. He was listless, moody, and apathetic. Over his mind there seemed to brood a shadow that would take to itself neither form nor substance, and against which he could not battle. The doctors said the long sea-voyage home would set him right in this respect. They were wrong, and day after day the man lay stretched on his cane deck-chair, or paced up and down in sullen silence, exchanging no word with his fellow-passengers. At last they reached Plymouth, and although it was seven years since he had left England, he never even glanced out of the windows as the train bore him to his Berkshire home. He arrived at last and was made much over. Kind hands tended him, and loving hearts were there to anticipate his slightest whim. It was impossible to resist this, and in a little time the clouds seemed to roll away from his mind, and he was once more gay and bright. One warm sunny day, as he was lying in a hammock under the shade of a sycamore, hardly conscious that he was awake, and yet knowing he was not asleep, his mind seemed to slip back of its own accord into the past. In an instant the soft turf, the mellow green trees, the restful English landscape faded away. A wind that was as hot as a furnace blast beat upon him. All around was a dreary waste, and above, the sky was a cloudless, burning blue. He was once again holding in his fiery Arab, and listening to the curse hissing out from the lips of the devotee. He almost heard the blood dropping from his spear on to the grey dust below his horse's hoofs, and from the heart-shaped _peepul_ leaves--it was no longer a sycamore he was beneath--the whistle of the green pigeon came to him soft and low. A strange terror seized him. He sprang out of the hammock. He had not been asleep. It was broad daylight, and yet he could have sworn that for the moment time had rolled backwards, and that he was eight thousand miles away from the square, red brick parsonage, in the firwoods of Berkshire. And then he began to understand.
