The rain drummed against the glass panes while Arthur stared at the cold body lying on the velvet rug. A single golden key rested inside the dead man's open palm, glinting under the dim light of the lamp. No one had entered the locked room, yet the scent of bitter almonds lingered heavily in the stale air. Detective Miller stepped over the threshold and noted the shattered vase scattered across the polished mahogany of the floor. Who could have committed this crime without leaving a single trace of blood or a footprint in the dust? The clock struck midnight as the wind howled through the halls, shaking the heavy curtains of the grand library. He knelt beside the victim and found a torn piece of parchment tucked deep inside the man's silk pocket. The words were written in red ink, warning that the secret would be buried with the soul of Arthur.
