Cleon's onslaught was exactly like that of a wild beast. It was a yell and a spring, and it would in all probability have been fatal to Ducie had not the latter been fully prepared for something of the kind. But the very instant Cleon sprang at his throat, out went Ducie's right arm, straight and true, like a sledge hammer, full in the mulatto's face. Cleon dropped before it as though he had been shot through the brain. But next instant he was on his feet again, his face streaked with blood, and now looking more ghastly than before. He said something Ducie could not understand, but if murder ever lurked in a man's eyes, it peeped out of the mulatto's at that moment. He was not at all daunted by his mishap: only rendered more wary. He made several feints and false moves before he ventured on a second dash at the captain. At last he thought he saw his chance, and in the twinkling of an eye he had struck his dagger into the captain's shoulder. He had aimed at the heart, but his enemy had proved too quick for him. His dagger pricked into Ducie's shoulder, and Ducie's arms went round him like a vice. The mulatto was active and sinewy, but in a close struggle he was no match for the great strength of his opponent. His arms were pinned to his sides, but his head was at liberty, and with his long sharp teeth he fastened on Ducie's cheek and bit it through. This roused Ducie's blood as half a dozen pricks with the dagger could not have done. Lifting Cleon bodily up, he swung him once round, and then dashed him with all his might against the side of the cave. The mulatto rebounded from the rock, and came to the floor with a dull heavy thud. He groaned twice, and then all was still except the heavy beating of Ducie's heart.

Ducie bent over the body for a moment. "His fate be on his own head!" he muttered. Then, having made sure that the Diamond was still safe in his possession, he took up the lamp and passed out of the cave. He shut and locked the two doors behind him, and when he got back to the library he also closed the secret door through the bookcase. As he passed through the smoke-room he gave one hasty shuddering glance at the dead body of Platzoff. The half-open eyes seemed to fix him with a look of terrible reproach. He fancied that he saw the pallid lips move. "Ingrate!" they seemed to say, "was it for this I took thee to my bosom and called thee friend?"

Ducie put his hand to his eyes and strode on. He found the door that led into the corridor half open as it had probably been left by Cleon in the horror of the sudden discovery he had made on entering the smoke-room. Ducie closed it carefully behind him. That door locked up a double secret, and it behoved him to get clear away from Bon Repos before it could be brought to light. He carried his treasure with him, and that would compensate for everything.

The moment he turned into the corridor to go towards his own rooms he began to feel faint from loss of blood. The first great excitement was over, and now his wounds began to make themselves felt. Great heavens! if he were to lose his senses at such a critical moment and be found by the servants! They would perceive that he was wounded, and would probably strip him, and then how would it fare with the Diamond? Just as this thought was in his mind Jasmin came suddenly round a corner and started back in alarm at sight of his pale face all streaked with blood.

"Sir--Captain Ducie--what is the matter? Are you wounded?" he cried.

"A slight accident--a mere scratch," gasped the captain. "Lend me your arm as far as my room, and--and don't leave me yet awhile."

The first message sent by the telegraph clerk at Oxenholme station when he went on duty next morning, was as under: "From J. M., Windermere, to Solomon Madgin, Tydsbury, Midlandshire.

"Address no more letters to B.R. till you hear from me again. A grand fracas. The Captain and I are on our way to town. Unless I am greatly mistaken, we carry the G.M.D. with us."
