Ulf grasped his hand with a cry of surprise, and led him to the cabin.
"The crew is ashore, but it is best to take no chances. Now what are you doing here? I heard you had been taken by Hakon."
The boy swiftly outlined his adventures, told of the trap that was to be laid for the Jomsborg fleet, and asked Ulf to help them.
"Of course, Sigurd, of course! I can stow you two and the Lady Astrid away comfortably, but if we are overhauled—well, my men are no fighters, you know!"
"We'll take our chance of that," replied Sigurd, thanking him warmly for his aid. "Now, when can you sail? Every minute counts."
"I know, but I can't possibly start sooner than the morning of the third day from now. Say midnight of the second night after this. My cargo is not all in, and it would look too suspicious altogether. But the 'Otter' is a fast ship, and we will get down the coast much faster than will Eirik with his warships."
"You can expect us then," said Sigurd. "Will you meet us on shore?"
"It will be better so," replied Ulf. "I will get the 'Otter' farther out before nightfall, and will wait for you opposite here with a small boat."
With a parting handshake Sigurd slipped over the side again, and rowed slowly through the shipping on his way back. As he passed a large ship, he saw that the sailors were making a clumsy effort to raise the sail. Indeed, from their looks he took them for newly raised levies from the country on their way to join Hakon, as the ship was a war vessel. He rested a moment, watching them with a smile; then it died away as he saw an officer, whose back was turned toward him, standing directly beneath the heavy spar that the men were hoisting.
"He'd better look out," thought Sigurd, "if those fellows lost their grip on the rope—ah, I thought so!"
For, even as the thought flashed through his mind, the rope had slipped loose from the men, and the yard fell, striking the officer a glancing blow and knocking him overboard.
With a shout Sigurd drove his oars into the water and reached the place where the man had gone down before the confused men on the ship could put out a boat. He could see nothing of the man, so, quickly throwing off his fur cap and cloak and unbuckling his sword-belt, Sigurd took a long breath and dived from the boat's side.
For an instant the ice-cold water paralyzed him; then, opening his eyes, the boy struck down. There, just beneath him, was the senseless face of—Thorkel Leira!
Sigurd checked his stroke. Why not leave this traitor and villain to his fate, so richly deserved? Why risk his own life for that of a worthless fellow such as Thorkel? But he only hesitated an instant; hastily gripping the man's hair, he made for the surface.
Although Sigurd was a good swimmer, he reached the air with a great sigh of relief, for he had been under water nearly a minute, and the water was too cold for comfort. Thorkel had been struck senseless and made no resistance.
As he emerged, a shout sounded in his ear, and there beside him was a small boat. His own skiff was not far, and after the men at his side hauled up Thorkel, he struck out for his own boat. Sigurd realized only too well that he did not want to be questioned, for any mishap now would ruin their plans of escape; so, paying no heed to the shouts of the Norsemen, he clambered over the stern of his craft, donned his fur coat hastily, and made for the shore.
He pulled up the boat and made off at once. His dripping clothes had already frozen, and the cloak hid most of them,
