Gollum threw himself backwards, and grabbed as the hobbit flew over him, but too late: his hands snapped on thin air, and Bilbo, falling fair on his sturdy feet, sped off down the new tunnel. He did not turn to see what Gollum was doing. There was a hissing and cursing almost at his heels at first, then it stopped. All at once there came a bloodcurdling shriek, filled with hatred and despair. Gollum was defeated. He dared go no further. He had lost: lost his prey, and lost, too, the only thing he had ever cared for, his precious. The cry brought Bilbo's heart to his mouth, but still he held on.
