The author's over use of dialogue was annoying.
Like the author's other books, his protagonists are humanly flawed. A good plot of twin brothers. One almost machine like perfect, the other meets an imperfect end. The surviver becomes successful and unknowingly marries the woman of his dreams, who is the direct cause of his twin's demise. A bitter sweet ending when he finds out the truth.
All characters are flawed. A fair plot with strong, if flawed characters.
This was not the best work by this author. The pace was far too slow. Mostly set in Italy where an American millionaire pursues a mysterious woman. The author writes in a clear style but he could have skipped the class on Italian classical culture.
