"Blooming, thank you, Professor Karkaroff," Dumbledore replied. Karkaroff had a fruity, unctuous voice; when he stepped into the light pouring from the front doors of the castle they saw that he was tall and thin like Dumbledore, but his white hair was short, and his goatee (finishing in a small curl) did not entirely hide his rather weak chin. When he reached Dumbledore, he shook hands with both of his own.
