Harry Burton was one of the cleverest officers in the Indian police; he was a few years over thirty, a dark-complexioned man of medium height, very agile and powerful, and was known to the Salt Range natives as Koj (tracker) Burton Sahib, owing to his smartness in following up the slightest clue.

Burton, at the Doctor's request, went to occupy Mark's empty tent for an hour or two, and as he stretched himself on the camp bed his busy brain was engaged in trying to form a connection between the broken slab and Mark's absence, and these thoughts kept him awake, so he was the first to hear the footsteps of an approaching horse.

"Hello! Is that you, Ellison?" greeted Burton, as the new arrival dismounted.

"Yes. I heard at Gunjyal about Mark, so, instead of waiting for daylight, I hunted up a horse, and, by all this shouting, I conclude Mark is still missing," said Tom, and in a very few minutes he had related to Burton and the Doctor his experience in the train and what he had learnt in Lahore.

"Ah, things are getting a bit more complicated," said Burton aloud, and then muttered to himself, "But I begin to get a better hold of the idea."

"Now you clearly understand me," said Burton when instructing the headmen. "You are to send out every available man and boy from your villages, and they are to search every nullah until they meet the men from the next village. We think the young Sahib has met with an accident, and if you find him you are to send word here immediately; and you, Appoyas, instruct your men to be most careful in searching those cliffs near your village."

"What's that man's name?" asked the Doctor as soon as the men had gone.

"Appoyas. It is an unusual name—certainly not a Punjabi one," replied Burton.

"I never heard the name before. He is a fine-looking man," remarked the Doctor.

"And a very wealthy man, according to report. That is his village on the very edge of those cliffs about a mile away. It is the most prosperous village on the Salt Range, and celebrated for its stamped-cloth work. Appoyas and his brother Atlasul—another uncommon name—buy up all the cloth made and stamped in the place, and give a good price too, and their camels frequently go off laden with bales. But come over here a minute," and Burton led the Doctor some short distance from the camp.
