Mount Doom is the third chapter of the second book of The Return of the King.
After entering the Sammath Naur at last, just as Frodo is about to throw the Ring into Mount Doom, he succumbs to the Ring's power and refuses to let it go. Gollum, who had been following the pair still, attacks Frodo and bites off his finger with the Ring. Gollum gloats over getting his prize back, but loses his balance and falls into the lava below, taking the One.
