Dazed and frightened, as after a hideous nightmare, he pulled himself together. The match he had taken up was still in his hand, and he turned back, mastering himself with a great effort, to his patient.

He lighted the big burner and turned it full on the chair. The man, roused from the lethargy of morphia, slowly opened his eyes.

Armstrong staggered back, stifling the cry of horror that rose to his lips; for in that one glance he saw, clear and unmistakable, the face of his torturer—reincarnated, but still the same.

IV.

Armstrong turned aside to hide his excitement. After all, then, the vision had not been in vain: it was the complement of the first; and now all was clear. The Mystery of Human Pain! His own great book on the subject! He laughed aloud. All that thought and time and labour had been wasted, and here was the truth, shown to him in a dream—the truth that all the world should know. A strange exaltation filled his spirit.

I suffered pain, and now I reap my reward—strong, happy, a healer of wounds, myself knowing no suffering. He inflicted pain and torture, and now he suffers for it.”

The patient in the chair moved uneasily and groaned. Armstrong went on: “A righteous Judge rewards me for what I have undergone, and scourges him for the evil he has wrought.”

“The Lord have Mercy on his Soul!”

It was a deep voice that spoke, the words booming and reverberating like the notes of heavy bells. It touched a new chord in Armstrong’s mind, and sent the blood throbbing and pulsing through his head. “The Lord have mercy on his soul!” Why? What mercy had he had for others? And with that the fury of hate returned to him and surged through his veins, till he felt himself more demon than man. Every pang, every pain, every racking agony that he had suffered in those two terrible visions, returned to him threefold, burned into his soul, branded on every limb and sinew. Curse him with the curse of the martyr, and blast him with the breath of his iniquities!
