“By no means will I free you,” he said, “for I know that what I have accused you of is true, and it will cost you an effort to free yourself of the charge.”

She said she was quite ready to do that, and therewith they parted.

After this Thorsteinn remained entirely with the Varangians.  Men say that he acted by the advice of Harald the son of Sigurd, and it is thought that they would not have got out of it as they did if they had not made use of him and his wits.

After a time Sigurd gave out that he was about to go abroad on some business.  His wife did not try to dissuade him.  When he was gone Thorsteinn came to Spes and they were always together.  Her house was built on the very edge of the sea and there were some of the rooms under which the sea flowed.

Here it was that Spes and Thorsteinn always sat.  There was a small trap-door in the floor, known to no one but these two, and it was kept open in case of its being wanted in a hurry.

Sigurd, it must be told, did not go away, but concealed himself so as to be able to watch his wife’s doings.  One evening when they were sitting unconcernedly in the room over the sea and enjoying themselves, in came her husband with a party of men, taking them by surprise.  He had taken some of the men to the window of the room that they might see whether it was not as he had said.  They all said that he had spoken truly, and that it must have been so too on the former occasions.  Then they rushed into the room.

On hearing the noise Spes said to Thorsteinn:  “You must go down here whatever it costs.  Give me some sign that you have got away from the house.”

He promised that he would, and descended through the floor.  The lady closed the trap-door with her foot, and it fell back into its place so that no one could see any mark of the floor having been touched.  Sigurd entered the room with his men, searched, and of course found nothing.  The room was uninhabited and there was no furniture in it, but only the bare floor and a bed, on which the lady was sitting and twirling her fingers.  She paid little attention to them and seemed as if their business did not concern her.  Sigurd thought it altogether ridiculous and asked his followers if they had not seen the man.  They declared that they had seen him most assuredly.

The lady said:  “Now we may say as the proverb has it:  All good things are in threes.  This is your case, Sigurd.  Three times you have disturbed me, if I remember rightly; and now are you any the wiser than you were in the beginning?”

“This time I am not alone to tell the story,” he said.  “For all that you will have to clear yourself, for on no terms will I allow your shameful deeds to go unpunished.”

“It seems,” she said, “that you require the very thing which I would myself propose.  It will please me well to show the falsehood of this accusation, which has been so thoroughly aired that I shall be disgraced if I cannot refute it.”
