When Thorstein heard these words, he once again began to breathe freely, and throwing back the rug he had drawn over him, stood up before them.

The young men were regular giants, both in size and strength, especially the elder, who had taken his part, and who was quite a head taller than his brother.

Thorstein then went to fetch another plate and cup, and shared in the giants’ meal, after which the two brothers retired to their beds, Thorstein again taking possession of his rugs, where he soon fell soundly asleep, never waking till long after the sun had risen.

Then, while they were at breakfast, the elder giant, whose name was Osric, asked Thorstein whether he would stay on with them; that all he would have to do would be to get their meals ready for them and make their beds. He might also keep his horses in their stables; and as to food and wine, Thorstein would only have to tell them what was needed, and they would always keep the larder and cellar filled, so that Thorstein need never leave the hill.

Thorstein said he would try it for a week. At the end of that time the giants were so well pleased with him, that they urged him to remain with them, for a year, at any rate; and though Thorstein found the life rather dull and stupid, he agreed to stop, Osric, the elder giant, promising him a rich reward at the end of his term. He then handed him the keys of all the rooms in the house, except one key, and this the giant always wore fastened to a string round his neck, only taking it off at night when he went to bed.

When the two brothers had gone off on their daily expeditions, Thorstein made a regular round of the house, looking into the storerooms, cellars, and every room except the one of which Osric kept the key. In vain he tried all the keys on his bunch, hoping one of them might open the lock; but in vain. He then tried to force open the door by throwing himself against it with all his might; but in this also he failed.

Later on, Thorstein noticed that Osric always went into this room every night and morning, while Bifrou, the younger giant, waited for him outside. So one day he asked Osric why, when handing him the keys of all the other rooms, he had kept back this one.

“Surely,” he continued, “if you have found me faithful in all you have entrusted me with, you might also trust me with what is in that room.”

But Osric said there was really nothing particular in the room. Thorstein might be quite sure of that, for, having found him so faithful and honest respecting everything placed under his care, they would certainly also have trusted him if there had been anything valuable in that room.

But although Thorstein pretended that he was quite satisfied with the giant’s answer, he made up his mind to solve the mystery in some way.
