Every night, a widow would hear trucks coming into the concentration camp. The trucks would arrive empty, but soon enough, they would be filled with prisoners from the camp. When the morning came, the truck would return empty again. No one talked about it, but they knew what happened next. The prisoners were executed; the widow left to worry she might one day be among the dead. Every night, she would corral her six children together, showing them the jewels she’d hidden under the floor planks.
