I don’t want the perfect marriage. I want revenge… If you had met me a year ago, you wouldn’t have noticed me. A beautiful woman, but a struggling nobody in a tiny apartment, invisible… Meeting Paul changed that.

Other women look at me in envy. They see a couple completely in love.

My husband is dead. I attended his funeral. I watched his casket be lowered six feet into the ground. (Actually, it may have been only five feet, but that still seems like more than enough.)

And so are all his many, many deep, dark secrets which I never really ever bothered to ask him about. He is never coming back.

‘My name is Darcy, I’m your nurse and I’m here to help you.’ I repeat the words I’ve said so many times.

A good nurse. But looks can be deceiving. You shouldn’t trust me–because I don’t even know if I can trust myself.

When you return from a work trip to find your husband dead in the pond, it’s best not to call him a liar and a cheat in front of the cops.
