There is an interesting contrast in the book between the apparently incompetent or extremely unlucky
Nazgul at the beginning of the book, and the terrifying Lord of the Nazgul at the gates of
Minas Tirith near the end. In the latter scene The L of N seems genuinely powerful, and at least willing to even try to take on
Gandalf.
In my view this parallels other similar mood changes through the book. The 1st chapter begins almost in the same vein as "The
Hobbit", e.g. Gandalf as the firework expert with the sticky out eyebrows. After "Shadow of the Past" and then increasingly the book turns not only darker but more self-consistent. This reflects the timescale over which JRRT actually did the writing.
Many of the apparent inconsistencies in the book can be traced to these early chapters. For example, if
Bilbo used
the ring fairly regularly (which I think we can agree that he did) why didn't
Sauron become aware of him?
Re the scene at
Bree, I always read the book that it WAS the Nazgul who attacked the
Inn. The Lord of the Nazgul at the end of the book who faced the
armies of
Gondor would have had no problem with a lighted Inn and a few bumbling drinkers (he didn't know
Aragorn was there). He wouldn't have allowed Ferny or any other person to get hold of the ring.
