  • "Most of the young Masters already have their own personal nut free and clear. “Nut�? is the term for the amount of money you need salted away in weather-proof investments in order to generate enough interest to live comfortably in Greenwich on Round Hill Road, Pecksland Road or Field Point Road in a house built before the First World War in an enchanting European style, preferably made of stone featuring the odd turret, with a minimum of five acres around it and big enough to be called a manor. Every Master of the Universe knows the number."
