I tried the other arm and sat up. The muffled figure in front ran in great striding leaps along the beach, and Moreau followed her. She turned her head and saw him, then doubling abruptly made for the bushes. She gained upon him at every stride. I saw her plunge into them, and Moreau, running slantingly to intercept her, fired and missed as she disappeared. Then he too vanished in the green confusion. I stared after them, and then the pain in my arm flamed up, and with a groan I staggered to my feet. Montgomery appeared in the doorway, dressed, and with his revolver in his hand.

"Great God, Prendick!" he said, not noticing that I was hurt, "that brute's loose! Tore the fetter out of the wall! Have you seen them?" Then sharply, seeing I gripped my arm, "What's the matter?"

"I was standing in the doorway," said I.

He came forward and took my arm. "Blood on the sleeve," said he, and rolled back the flannel. He pocketed his weapon, felt my arm about painfully, and led me inside. "Your arm is broken," he said, and then, "Tell me exactly how it happened--what happened?"

I told him what I had seen; told him in broken sentences, with gasps of pain between them, and very dexterously and swiftly he bound my arm meanwhile. He slung it from my shoulder, stood back and looked at me.

"You'll do," he said. "And now?"

He thought. Then he went out and locked the gates of the enclosure. He was absent some time.

I was chiefly concerned about my arm. The incident seemed merely one more of many horrible things. I sat down in the deck chair, and I must admit swore heartily at the island. The first dull feeling of injury in my arm had already given way to a burning pain when Montgomery reappeared. His face was rather pale, and he showed more of his lower gums than ever.

"I can neither see nor hear anything of him," he said. "I've been thinking he may want my help." He stared at me with his expressionless eyes. "That was a strong brute," he said. "It simply wrenched its fetter out of the wall." He went to the window, then to the door, and there turned to me. "I shall go after him," he said. "There's another revolver I can leave with you. To tell you the truth, I feel anxious somehow."

He obtained the weapon, and put it ready to my hand on the table; then went out, leaving a restless contagion in the air. I did not sit long after he left, but took the revolver in hand and went to the doorway.
