"It's quite evident," I suggested, "that they know that we are interested in them now."

"Yes," he agreed. "There wasn't any use of watching them further from under cover. I wanted them to see me, just to find out what they would do."

Kennedy was right. Indeed, even before we turned again, we found that the Senora and Alfonso had risen and were making their way slowly to the elevators, still talking earnestly. The lifts were around an angle, and before we could place ourselves so that we could observe them again they were gone.

"I wish there was some way of adding Alfonso's shoe-prints to my collection," observed Craig. "The marks that I found in the dust of the sarcophagus in the Museum were those of a man's shoes. However, I suppose I must wait to get them."

He walked over to the desk and made inquiries about the de Moches and Whitney. Each had a suite on the eighth floor, though on opposite sides and at opposite ends of the hall.

"There's no use wasting time trying to conceal our identity now," remarked Kennedy finally, drawing a card from his case. "Besides, we came here to see them, anyhow." He handed the card to the clerk. "Senora de Moche, please," he said.

The clerk took the card and telephoned up to the de Moche suite. I must say that it was somewhat to my surprise that the Senora telephoned down to say that she would receive us in her own sitting room.

"That's very kind," commented Craig, as I followed him into the elevator. "It saves planning some roundabout way of meeting her and comes directly to the point."

The elevator whisked us up directly to the eighth floor and we stepped out into the heavily carpeted hallway, passing down to Room 810, which was the number of her suite. Further on, in 825, was Whitney's.

Alfonso was not there. Evidently he had not ridden up with his mother, after all, but had gone out through another entrance on the ground floor. The Senora was alone.
