Sigurd, slew him with his own hand, and was himself slain by one of Sigurd's men. Earl Haakon, who, from his Danish retreat, watched the events in Norway, heard these tidings with satisfaction. The sudden check which his ambition had received had made him ill, and for some time he appeared listless, refusing to eat and drink, or to communicate with anybody. But when his plans of vengeance were matured, he rose from his bed, strode forth with his old vigor, and proceeded to weave a complicated net of intrigues. Harold Bluetooth had at that time a difficulty with his nephew Gold-Harold, who demanded a share in the government; and, having confidence in the sagacity of the earl, he asked his advice. The earl saw here his opportunity, and had no scruple in availing himself of it. He dissuaded the king from killing his nephew, because such a deed would arouse indignation and alienate the great party in Denmark, who desired to see Gold-Harold on the throne. Far better would it be if he employed Gold-Harold to punish Harold Grayfell and his brothers, and in the end reward him with the throne of Norway. Thereby the king would increase his own power, and convert a dangerous rival into a friend and ally. This advice seemed good to Harold Bluetooth, and after some persuasion he found courage to act upon it. He sent a friendly message to his foster-son, Harold Grayfell, inviting him to come and take possession of his old fief in Denmark, the income of which he might, indeed, need during the hard times that prevailed in Norway. Harold Grayfell, after some vacillation, accepted this invitation, and sailed to Denmark with three ships and two hundred and forty men; but no sooner had he set foot upon Danish soil than he was attacked by Gold-Harold, who slew him and nearly all his men.
