"I do not know, General Luxton," he said, slowly, "what the prisoner can expect me to say likely to benefit him. He can scarcely be so mad as to expect me to shield him in this matter on account of our relationship, or to preserve the honour of our name, and yet I do not see why else he should have appealed to me. I saw very little of the affair, and would rather not have seen that. I was riding to you, sir, with a message from Colonel Elliott; and, as I passed trench 4, I saw the prisoner suddenly leave his company and run towards me. He passed several yards to the left, and as he seemed to be hurrying along aimlessly, I called to him. He made no answer, but——"

"LIAR!"

The word seemed hurled out with such a passionate intensity that every one started. General Luxton looked up angrily.

"Silence, sir! You will have an opportunity of saying what you have to say presently. Proceed, Devereux."

"As I was saying," Rupert Devereux continued calmly, without appearing to have noticed the interruption, "he made no answer, but seemed to wish to avoid me. As the message with which I was entrusted was an important one, I rode on and left him hurrying towards the rear."

With a sterner air even than he had at first assumed, General Luxton turned towards the unfortunate young man who stood before him. He was standing as though turned to stone, with wide-open eyes, staring at the man who had just spoken, attitude and expression alike bespeaking an overpowering bewilderment.

"You are at liberty to ask the witness any questions," the General said, shortly.

For a moment there was a dead silence. Then the words came pouring out from his quivering lips like a mountain torrent.

"Rupert, what have you said? What does this mean? Good God, are you trying to ruin me? Did I not run to your assistance because you were beset by those three blackguards? Didn't I kill two of them and save your life? You can't have forgotten it! Why are you lying? Hilton saw it all, and so did Fenwick. Where are they? My God, this is horrible!"

The deep flush had gone from his cheeks, and left him pale as death. Great beads of perspiration stood out upon his forehead, and there was a wild look in his deep blue eyes. But the man to whom he made his passionate appeal kept his back turned and heeded not a word of it. Instead of answering he addressed the General.
