The words were still on his lips when he heard the creaking of a bowstring. An arrow flashed before him, struck against the peak of his helmet and fell at his feet upon the deck. Then he saw the cloaked figure of a man steal quickly away into the shadow of the sails.

Olaf picked up the arrow and examined it. By a mark upon its shaft and the trimming of its feathers he knew it to be an arrow taken from his own cabin. He also knew that its point was poisoned.

"Never did I suspect that I had a traitor in my following," he said as he went aft towards his cabin. "Some man has attempted to take my life. But whosoever he be, I shall surely find him and punish him!"

He searched among the shadows of the bulwarks and down among the rowers' benches, but saw no trace of his secret enemy. When he entered his cabin he found only Thorir Klakka, lying, as it seemed, asleep upon the floor with an empty drinking horn beside him and breathing heavily. Olaf thought that the man had been taking over much mead, so left him there and went out upon the deck to tell his friend Kolbiorn of this attempt upon his life. But as soon as Olaf was out of the cabin Thorir rose, wakeful enough now that he was alone, and took from under him a longbow which he placed in the rack.

"The man bears a charmed life!" muttered Thorir, "or else he has eyes in the back of his head. Ill luck is mine! Had I but aimed a finger's breadth lower he would now have been dead, and Earl Hakon might have been saved the trouble of laying traps for him!"

Throughout that night Olaf was engaged searching for his unknown enemy; but without avail. He questioned every man on board, but all swore by the sign of the cross that they had seen nothing. For a time Olaf was forced to suspect Thorir Klakka; but he soon dismissed the thought. Thorir's conduct towards him had been from the time of their first meeting so full of goodwill and seeming friendliness that it was impossible to fix suspicion on him, and indeed there was no man among all the ship's company who showed more concern over this matter than did Thorir, or who made greater efforts to discover the miscreant who had dared to attempt the life of the well beloved chief.

CHAPTER XV: THE EVIL EARL.

Early on the next morning the ships were within sight of the high lying coast of Norway. By Thorir's treacherous advice, Olaf had steered his course for a part of the country where Earl Hakon's power was greatest, and where it was expected that Hakon himself might at that time be staying. Steering in among the skerries Olaf made a landing on the island of Moster, in the shire of Hordaland. Here he raised his land tent and planted in front of it the cross, together with his own standard; and when all the men were ashore he had his priests celebrate the mass. He met with no opposition, for the people of the place were then busy on their fields, and there was nothing unusual in the sight of a few peaceful ships anchoring off their shores.

Thorir had advised a landing on this particular island because, as it had been arranged, he knew that here he would gain private news of Earl Hakon, and learn how he might best betray King Olaf into Hakon's clutches. When Thorir heard, therefore, that the earl was at Trondelag, he told Olaf that there was nothing for him to do but to keep it well hidden who he was, and to sail northward with all diligence, so that he might attack Earl Hakon unawares and slay him. At the same time he sent secret word to Hakon, bidding him prepare his plans for the slaying of Olaf Triggvison.

Believing every word that Thorir told him, and trusting in the man's seeming honesty, Olaf accepted the advice, and fared northward day and night until he came to Agdaness, at the mouth of the Thrandheim fiord, and here he made a landing.
