"Vittorio Malvora!" I called,my voice ringing with wrath in the echoing cavern. "Madrigal Raith! I am Harry Dresden, Warden of the White Council of Wizards. Under the Unseelie Accords, I accuse you of murder in a time of peace, and challenge you, here and now, before these witnesses, to trial by combat." I slammed my staff down again in another shock of thunder, and Hellfire flooded in the runes of the staff. "To the death."

Utter silence fell on the Deeps.

Damn, there ain't nothing like a good entrance.
