The black ship hovered above the parked ship, and then dropped sharply, ramming the observation dome on top with its harder, smaller bottom. The two ships tilted and fell, crushing the ground near the poised driver tube. Space-suited men assaulted the damaged ship, broke into the bent and battered plates and emerged with three men who were still struggling to get their suits adjusted properly. Channing's men took over the poised driver tube, and in their own ship, Walt spoke over a sub-ether radio of a different type. "Don, we got him." Don answered from Venus Equilateral, and his voice had no more delay than if he had been within a hundred yards of the crater on Luna. "Good. Stay there; you can contact the Lunar Relay Station from there. Wes is all ready on Station 3 above Northern Landing with his set, and Jim Baler is at the Deimos Station." "Hi, Walt," came Wes' voice. "Hi," said Jim Baler. "Hello, fellows," said Walt. "Well, what cooks?" "Kingman," said Channing. "You've got your orders, Walt. When Kingman expects the market to go down, tell him it's still going up. We'll figure this out as we go along, but he won't like it at all." There was silence for a few minutes, and then Don said: "Walt, Kingman's sent a message through the Northern Landing station now. He says: 'Dump a block to shake the suckers loose. This is pyramided so high that they should all climb on the sell-wagon; running the market down of their own weight. When it hits a new low, we'll buy, and this time end up by having control.' When he starts to run the market down, you buy at Terra." Minutes later, the message hit the Terra market, and Kingman's agent started to unload. The stock started off at six hundred and nine, and it soon dropped to five-forty. It hovered there, and then took another gradual slide to four-seventy. Then a message came through the regular beam station which Walt intercepted, decoded with Terran Electric's own code book, and read as follows: "I. C. Preferred coming in fast. Shall we wait?" Walt chuckled and spoke into the driver modulator. "Kingman," he said, "some wiseacre is still buying. I. C. Preferred is running at seven-ninety! What now?" In the Venus Equilateral radio, he said: "Don, I just fixed him." From Venus, Wes said: "You sure did. He's just giving orders to drop some more stock. This is too dirty to be funny, but Kingman asked for it. I know him. He's got this set up so that no one can do a thing on this market program without orders from him. Too bad we can't withhold the Northern Landing quotations from him." The Lunar Beam brought forth another message intended for Kingman's interceptor at Luna. "I. C. Preferred is dropping like a plummet. When can we buy?" Walt smiled and said into Kingman's set-up: "Kingman! I. C. Preferred is now at eight hundred and seventy!" Not many minutes later, Wes said: "That was foul, Walt. He's just given orders to run the market down at any cost."
