Baden-Baden, 1883. The summer capital of Europe. Every summer, sixty thousand guests descended on this town of ten thousand inhabitants. They came to enjoy the natural beauty of the town and its surroundings, the social scene, the baths and the many cultural delights. It was the place for amusement and intrigue. It was the place where fantasy intersected with reality, reputations were made and lost, where the European aristocracy played their games from horse-racing to the casino, from the opera to the bedroom. It was also the place to which Robert Koch, Jeweller, came to make his fortune - and reputation.
