"Yes," said the Colonel slowly, "but this does not mean common garrotters. The fact that they stole nothing really disposes of that. This means a much darker and more terrible business."

"And what is that?" cried the headmaster.

"Thuggee," said Colonel Keppel very gravely.

"Thugs, Colonel!" said Dr. Lawrence in a tone of stupefaction. "Are you serious? Thugs on the heath here, in our quiet, familiar country?"

"This is a Thug noose, at any rate," said Colonel Keppel. "I know it very well. I served twenty-seven years among the hill-tribes of northern India in one capacity and another, and once I served in a Thug country, and I shall never forget it. The way young Haydon was handled suggests Thuggee. No common garrotter could have overcome such a fine, powerful young fellow in that fashion. But the skill of these Thugs is a thing truly diabolical. I remember one instance well. One night, just upon dusk, two men of my regiment were entering the gate of the cantonments. The guard saw them pass, and one was relating a story to the other. The man telling the story expected his comrade to laugh at the conclusion of the anecdote. Hearing nothing, he turned and found that he was walking alone and talking to the empty air. Thinking his comrade had slipped aside and played a trick upon him by leaving him to himself, he went on to the barrack-room. Later the second man was missing, and inquiries were made. A search followed, and the dead body of the unfortunate man was found under the wall of the cantonments. He had been seized and strangled by Thugs when actually walking beside a comrade, and the latter had known nothing of it.

"That shows frightful skill and cunning, Colonel," said Dr. Lawrence.

"It does indeed," said the other, "and I could relate a dozen such stories. But why Thugs should be here and attack Haydon seems a most extraordinary mystery. How do you feel now, Haydon?"

"Much better, sir," replied Jack. "My throat's a bit stiff, but for the rest I am none the worse."

"You've had a wonderful escape, my boy," said Colonel Keppel; "there are not many who have felt a Thug noose and lived to say what it was like. But now, Doctor, what are we to do? There must be some inquiry made into this."

"Of course, of course," agreed Dr. Lawrence. "You are a magistrate, Colonel; what do you recommend?"
