"Then it is the western wall I want," said Win, turning toward it.
Somewhat mystified, Connie watched him make a minute examination, tapping with the hammer on its entire length.
"I suspect that it's frightfully thick," she said as he stopped, looking disappointed.
"What is on the other side?" he inquired. "Is this whole partition now included in the house?"
Constance led the way to the opposite side of the wall. There lay a large apartment, dimly lighted, but of better workmanship and finish. Win went immediately to the eastern side of this cellar and bestowed upon the partition stones the same minute inspection.
"This wall must really be several feet through," he observed to the watching Constance.
"Probably. But I don't see, Win, what you are trying to get at."
"I hardly know myself, Miss Connie. It's just an idea I had. This would have been the wall nearest the cave. You see I'm not used to having a cave as a sort of household annex, so I can't help thinking it may figure yet in this business."
Connie shook her head. "Perhaps it did once," she said. "Only that cave is more or less common property; many people know of it. We can be sure of one thing; that nothing will be found in it now. How about this floor?"
Win left the wall to inspect by aid of his lantern the huge, roughly-squared blocks forming the cellar floor. Damp, dark and numerous they showed under the light.
