"You will perceive," said he, "I have no sword."

But now that the thing was said Muckle John appeared greatly put about and anxious to smooth it over. He shrugged his shoulders and fiddled with the brooch upon his plaid.

"Tuts, Dr. Cameron!" he said. "I spoke over warmly."

But Cameron only frowned and shook his head.

"I have no sword," he said again.

There was no mistaking his meaning. With a shrug Muckle John turned and left the cave.

"Do not fight him, doctor," broke in Rob. "It is sheer madness. Oh, how could ye fall into such a trap? It is to kill you he led you on."

"Rob," replied Cameron, "you are too young to understand the ways of a Highland gentleman."

"But surely you are more service to the Prince..."

"Whisht, boy! Dinna haver. Ye heard what word he used. A man's name means mair than a whole clan of Princes."
