"The Fellowship of
the Ring will do, I think; and fits well with the fact that the last chapter of the Volume is The
Breaking of the Fellowship. The Two
Towers gets as near as possible to finding a title to cover the widely divergent
Books 3 and 4; and can be left ambiguous - it might refer to
Isengard and
Barad-dur, or to
Minas Tirith and B; or to Isengard and Cirth Ungol. On reflection I prefer for Vol. III The
War of the Ring, since it gets in the Ring again; and also is more non-committal, and gives less hint about the turn of the story; the chapter
titles have been chosen also to give away as little as possible in advance."
