It was a most Unexpected Party. Bilbo had no idea that he was going to be throwing it, for one thing.
But despite all the misunderstandings that Gandalf had apparently deliberately fostered (who says you can’t have a few laughs while you’re saving the world?), in the end, one bemused middle-aged hobbit with no prior experience at anything more challenging than walking down to the pub had agreed to travel halfway round the world with thirteen dwarves he didn’t know to steal things from a dragon. Because why not?
More than a year after he had departed, and after numerous adventures, after triumphs and losses, Bilbo Baggins returned to his home of Bag End, in the Shire. His long adventures there and back again are completed; he carries with him the One Ring (albeit not yet recognised as such), and believes that all his troubles lie behind him.
He is mildly discombobulated to discover that he has been declared dead and that certain of his relatives are attempting to claim his possessions. The matter is soon sorted out, although Bilbo’s penchant for adventures, the strange company he keeps (elves, dwarves and even wizards come to visit at times), and, we must suppose, a certain jealousy of his wealth, do little to endear him to most other hobbits.
