After some fifteen happy years his wife died, very suddenly. No man ever mourned his dead more truly; but it was inevitable that when the first pangs of bereavement died into a dull aching, he should long to resume his wandering life. Some special studies, which he had been making when the great calamity overtook him, gave definiteness to his plans. His fancy had been caught by the old legend of Agbar, King of Edessa, of his letter to our Lord, and the answer, fabrications though they manifestly are. An idea possessed him that in the neighbourhood of the ancient Edessa, Agbar's "fair little city," so early Christianized, MSS. might be found, dating perhaps from the first century. The thought gave an object to his proposed wanderings in the East, for to the East his heart was ever drawn by strong, mystic yearning. And if his dreams should prove only dreams, there was no duty now which forbade him to pursue them. One duty indeed he had--the care of his boy. Always much attached, in the days of their bereavement son and father drew very close together. Everybody advised him to leave Jack at school, but everybody spoke to deaf ears; for Jack entreated him to take him with him, and his own heart echoed the plea. After all, why not? He was a strong, healthy lad, very manly, and full of bright intelligence. Might not foreign travel be the best of schools for him? To Jack the prospect seemed the most delightful ever unfolded before mortal eyes. Grayson could well afford every luxury of travel that might ensure safety and preserve health. Had he been alone, he would have cheerfully faced many risks and inconveniences to which he did not care to expose his son. So far they had journeyed in great comfort, keenly enjoying the adventure. They expected next morning to reach a little town on the Euphrates called Biridjik, where they proposed to rest for a day or two, arranging, as they always did in such circumstances, for the use of a room or rooms in some comfortable house. The journey by night, in that land where night never means darkness, was delicious. The moon was at the full, and bathed in beauty even the desolate, monotonous landscape. Its light was quite enough for all travelling purposes; it seemed indeed only a softer, cooler, and more genial day. Early morning found them on the stretch of road leading to the river. At the other side was a sort of natural amphitheatre. A picturesque hill rose in terraces from the river, near its summit the ruins of a castle. A semi-circular wall, which had once belonged to the castle, formed a bow, of which the river was the string, and which enclosed the little town with its houses, orchards, and gardens.
