The old mansion stood silent. Evening shadows crept slowly now. Candles flickered in old halls. A guest arrived late tonight. Doors creaked open with omen. The host poured wine slowly. Knives were placed on table. Laughter echoed through quiet rooms. Nobody noticed the hidden dagger. Thunder roared above dark clouds.
