Rain tapped the manor windows as a sudden scream split the dark ballroom, waking every frightened guest all at once. Under the chandelier light, Lord Ashcombe lay with a crushed rose stem beside his bloody lips, smiling ever so faintly. Detective Mara stepped through the trembling bodyguard line, her wet trench coat dripping dark secrets onto the polished marble floor. Every suspect hid a motive, but none could explain the blood on the torn letter found near the dead lord. Mara knelt beside the body and noticed a single white feather resting on the cold open hand of the lord.
