[The Squatter of Amon Rûdh]

I'm not telling anyone the number of letters in the solution, but I will expand on Jenny's interpretation of the clue. As usual, if it seems too simple to be true, it probably is.

A lesser-known cryptic technique, known to such as the benighted souls who do the Grauniad crossword, is for the word that is an anagram to be defined in the clue but not actually given. For example:

'Youngster always allowed to run amok' = Anagram of 'ever let' = Leveret.

I also draw your attention to my use of the phrase 'for example', which is significant, although not at all cryptic in its meaning.
