An exploration of the history of Kensington Palace, which is currently the official London residence of the Duke and Duchess of Cambridge, the Duke and Duchess of Gloucester, the Duke and Duchess of Kent, and Prince and Princess Michael of Kent. Kate Williams also tells the tale of Elizabeth I's make-up, which was so poisonous that it would be illegal today, with her foundation made of lead and vinegar, her rouge from lead carbonate, and her lipstick from ground alabaster, with side-effects including digestive problems and respiratory issues.
