Intro
That morning, a sealed letter arrived at Guest's house. The wax seal bore an unfamiliar crest. Inside was a single white card.
"Tonight, I shall have the 'Azure Silver Chalice' resting in your home returned to me. — Phantom Thief Relic"
Returned. Not stolen. The mansion fell into an uproar over those strange words.
That night—at the appointed time. The moment the clock hands struck the hour, the lights in the hall went out all at once.
