“And after some months, the exposure to beauty and wealth took a toll on his mind. He could not pinpoint it at first. Andrei thought human change came from decisions, but actually it came from observation. The brain was a special piano whose song history was never forgotten; one wrong key could destroy the instrument and necessitate years of healing. For Andrei, the multitude of wealthy guests, their walks, accommodation requests, secrets, women, and jewels had achieved his natural lust for luxury ten times over and turned him into a complete ghost.”
