Jules, the celebrated head waiter of the Grand Babylon, was bending formally towards the alert, middle-aged man who had just entered the smoking-room and dropped into a basket-chair in the corner by the conservatory. It was 7.45 on a particularly sultry June night, and dinner was about to be served at the Grand Babylon. Men of all sizes, ages, and nationalities, but every one alike arrayed in faultless evening dress, were dotted about the large, dim apartment. A faint odour of flowers came from the conservatory, and the tinkle of a fountain. The waiters, commanded by Jules, moved softly across the thick Oriental rugs, balancing their trays with the dexterity of jugglers, and receiving and executing orders with that air of profound importance of which only really first-class waiters have the secret. The atmosphere was an atmosphere of serenity and repose, characteristic of the Grand Babylon. It seemed impossible that anything could occur to mar the peaceful, aristocratic monotony of existence in that perfectly-managed establishment. Yet on that night was to happen the mightiest upheaval that the Grand Babylon had ever known.
