Beardsley pressed his point. "You'll pardon my saying it, sir, but I do realize what the Carmack Case means—to you personally. So much build-up and publicity, and the people demanding a verdict ... why, if the case were to snag now—"

"Unthinkable!" A shudder touched Mandleco's long, lean frame. "Out with it, man! What are you trying to say?"

Beardsley was suddenly sweating. He felt as if a long tube were inside of him, hot and throbbing, reaching up with a surge of pulse to his temples. It had to be now. He had to say it.

"Well," he gulped. "Just this, sir. I think the case can be cracked right now. Today. Without ECAIAC."

"Nonsense! Without ECAIAC? Why, that's—"

"Sure. You think it's crazy. But I tell you I can do it!" Beardsley's words came fast and urgent. "I've followed this case from the beginning, I processed it, I'm familiar with every angle. I tell you, I can deliver the killer. Give me permission to try!"

Mandleco stared at Beardsley as if he were some queer specimen under a microscope; his mouth opened to speak, then he clamped his teeth tightly and strode away.

He turned back abruptly. "So you think you have the solution. You actually—do—think it!" His eyes narrowed down, no longer amused, as he fixed the little serologist with a peculiar gaze. "Go on, Beardsley. Your suggestion at least has the novelty of imagination!"

"The novelty of experience," Beardsley said bitterly. "With your permission and co-operation I can solve this case, together with positive evidence that will hold up in any court! What's more, I'll do it today. A guarantee," Beardsley said pointedly, "which I dare say you no longer have from ECAIAC."
