I called Mrs. Alvarez back before she could even finish setting her kettle on the stove. She answered on the first ring like she had been holding the phone in her lap the whole time. “I didn’t want to tell you until I was certain who was driving,” she said, her voice dropping down to a harsh whisper. Then she said the woman’s last name, and the air went right out of the room. It was Martha Vance, whose husband sat three rows ahead of us every Sunday and handled the building fund accounts with a big leather briefcase. Was I wrong to check his pocket? People can argue about that until the cows come home, but when you spend twenty-nine years building a house out of dry straw, you want to know who struck the match before you smell the smoke. I didn’t scream and I didn’t throw his coffee mug against the wall when he came home that evening. I just handed him the motel receipt across the kitchen table while he was unlacing his work boots, and I asked him if Martha liked the smell of spearmint gum. He stopped with his hand on his heel, his face going completely gray in the fluorescent light, and didn’t say a single word for a long, long time.
