The theatres were just out and the boulevard was crowded with people intent on making a night of it. Numberless automobiles containing the fashionable and rich of Paris blocked the streets. The restaurants were brilliantly illuminated, and as carriages discharged their occupants before the doors, one glimpsed the neat feet and ankles of daintily clad women as they crossed the sidewalk and disappeared inside, following their silk-hatted escorts, conscious of their own importance. Many years of active service in Paris as chief reporter of _La Capitale_ had brought Jerome Fandor in touch with a good third of those who constitute Parisian society, and rarely did he fail to exchange a nod, a smile, or half a dozen words of friendly greeting whenever he set foot out of doors. But in spite of his popularity he led a lonely life--many acquaintances, but few close friends. The great exception was Juve, the celebrated detective. In fact, Fandor's complex and adventurous life was very much bound up with that of the police officer, for they had worked together in solving the mystery of many tragic crimes. On this particular evening, the reporter became gradually imbued with the general spirit of gaiety and abandon which surrounded him. "Hang it," he muttered, "I might go and hunt up Juve and drag him off to supper, but I'm afraid I should get a cool reception if I did. He is probably sleeping the sleep of the just and would strongly object to being disturbed. Anyway, sooner or later, I'll probably run into some one I know." On reaching Drouet Square, he espied an inviting-looking restaurant, brilliantly lit. He was about to make his way to a table when the head waiter stopped him. "Your name, please!" "What's that?" replied Fandor. The waiter answered with ironical politeness: "I take it for granted you have engaged a table. We haven't a single vacant place left." Fandor had the same luck at several other restaurants and then began to suffer the pangs of hunger, having, on principle, scarcely touched the heavy dishes served at the banquet. After wandering aimlessly about, he walked toward the Madeleine and turned off into the Rue Royale in the direction of the Faubourg Saint-Honore. As he was passing a discreet looking restaurant with many thick velvet curtains and an imposing array of private automobiles before it, he heard his name called. He stopped short and turned to see a vision of feminine loveliness standing before him. "Isabelle de Guerray!" he cried. "And how are you, my dear boy? Come along in with me." Fandor had known Isabelle de Guerray when she was a young school teacher just graduated from Sevres. Her career, beginning with a somewhat strange and unorthodox affair with a young man of good family who had killed himself for her, had progressed by rapid strides and her name was frequently cited in the minor newspapers as giving elegant "society" suppers, the guests being usually designated by their initials!
