McFadden, Freida. Housemaid series

"I used to clean other people's houses - now, I can't believe this home is actually mine. Though I'm wary of our new neighbor Mrs. Lowell, when she invites us over for dinner it's our chance to make friends. Her maid opens the door, and her cold stare gives me chills. The Lowells' maid isn't the only strange thing. I'm sure I see a shadowy figure watching us. My husband leaves the house late at night. And when I meet a woman who lives across the way, her words chill me to the bone: Be careful of your neighbors. I thought I'd left my darkest secrets behind. But could this quiet suburban street be the most dangerous place of all?"--from back cover
