Query: Disappointed

I loved the first two Bruno books - the lovely countryside, the descriptions of each meal and the wine. The mysteries were interesting the the pace of the book a leisurely stroll. This is 3 different books sandwiched together and maybe I could have cared about the cave people if I had been able to keep interest long enough to finish the first cave chapter, but why slog through a boring read in the hopes that at some point I will care about the characters. I looked forward to the next chapter in the hope that it was short and I could return to the characters in the present day who I liked. But wait, now I have to read another long chapter from WWII. Never mind, I gave up. This was supposed to be a pleasant read but I'm giving up and going to another book.
