I didn’t pack a suitcase. I packed an arsenal. I took emergency leave and printed the deed, the mortgage statements, and the closing documents into a canvas backpack.

Paper weighs almost nothing, and it can hold up a house.

So there I stood on the welcome mat at Maplewood Court, jet lag burning out of my blood, while Melissa — in a silk robe with a coffee mug — mistook me for a cleaning girl she’d hired online and walked away from the open door, leaving me to step into my own property like a ghost.

I followed the sound of a bristle brush on wet stone out through the French doors. On a cheap foam pad, hands in a bucket of soapy water, knelt the woman who gave me life.
