The author excels in creating most vivid pictures of Egypt's customs, natives, music, landscapes, and Egyptian relics/pyramids based on his personal travels to Egypt in his life time. The descriptions of the characters' thoughts and motivations are superb. This novel is about an evil, immoral, greedy, vain woman, the Bella Donna of the title, who is past her prime in looks, and ostracized by London society. In London she meets and marries a young English heir to a Lordship for the sole purpose of gaining riches and societal stature - she does not love him, although he is totally mesmerized and infatuated with her and blind to her character failings. On their honeymoon shipboard voyage to Egypt where he lives and works as an Egyptologist, they meet a wealthy Egyptian businessman with whom she forms an immediate attraction, and whom she pursues later in the story. Her husband fails to inherit the Lordship and related estates - at this point she decides to slowly poison him with lead in his food over several months. Does Bella Donna succeed with her nefarious plans?
