"Well, I feel queer about it," objected Dolores Heron. "The creature may be a hotel thief?"
"Nonsense!" fumed the man. "The girl was a child—sixteen or seventeen. We can't mix ourselves up in such an affair. Let's mind our own business."
"You needn't be so cross. I haven't done anything," Dolores reproached him. They went down together, and sat side by side on a rose-coloured brocade sofa in the immense salon generally known as the "hall." Not one of the ladies present was handsomer than Mrs. Heron, not one had more beautiful jewels or a more perfect dress, and all the men openly admired her—except her own husband.
Upstairs the girl in question was making the most of every moment. The queer little key attached to O'Reilly's watch couldn't belong to the desk, still, there might be a box inside the desk which it would fit. Clo searched everywhere and everything. At last, it seemed that nothing was left to try, when suddenly she recalled a paragraph in a newspaper. She had seen it in a Sunday Supplement. Why, yes, Miss Blackburne, the pearl-stringer, had given her the paper that Sunday long ago at Yonkers, to read on the journey home. The paragraph described the up-to-date feature added to some important hotel. Small safes had been placed in the walls of rooms for the benefit of guests, each key being different in design from every other. Clo could not remember the name of the hotel referred to. Perhaps it was this one. If not, the Dietz wasn't likely to let a rival get ahead of it. The girl stared at the wall. Any one of those panels might conceal a safe! There were lots of panels of different sizes, painted a soft gray and edged with delicate white mouldings. To test each would take hours (unless she had luck and hit on the right one first) for there might be a spring hidden in the flowery pattern of the moulding. But—it was to the left side of the room that O'Reilly had flung his anxious glance. She would begin, and hoped to end, her work on the left side. A few minutes spent in thinking out the situation, however, might save many minutes by and by. About those panels, for instance? Which were the most likely to hide a secret?
A frieze or skirting-board of gray painted wood ran round the room to a height of three feet above the pink-carpeted floor. Above this frieze, distributed at regular intervals, were large plaster panels, two on each side of the room, forming backgrounds for gold-framed, coloured prints; and between these were small, narrow panels, ornamented with conventional flower designs. Beneath and above the latter were panels still smaller, placed horizontally, and outlined with white curlicues and flutings. They were about four inches in height by ten inches in length; and on the left side of the wall there were two.
"Just the right size for nice big jewel boxes," Clo thought. "And the lower one's just the right height to open without stretching up. If I were putting a safe into a wall that's the place I'd choose!"
She passed her finger round the edge of one, the white-fluted edge, rather like the decoration of a fancy cake. Nothing happened. No spring clicked. She tried the other with the same result, then stood disappointed, only to return to the attack with new inspiration.
"I bet it pulls out!" she told herself. And—oh, joy, oh triumph!—it did pull out as she pressed her sharp little nails under the white fluting. The whole thing came away from the wall like the loose side of a box, having been kept in place by thin prongs of metal. Behind this cover was a steel or iron door of practically the same dimensions as the panel. It also was painted gray, and showed a tiny keyhole like a slit made with a pair of sharp scissors.
Clo deposited the cover close by on the desk, where it would be within reach if wanted in a hurry. Then she inserted the key attached to O'Reilly's watch. It slipped into place. It turned. It opened the small iron door, and Clo peered into the aperture. In the receptacle lay a pile of greenbacks held together with a paper band. There was also an envelope, but not the envelope the girl had pictured. It was larger, longer, wider, and thicker. It seemed to be made of coarse linen, and instead of the dainty gold seals with the monogram there were five official-looking red ones. Clo's heart contracted. It seemed too bad to be true. But there was plenty of space in this envelope to contain the other, as well as its contents.
"I'll have to open the thing and look," Clo half decided. But if she did, how could she make sure of what she wished to know? If the envelope with the gold seals had been removed, she had no means of recognizing the documents it had contained.
