"Wait!" he says, imperiously to the men, and then, speaking a stern word of command, he strides away, followed by the conquered and trembling brute.

It is the work of a moment to chain him fast; and then Clifford Heath goes swiftly back to the men, who stand very much as he left them.

"Can this be some trick?" Mr. O'Meara is saying, peering down from the edge of the cellar wall at the mound of earth and the protruding leg.

"There is no trick here," replies Clifford Heath, once more springing down into the cellar. "My dog would not be deceived. Come down here, O'Meara; this thing must be unearthed."

Mr. O'Meara lowers himself carefully down, and the man who has thus far stood sentinel follows suit. Then the four approach the mound once more. For a moment they regard each other silently; then one of the masons says:

"If we had a spade."

"Not yet," breaks in Lawyer O'Meara. "Let's make sure that we have found something before we cause any alarm to be given. Get some small boards; we do not want a spade."

The boards are found easily, and they look to O'Meara again, all but Clifford Heath, who stands near the mound gazing downward as if fascinated. While O'Meara speaks, he stoops swiftly, and then carries his hand to his pocket.

"Let's remove the—upper portion of whatever this is," says the lawyer nervously, "and work carefully. This looks like—"

"It looks like murder," says Clifford Heath, quietly. "Pull away the dirt carefully, men."
