Snow had buried the village road before anyone found Eleanor. She lay beneath the grandfather clock, one hand still outstretched. The clock had stopped at midnight, though dawn was breaking. Inspector Vale entered quietly, carrying melting snow on his shoulders. Behind him, the housekeeper twisted a bloodstained handkerchief between fingers. She insisted the doors had remained locked throughout the night. Yet muddy footprints crossed the carpet, ending beside the body. None returned toward the door, or approached from any window. Vale knelt and noticed something glittering beneath Eleanor’s curled fingers. It was a key, still warm against her cold palm. From upstairs came a single knock, followed by a scream. The housekeeper whispered, “That room has been empty for years.”
