The laminate top of my kitchen island has a tiny pale notch near the corner where my late husband, Arthur, dropped a soldering iron back in the autumn we finished the sunroom, and I found myself staring right at that little scar while Alyssa told me how the bedrooms upstairs were going to be divided. It was a Tuesday morning at 10:14, and the house smelled faintly of lemon oil because I had just finished wiping down the baseboards. I remember the exact time because I had been looking at the wall clock while waiting for the kettle to reach a boil, wondering if I had enough ginger in the pantry to make a fresh pot. I never got around to checking. Alyssa had driven up the gravel driveway in her black SUV, let herself in through the side door without knocking, and dropped her leather tote bag right onto the quartz counter with a sharp slap that made the sugar bowl jump. She didn’t take off her sunglasses until she had already pulled out one of my barstools and seated herself without an invitation.
