Characterization
He was a big, broad handsome man, his Greek heritage as evident in his features as the Irish: heavy-lidded and laden eyes, a thug of a nose, a generous mouth beneath a fat mustache. In a suit, he looked like somebody’s bodyguard; in drag at Mardi Gras, like a fundamentalist’s nightmare; in leather, sublime.
(from Clive Barker, Sacrament, p 257 in paperback edition)
