The rain lashed against the window of the old library as the clock chimed midnight, a harsh sound. On the floor lay the curator, a silver chess piece clutched in his stiffened hand, his eyes open. Detective Aris strode in, his coat still dripping, his jaw clenched as he surveyed the silent, crowded room. Mrs. Chen, the night cleaner, pointed a trembling finger at the gloves on the table, stained with dark blood. Her whispered words implicated Miles, the rival archivist, but something in the scene suggested a cleverly constructed frame.
