Same size. Same crooked grin. Same three square teeth. It is not their lantern. What follows is one hour of that morning in two places at once — the front steps, where Mr. Pell is sweeping and stops because the lantern is wrong and he cannot say how, and the loading dock, where Mrs. Duarte is signing for a delivery.
