Sooner than they expected they came very near to having their heart's desire fulfilled. And if it had happened as they wished, and if Asgard had lost its goodliest hero, its strongest defense, that would have been red Loki's fault, all Loki's evil planning; for you are now to hear of the wickedest thing that up to this time Loki had ever done. As you know, it was Loki who was Thor's bitterest enemy; and for many months he had been awaiting the chance to repay the Thunder Lord for the dole which Thor had brought upon him at the time of the dwarf's gifts to Asgard. This is how it came about: Loki had long remembered the fun of skimming as a great bird in Freia's falcon feathers. He had longed to borrow the wings once again and to fly away over the round world to see what he could see; for he thought that so he could learn many secrets which he was not meant to know, and plan wonderful mischief without being found out. But Freia would not again loan her feather dress to Loki. She owed him a grudge for naming her as Thrym's bride; and besides, she remembered his treatment of Idun, and she did not trust his oily tongue and fine promises. So Loki saw no way but to borrow the feathers without leave; and this he did one day when Freia was gone to ride in her chariot drawn by white cats. Loki put on the feather dress, as he had done twice before,--once when he went to Jotunheim to bring back stolen Idun and her magic apples, once when he went to find out about Thor's hammer. Away he flew from Asgard as birdlike as you please, chuckling to himself with wicked thoughts. It did not make any particular difference to him where he went. It was such fun to flap and fly, skim and wheel, looking and feeling for all the world like a big brown falcon. He swooped low, thinking, "I wonder what Freia would say to see me now! Whee-e-e! How angry she would be!" Just then he spied the high wall of a palace on the mountains. "Oho!" said Loki. "I never saw that place before. It may be a giant's dwelling. I think this must be Jotunheim, from the bigness of things. I must just peep to see." Loki was the most inquisitive of creatures, as wily minded folk are apt to be. Loki the falcon alighted and hopped to the wall, then giving a flap of his wings he flew up and up to the window ledge, where he perched and peered into the hall. And there within he saw the giant Geirröd with his daughters eating their dinner. They looked so ugly and so greedy, as they sat there gobbling their food in giant mouthfuls, that Loki on the window-sill could not help snickering to himself. Now at that sound Geirröd looked up and saw the big brown bird peeping in at the window. "Heigha!" cried the giant to one of his servants. "Go you and fetch me the big brown bird up yonder in the window."
