Query: Great Book

I really enjoyed this book and would have given it a 5 rating, but it was about 100 pages too long. The book gives great insight not only to WW II but it also gives insight into Berlin during the time of the Berlin Wall. There were a few characters that were not necessary to the story and plot line, but Mr. Iles kept my attention throughout the overlong book. It was my 1st novel by Mr. Iles but I will definately try another.
