My sister thought my penthouse was hers while I was away. She had no idea what I did for a living. Then everything changed.

The interior cameras activated the moment the door opened. I watched her drop her purse on my entry table, send the children upstairs with the luggage, and walk into my bedroom and set her coat on my bed as casually as a person choosing a seat at a restaurant.
Then she called our mother, and because Paige had never in her life met a speakerphone she did not use, my mother’s voice came through the apartment’s audio system, thin and unmistakable.

“We’re inside,” Paige said.

“Good,” my mother said. “Once you’ve been there a few weeks, Marissa won’t have the heart to put the children out on the street. She talks tough but she always folds. She’s always folded.”
