"I've got to! I've got to act!"

His confusion was manifest. He did not know what to do, and he was silent, hoping for a suggestion from her. She let him wait. The pause added to his embarrassment.

"What would—that is," he forced himself to the appeal, "I was wondering—anything occur to you? See any way out of it?"

"Of course, I know nothing about such procedure," she replied to that, slowly, as if she groped for a new idea. "But, if you got the proof from somewhere else, enough to warrant the arrest of Webster——" Her smile deprecated her probable ineptness. "If Arthur Sloane——"

He fairly fell upon the idea.

"Right!" he said, clapping his hands together. "Sloane's no dying man, is he? And he knows the whole story. Right you are, Mrs. Brace! He can shake and tremble and whine all he pleases, but tonight he's my meat—my meat, right! Talk? You bet he'll talk!"

She considered, looking at the opposite wall. He was convinced that she examined the project, viewing it from the standpoint of his interest, seeking possible dangers of failure. Nevertheless, he hurried her decision.

"It's the thing to do, isn't it?"

"I should think so," she said at last. "You, with your mental forcefulness, your ability as a questioner—why, I don't see how you can fail to get at what he knows. Beside, you have the element of surprise on your side. That will go far toward sweeping him off his feet."

He was again conscious of his debt of gratitude to this woman, and tried to voice it.
