Two detectives met them at the rear door. How many others there were scattered through the house itself, Haynerd could only guess. But he passed inspection and was admitted with the girl. A butler took immediate charge of them, and led them quickly through a short passage and to an elevator, by which they mounted to another floor, where, opening a paneled oak door, the dignified functionary preceded them into a small reception hall, with lavatories at either end. Here he bade them remove their wraps and await his return.

“Well,” commented Haynerd, with a light, nervous laugh, “we’ve crossed the Rubicon! Now don’t miss a thing!”

A moment later the butler returned with a sharp-eyed young woman, Mrs. Ames’s social secretary.

“You will be very careful in your report,” the latter began at once in a business-like manner. “And you will submit the 43 same to me for approval before it is published in your magazine. Mr. Ames deems that imperative, since your recent publication of an essay on modern society in this city. I have a list here of the guests, their business and social standing, and other data. You will run that in full. You will say that this is the most brilliant assemblage ever gathered under one roof in New York. The wealth represented here to-night will total not less than three billion dollars. The jewels alone displayed will foot up not less than twenty millions. Now, let me see,” again consulting her notes.

Haynerd stole a covert glance at Carmen and winked.

“The chef,” the secretary resumed, “was brought over from Paris by Mrs. Ames on her recent return. His name, Pierre Lotard, descendant of the famous chef of the Emperor Napoleon First. He considers that his menu to-night surpasses anything he ever before achieved.”

“May I ask,” interrupted Haynerd, “the probable cost of the supper?”

“Yes, perhaps you had better mention that item. It will be in the neighborhood of three hundred dollars a plate. House and table decorations, about eight thousand dollars. Here is a copy of the menu. Run it in full. The menu cards were hand-illuminated by Parisian artists, and each bears a sketch illustrative or suggestive of the guest to whom it is given.”

“Cost?” queried Haynerd off-handedly.

“Three thousand, if I correctly recall it,” was the nonchalant reply. “As to the viands, you will mention that they have been gathered from every part of the world. Now come with me, and I will give you a hasty sketch of the house, while the guests are assembling in the grand salon. Then you will remain in the balcony, where you will make what notes you wish on the dress displayed. Refreshments will be served to you later in this waiting room. I need not remind you that you are not expected to mingle with the guests, nor to address any one. Keep to the balcony, and quite out of view.”
