Return of Fog Lock

Family motto No. 1: Doors and windows must be locked before dark. Family motto No. 2: If you hear a knock on the door in the middle of the night, don't open it or answer it. Family motto No. 3: If a family member returns from a night out, they must recite the family secret message outside the door. If you recite a wrong word, you are not the person you are. I lived by these rules for sixteen years, until my father went out to "get something" one foggy night and never came back. Seven days later, a man who looked exactly like his father stood outside the door and recited the entire secret message fluently. Mother opened the door tremblingly.
