'4 January 1954 Rayner Unwin sends
Tolkien a rough draft of the note about TT and RK that follows the text at the end of FR.'
22 January: '... In response to the draft note sent by Unwin on 4 January, he has had 2nd thoughts about the title 'The Two
Towers'. "It must if there is any real reference to volume II refer to
Orthanc and The
Tower of Cirith Ungol . But since there is so much made of the basic opposition of the
Dark Tower and
Minas Tirith, that seems very misleading. There is, of course, actually no real connecting link between
Books III and IV, when cut off and presented separately as a volume. "
23 February 1954
'... He also returns, rewritten, the note for the last page of FR.'
