"Was that fair fighting, yellow man?" he asked.

"No," laughed Brian. "It was unfair, Cathbarr; but I think my fists can best your ax yet."

Slowly the giant got to his feet. To Brian's surprise he left his ax where it lay and came forward with extended hand.

"Had you claimed that blow as fair," he rumbled, "I would have slain you. Now I love you, yellow man. Let us make a pact together. What is your name?"

They struck hands, and Brian felt a great thrill of admiration for this man whose terrible strength enclosed the simple heart of a child. But he shook his head.

"I make no pacts, Cathbarr. My name is Brian Buidh. I made pact with the Dark Master, and now I am sorry for it; yet it must be held to, for I see no way out of it. But wait—I have a cunning man whose wit may help us here."

He turned and flung up his sword in the air. His men rode down to the narrow causeway, while from the tower came shouts warning Cathbarr against treachery. But the giant only grinned again, and Brian shouted to Turlough Wolf to come on alone.

Old Turlough obeyed in no little wonder. When he came up Brian told him what had chanced—that out of enmity had arisen friendship.

"But," he concluded, trouble in his heart, "you must find me a way out, Turlough. I have passed my word to O'Donness to reduce Cathbarr; to do that I must slay him, or he me. I see little honor either way."

"Few men find honor in their dealings with the Dark Master," grumbled Turlough, looking from Cathbarr to Brian. "Yet, if you want a way out, it is an easy matter. Cathbarr of the Ax, give service to my master. Thus, Brian Buidh, you shall reduce Cathbarr; yet the Dark Master said naught of giving up this man to him."
