[Source] Chappelle (Pronunciation: Shapel) was the éminence grise of Hierarch Cyrus Engelkind Hemmelfart and the head of Novigrad's secret service. He was well known and respected (more accurately, feared) in the city as he maintained law and order through any means necessary. He was generally suspected of using torture, extortion, and blackmail, often helping himself to confiscated possessions. It is not widely known that the "real" Chappelle eventually succumbed to a heart attack and was replaced by a doppler, a much more compassionate person in every way.
