This was an interesting one. I fully expected a "husband wants his wife's money, kills his wife for it and also has an affair" but it was a bit different.
Tabitha and Conner were teenage lovers. They lost touch but she always knew where Conner was. He married Nina and war all over the news with her. Tabitha and Conner meet once again and start an affair of their own. Then Nina dies. Even though it's ruled as a suicide, some suspect foul play.

This was a very readable thriller and not all so predictable as I thought it might be. I never really suspected Connor but there were a few doubts. I really liked Tabby. She does good at the end but I don't want to spill much for that that haven't read yet.
