The rain fell hard against the library's tall, fogged windows. Detective Mara Voss arrived before the coroner was even called. She knelt beside the body and studied the still face. A single candle had burned down to a black stub. The dead man's hand clutched a torn envelope corner tightly. Voss peeled it free without disturbing the surrounding scattered papers. The library smelled of old leather, wet wool, and secrets. She glanced at the locked door and broken window latch. No one could enter without a key or an axe. Yet the dead man was alive only one hour ago. Voss turned to the butler standing in the doorway's shadow. His hands were too clean for a man finding bodies.
