Olaf the Glorious A Story of the Viking Age by Leighton, Robert, -1934

Then Olaf said, "This is indeed the gladdest news that I have heard for many a long year!" But the words had scarcely fallen from his lips when he realized that he had unwittingly betrayed his long kept secret, for why else should he look upon this as such glad news if he were not himself the lost son of this same Queen Astrid? And it seemed that Thorir had already guessed everything, for he said:

"Glad news must it always be when a son hears that his mother, whom he thought dead, is still alive."

"I did not tell you that Queen Astrid was my mother," Olaf cried in assumed surprise.

"There was no need to tell me," returned Thorir. "For even before I had spoken a word with you I had guessed both your name and kin. You are the son of King Triggvi Olafson. It was you who, in your infancy, were pursued through the land by Queen Gunnhild's spies. It was you who, escaping from Sweden with your mother, were captured by Esthonian vikings and sold into slavery. Then, by some chance which I know not of, you were received at the court of King Valdemar the Sunny. Afterwards you joined the vikings of Jomsburg and passed by the name of Ole the Esthonian. It was you who, in the sea fight against Earl Hakon, rivalled in skill and prowess the most famous vikings of all Scandinavia. A pity it is that instead of going a-warring in England you did not again direct your force against Earl Hakon and drive him from the throne which you, and you alone of all living men, should occupy. It is you, and not Earl Hakon, who are the rightful king of all Norway. The realm is yours by the right of your royal descent from King Harald Fairhair, and I make no doubt that were you to sail into Thrandheim fiord, you would at once be hailed by the people as their deliverer and accepted as their sovereign king."

Thus with guileful speech and subtle flattery did Thorir Klakka seek to entice Olaf over to Norway, to the end that Earl Hakon might secretly waylay him and bring him to his death, and so clear his own path of a rival whom he feared. And Olaf, listening, received it all as the very truth, nor doubted for an instant that the people were waiting ready to welcome him back to the land of his fathers.
