Prince Otto of Grossenmark

Prince Otto of Heiligwaldenstein and Grossenmark dies in the twilight woods with his face flung up to the moon, and the court's consternation is compounded by foreign mining experts and Prussian officials more interested in a treasure than in grief. He had always hidden in the inmost chamber, unarmed and alone, which makes his death as much a puzzle of character as of circumstance. His body is the still centre around which the duel, the missing seconds and Father Brown's quiet questions revolve.
