Wells had his own affair and this book was apparently partially based off that - I'm not sure if we're supposed to feel sympathetic as the main character and his mistress have a whole Romeo/Juliet "I can't bear to be parted from you and I might kill myself" moment because the guy is cheating on his wife! No sympathy for you sir!
The book really trudged on too. I don't have any interest in politics and we had to read the character's whole life story of how he got into politics. It only got interesting right at the end where the guy decided to abandon his wife and run away with his lover.
