" His eyes were curiously deep, and a warm, gray color. His mouth was thin-lipped, but a little wide and altogether friendly. His light, straight brown hair was already receding at the temples. He wore it clipped short, and he would be nearly bald before his thirties were out, but since he was not the sort of man to whom good looks are necessary, this would make little difference. "

― Gordon R. Dickson , Necromancer (Childe Cycle, #2)
