"My gracious goodness! Is it?"

"It is within a few feet of where we're standing. At this moment we're 'hot,' I know--I feel it!"

"That scrap of paper contains, as Mr. Graham puts it, the key of the riddle. It's a minute description of the precise whereabouts of the dead man's hiding place. All we have to do is to find out what it means, and if we are not all idiots, that shouldn't be hard. Why, you've only got to see the house; you've only to look about you, and use your eyes, to at once perceive that it's honeycombed with possible hiding places--just the sort of crevices and crannies which would commend themselves to such a man as this Tom Ossington. Look at this very room, for instance; it's wainscotted. That means, probably, that between the outer wall and the wainscot there's an open space--and who knows what beside? Listen!" She struck the wainscot in question with her open palm. "You can hear it has a hollow backing. Why"--she touched it again more gently, then stopped, as if puzzled--"why, the wood-work moves." She gave a little cry, "Ella."

"Madge?"

They came crowding round her, with eager faces.

"Push it! Push it higher!"
