The clock struck three as the velvet drapes swallowed the last of the fading winter light. A single candle flickered beside the untouched brandy, casting long shadows on the library’s mahogany walls. Emily Hartwell stood frozen in the doorway, her breath fogging the chill air that seeped through the cracked window. The man lay sprawled across the Persian rug, his throat carved open like the gash of a broken violin. No signs of forced entry haunted the silent house, only the whisper of footsteps that vanished mid-room. The murder weapon rested on the mantel—an antique dagger, its hilt dusted, its blade still bearing traces of crimson. Inspector Thorne arrived, his coat heavy with snow, his eyes sharp with the weight of a lifetime of secrets. He crouched near the body, noting the dying man’s last gasp: a plea for someone only the killer would understand.
