His Deadly Darling by Mink

Luke Knight thinks he can own me, can hurry me into a wedding and then into his bed. He seems to know everything about me. But he’s missed the most important point—I’m dastardly. He thinks he’s my one and only? Not a chance. But I like his estate and all his money, so I’ll bide my time. I don’t obsess over his good looks and the way he makes me feel. Not a bit. Once he’s dead, I’ll be more than happy to be the grieving widow … on a yacht … in the Seychelles … drenched in diamonds.
Cassandra truly believes I’m the bad guy in her world. She’s wrong. I can show her how much she means to me. It will take time and coaxing, but I’ll prove to her our love is deep and true. If she tries to knife me a few times along the way, what of it? After all, a spirited woman is exactly what I need, and Cassandra Carlisle was made for me.
