While you could technically skip Part III if it bores you stiff, there is nevertheless a hidden gem in there which I would not skip. On pages 274-291, there is a lengthy transcript of an AVRT session under the heading "The Case of Richard," which is definitely worth reading.
I read from cover-to-cover the first time round but on all subsequent reads only properly read Part II—plus the case study you cited above.
One of the negative reviews I read on Amazon was that, while the book was effective, it was padded out too much. At first glance, I might agree but I think in reality Jack Trimpey is just being thorough.
Either way, I recommend reading the whole book at a fairly slow pace at least once before forming an opinion.
