This is a quote from a fan letter from W H Auden to J R R Tolkien. Auden went on: "I hoped we would meet him again". Auden wrote the letter from Berlin in 1955 on notepaper headed "Hotel Continental". He had just read a proof copy of LOTR for review. I came across this reading the catalogue of the recent Tolkien exhibition: Tolkien Maker of Middle Earth. Radagast does appear briefly (in an account given by Gandalf, not directly) in FOTR to pass on a message from Saruman to Gandalf for Gandalf to visit Saruman at Isengard. "It's a trap" as Admiral Ackbar would say (funny how that has become his phrase now), though Gandalf judged that Radagast passed on the invitation in all innocence. So why didn't Tolkien make more use of Radagast the Brown in LOTR? What was Radagast doing during the War of the Ring?
