My name is Seymour Wilbraham Wentworth. I am brother-in-law and secretary to Sir Charles Vandrift, the South African millionaire and famous financier. Many years ago, when Charlie Vandrift was a small lawyer in Cape Town, I had the (qualified) good fortune to marry his sister. Much later, when the Vandrift estate and farm near Kimberley developed by degrees into the Cloetedorp Golcondas, Limited, my brother-in-law offered me the not unremunerative post of secretary; in which capacity I have ever since been his constant and attached companion. He is not a man whom any common sharper can take in, is Charles Vandrift. Middle height, square build, firm mouth, keen eyes - the very picture of a sharp and successful business genius. I have only known one rogue impose upon Sir Charles, and that one rogue, as the Commissary of Police at Nice remarked, would doubtless have imposed upon a syndicate of Vidocq, Robert Houdin, and Cagliostro.
