“Okay sweetheart,” I whisper, giving my little girl Alice a final kiss. “Now remember, after I’ve locked the door, be quiet like a mouse. I’ll come back later, I promise.” Her little face crumples as I turn to leave and my heart breaks. But I have no choice. I have to work, and I have to keep her hidden. It’s just ten days until the new hotel opens. As I push my cleaning cart into the chandeliered honeymoon suite, I wonder how it would feel to stay here as a guest. To watch the sun rise over the ocean, to fall asleep with no fear. I’ll never know, of course.

Long ago, these old friends swore one another to silence, and have never spoken of the deed since.
