They saw the change in him. Instead of the genial, drawling, slow-moving old fellow who had seemed thankful for anything he might chance to hear, they were confronted now by an aroused, quick-thinking man whose words came from him with a sharp, clipped-off effect, and whose questions scouted the whole field of their possible and probable information. He stood leaning his elbows on the other end of the piano, facing Webster across the polished length of its broad top. His dominance of the night before, in the library, had returned.
"Now, Mr. Webster," he began, innocent of threat, "as things stack up at present, only two people had the semblance of a motive for killing Mildred Brace—either Eugene Russell killed her out of jealousy of you; or you killed her to silence her demands. Do you see that?"
He had put back his head a little and was peering at Webster under his spectacle-rims, down the line of his nose. He saw how the other fought down the impulse to deny, hesitating before answering, with a laugh on a high note, like derision:
"I suppose that's what a lot of people will say."
"Precisely. Now, I've just had a talk with this Russell—caught him after the inquest. I believe there's something rotten about that alibi of his; but I couldn't shake him; and the Otis testimony's sound. So we'll have to quit counting on Russell's proving his own guilt. We've got that little job on our hands, and the best way to handle it is to prove your innocence. See that?"
The bow with which Webster acknowledged this statement was a curious mingling of grace and mockery. The detective ignored it.
"And," he continued, "there's only one way for you to come whole out of this muddle—frankness. I'm working for you; you know that. Tell me everything you know, and we've got a chance to win. The innocent man who tries to twist black into white is an innocent fool." He looked swiftly to Wilton, who was leaning far back in his chair, head lolling slowly from side to side, the picture of indifference. "Isn't that so, judge?"
"Quite," Wilton agreed, pausing to remove his cigar from his mouth.
"Of course, it's so," Webster said curtly. "I've just told you so. That's why I've decided—the judge and I have talked it over—to give you something in confidence."
"One moment!" Hastings warned him. "Maybe, I won't take it in confidence—if it's something incriminating you."
