Samwise Gamgee
Bilbo expands his memoirs into a record of the events of "The Lord of the Rings", including the exploits of his kinsman Frodo Baggins and others. He leaves the material for Frodo to complete and organize. Frodo writes down the bulk of the final work, using Bilbo's diary and "many pages of loose notes". At the close of Tolkien's main narrative, the work is almost complete, and Frodo leaves the task to his gardener Samwise Gamgee.
