The key didn’t fit any lock I owned, yet every year on my birthday it appeared in a different place inside my house.
The little voice hit me harder than the burning key in my pocket. I didn’t have any children. I had never been married. Yet the word Dad sounded so natural that, for one impossible moment, I almost answered. The man in the gray coat stepped in front of me before I could move another inch. “Don’t respond,” he warned. “The first conversation is what binds you.” The child knocked gently from the other side of the door. “Dad… it’s getting dark in here.” Every instinct inside me screamed to open it. I looked toward the bookseller, hoping for an explanation. Instead, he walked to one of the shelves and pulled out a faded wooden box. Inside were twenty-six black iron keys identical to mine. Each one carried a different number. One through twenty-six. Every slot was filled except the last. “Yours is the only key still traveling,” he said quietly. “The others already belong somewhere.” I picked up Key Number Twelve. It felt cold, ancient, almost lifeless. “Who do these belong to?” I asked. The bookseller looked at me for several seconds before answering. “Different versions of people who made different choices.” Before I could ask what that meant, the man in the gray coat grabbed my wrist. “We don’t have time.” He led me to a dusty map hanging on the wall. It showed the bookstore, but the building was impossible on the inside. Corridors twisted into circles. Rooms overlapped one another. Several doors were marked only with numbers. Door 27 was the only one outlined in red. Scribbled beneath it were words that looked frighteningly familiar. Never unlock it twice. I recognized the handwriting immediately. It was mine. The gray-coated man took a slow breath. “You deserve to know who I am.” He reached into his wallet and handed me an old driver’s license. The photograph showed him exactly as he stood before me. The name beneath it read Daniel Carter. My name. My birthday. My hometown. Only the birth year was twenty-two years earlier than mine. “You’re…” I whispered. He nodded. “The first Daniel.” My mind refused to process the sentence. “That’s impossible.” “It should be,” he replied. “But Door Twenty-Seven doesn’t connect places. It connects decisions.” The child knocked again, more urgently this time. “Dad… they’re coming.” My older counterpart closed his eyes for a moment, as though he had heard those words too many times already. “I heard that same voice thirty years ago,” he said softly. “I opened the door because I thought I was saving someone.” He rolled up his sleeve farther. The scar on his arm continued across his shoulder and disappeared beneath his shirt. “Instead, I lost everyone who remembered the life I’d lived.” The bookseller unlocked another cabinet and removed a stack of old Polaroids. Every photograph showed a different Daniel standing beside Door 27. Some looked younger than me. Some looked decades older. One wore a military uniform. Another stood in a hospital gown. One had gray hair and leaned on a cane. But every single photograph ended the same way. The next picture in each sequence showed only the door. The Daniel in the previous frame was gone. “How many are there?” I whispered. “Twenty-six,” the bookseller replied. “You’re the twenty-seventh.” My pulse pounded in my ears. “What happened to the others?” Neither man answered. Instead, the bookseller handed me the final photograph. It had been taken only hours earlier. I was standing in front of Door 27 exactly as I was now, wearing the same clothes, holding the same key. Behind me stood the gray-coated Daniel and the bookseller in the exact same positions. The only difference was the door. In the photograph it was already open. Beyond it stood a little boy no older than eight. He looked up at me with familiar green eyes. My eyes. Around his neck hung a silver compass my own father had given me when I was a child. It had been lost years ago. Written across the bottom of the photograph, in my handwriting, were seven words. He isn’t your son until you open it. Before I could drop the picture, the entire bookstore shook violently. Dust rained from the ceiling. Every key inside the wooden box began rattling at once, as if something on the other side of every numbered door had awakened together. The bookseller’s calm expression disappeared for the first time. He looked directly at me and said, “It’s never happened before.” “What?” I asked. His eyes shifted toward Door 27. The black iron handle was slowly turning by itself. “Someone opened it… from the other side.”
