Hyrst shook his head. "Latent impressions or not, I don't see how I can help on that. If MacDonald had given the killer any clue—"
A beam of bright blue light no thicker than a pencil struck in through the mouth of the passage. It touched the side of the large stone block. The stone turned molten and ran, and then the beam flicked off, leaving a place that glowed briefly red. Shearing said, "I guess our ten minutes are up."
They were. For a second or two nothing more happened and then Hyrst saw something come sailing in through the crack. His mind told him what it was just barely in time to shut his eyes. There was a flash that dazzled him even through his closed lids, and the flash became a glare that did not lessen. Bellaver's men had tossed in a long-term flare, and almost at once someone followed it, in the hope of catching Hyrst and Shearing blinded and off guard. The eyes of Hyrst's mind, unaffected by light, clearly showed him the suited figure just below him, with its bubble helmet covered by a glare-shield. They directed him with perfect accuracy in the downward sweep of the lead weight he had taken from his boot, and which he still held in his hand. The bubble helmet was very strong, and the gravity very light, but the concussion was enough to drop the man unconscious. Just about thought Hyrst, what happened to me there in the hoist tower, when MacDonald died. Shearing, who had by now adjusted his own glare-shield stooped quickly and took the man's gun.
He said aloud, over the helmet communicator, "The next one that steps through here gets it. Do you hear that, Bellaver?"
Bellaver's voice answered. "Listen, Shearing, I was wrong. I admit it. Let's calm down and start over again. I—"
"Ten minutes ago it was no mercy."
"It's hard for me to behave reasonably about this business. You know what it means to me, what it meant to my father and his father. But I'm willing to do anything, Shearing, if you'll make a deal."
"I'll make a deal. Readily. Eagerly. Give back what your grandfather stole from us, and we'll call it square."
"Oh no we won't," said Hyrst grimly, breaking in. "Not until I find who killed MacDonald."
