Query: Aqua Alta (Audio Book)

I have listened with appreciation to five of Donna Leon's Commissario Brunetti novels. Now I have come to Aqua Alto and sadly must give an emphatic thumbs down! This negative review is not because of the gay advocacy theme, which IMO is an interesting and credible commentary. The negativity comes from the atrocious Blackstone Audiobooks production which used some untrained 19-yr-old American English speaker for Brunetti and other male voices. The male readings are a disaster and a violation of the author's work. In the context of the gay advocacy theme, the crude lack of artistry of the male voices turns the gay advocacy into mockery and polemic - not the author's intention I assume.
