"You are not outside these walls," he said. "You are not likely to be outside these walls for some time to come. You have described us in language that you have spared no trouble to render abusive. You know too much. And we have our own way here of dealing with enemies of ours who know too much."

There was no mistaking the dreadful threat that

underlay the hoarse speech. There was underground murder in the eyes of Sartoris. Berrington smiled scornfully.

"I know exactly what you mean," he said; "indeed, I know more than you give me credit for. And I will make my suspicions certainties."

Berrington advanced swiftly to the table and laid a hand on the sheet that covered the still, silent form there. Another instant, and the whole mystery would have been exposed. But Sartoris propelled his chair forward and grabbed Berrington by the arm.

"You cowards," he yelled. "If I were not cursed by these crippled bones of mine, I would have plucked that fellow's heart from his body. Don't stand there like a lot of mummies. Pull him back, I say, pull him back."

The harsh, ringing command seemed to restore the other listeners to a sense of what they owed to themselves. With a cry, the man called Reggie was on Berrington, though Mary Sartoris had fallen and clasped him around the knees. With an oath, Bentwood darted forward and flung himself upon Berrington's shoulders. The struggle was a hot one, for the Colonel fought well, but the odds were too many for him, and he was borne at length heavily to the ground. His head came in contact with the floor, and he lay there just a minute dazed and giddy.

He had failed, too, which was the most humiliating part of the business. He had, at any cost, resolved to make assurance doubly sure. He could see the grinning triumph on the face of Sartoris, as he scrambled to his feet; he could see the tears in Mary's eyes. For the personal danger to himself he cared nothing.

"Let's make an end of it," Sartoris cried. "He's too dangerous to live. Let us make an end of him. Dead men tell no tales."

"No, no," Mary cried. "You shall not do it. No, no."
