Heavy fog drifted through the silent, cobblestone courtyard, masking the gruesome sight that lay hidden in the dark shadow. Lady Eleanor adjusted her woolen cloak against the biting chill, unaware that she was walking directly toward a cold corpse. Her gloved hand brushed against a damp brick wall before her leather boot struck something shockingly soft and strangely dense. Gasping softly, she leaned down with her flickering brass lantern to illuminate the mysterious object blocking the narrow stone pathway. A silver dagger protruded sharply from a velvet vest, reflecting the faint yellow light onto a frozen, bloodstained face. Recognizing the dead aristocrat instantly, Eleanor smothered a terrified scream and stumbled backward into the thick, suffocating morning mist.
