That night, David stood for a long time in front of the door to a room he had never opened for years. The old house felt much quieter than usual. Dust covered most of the door's surface, but a small keyhole near the handle reminded David of his sister's final message..."The key is with David." He tightly held the pendant engraved with D-17 and examined it more carefully. After a few seconds, he realized that the back of the pendant could actually be opened. Inside was a tiny piece of metal shaped like a key. David froze. "So this is what you meant, Sis?" he whispered softly. With slightly trembling hands, he inserted the small piece of metal into the keyhole. A quiet click echoed through the room. The door finally opened.
