A gripping psychological thriller, perfect for fans of Lisa Jewell, Alice Feeney, and Donna Tartt.

A good deed. A new friend. A deadly obsession.

I watch Mia and Eddie plan their wedding in their gorgeous house. They’re rich, young, and beautiful. The perfect couple.

But they have a problem. A year ago, Mia’s mother was brutally murdered, and she still doesn’t know the truth about what happened that day.

I’m just the cleaner next door, but I make a plan to help Mia.

Because I know the truth.

In fact, I know everything about Mia and Eddie. I know their foolish dreams, their finances, their dirty little secrets.

And they have no idea what I want.

If they knew, they’d run a mile.
