Vance had many amazing gifts and capabilities. He was an art collector in a small way, a fine amateur pianist, and a profound student of aesthetics and psychology. Although an American, he had largely been educated in Europe, and still retained a slight English accent and intonation. He had a liberal independent income, and spent considerable time fulfilling the social obligations which devolved on him as a result of family connections; but he was neither an idler nor a dilettante. His manner was cynical and aloof; and those who met him only casually, set him down as a snob. But knowing Vance, as I did, intimately, I was able to glimpse the real man beneath the surface indications; and I knew that his cynicism and aloofness, far from being a pose, sprang instinctively from a nature which was at once sensitive and solitary.
Vance was not yet thirty-five, and, in a cold, sculptural fashion, was impressively good-looking. His face was slender and mobile; but there was a stern, sardonic expression to his features, which acted as a barrier between him and his fellows. He was not emotionless, but his emotions were, in the main, intellectual. He was often criticised for his asceticism, yet I have seen him exhibit rare bursts of enthusiasm over an aesthetic or psychological problem. However, he gave the impression of remaining remote from all mundane matters; and, in truth, he looked upon life like a dispassionate and impersonal spectator at a play, secretly amused and debonairly cynical at the meaningless futility of it all. Withal, he had a mind avid for knowledge, and few details of the human comedy that came within his sphere of vision escaped him.
It was as a direct result of this intellectual inquisitiveness that he became actively, though unofficially, interested in Markham’s criminal investigations.
I kept a fairly complete record of the cases in which Vance participated as a kind of amicus curiae[8], little thinking that I would ever be privileged to make them public; but Markham, after being defeated, as you remember, on a hopelessly split ticket at the next election, withdrew from politics; and last year Vance went abroad to live, declaring he would never return to America. As a result, I obtained permission from both of them to publish my notes in full. Vance stipulated only that I should not reveal his name; but otherwise no restrictions were placed upon me.
