"There's a P-mobile coming in ahead—"

Dane was irritated by that warning from Rip. He had already sighted that black and silver ground car himself. And he was only too keenly conscious of the nasty threat of the snub nosed weapon mounted on its hood, now pointed straight at the oncoming, too deliberate Traders' crawler. Then he saw what he believed would be their only chance—to play once more the same type of trick as Rip had used to earth them safely.

"Get Hovan under cover," he ordered. "I'm going to crash the tower door!"

Hasty movements answered that as the Medic's limp body was thrust under the cover offered by the upper framework of the crawler. Luckily the machine had been built for heavy duty on rugged worlds where roadways were unknown. Dane was sure he could build up the power and speed necessary to take them into the lower floor of the tower—no matter if its door was now barred against them.

Whether his audacity daunted the P-mobile, or whether they held off from an all out attack because of Hovan, Dane could not guess. But he was glad for a few minutes of grace as he raced the protesting engine of the heavy machine to its last and greatest effort. The treads of the crawler bit on the steps leading up to the impressive entrance of the tower. There was a second or two before traction caught and then the driver's heart snapped back into place as the machine tilted its nose up and headed straight for the portal.

They struck the closed doors with a shock which almost hurled them from their seats. But that engraved bronze expanse had not been cast to withstand a head-on blow from a heavy duty off-world vehicle and the leaves tore apart letting them into the wide hall beyond.

"Take Hovan and make for the riser!" For the second time it was Dane who gave the orders. "I have a blocking job to do here." He expected every second to feel the bit of a police blaster somewhere along his shrinking body—could even a space suit protect him now?

At the far end of the corridor were the attendants and visitors, trapped in the building, who had fled in an attempt to find safety at the crashing entrance of the crawler. These flung themselves flat at the steady advance of the two space-suited Traders who supported the unconscious Medic between them, using the low-powered anti-grav units on their belts to take most of his weight so each had one hand free to hold a sleep rod. And they did not hesitate to use those weapons—spraying the rightful inhabitants of the tower until all lay unmoving.

Having seen that Ali and Rip appeared to have the situation in hand, Dane turned to his own self-appointed job. He jammed the machine on reverse, maneuvering it with an ease learned by practice on the rough terrain of Limbo, until the gate doors were pushed shut again. Then he swung the machine around so that its bulk would afford an effective bar to keep the door locked for some very precious moments to come. Short of using a flamer full power to cut their way in, no one was going to force an entrance now.

He climbed out of the machine, to discover, when he turned, that the trio from the Queen had disappeared—leaving all possible opposition asleep on the floor. Dane clanked on to join them, carrying in plated fingers their most important weapon to awake public opinion—an improvised cage in which was housed one of the pests from the cargo hold—the proof of their plague-free state which they intended Hovan to present, via the telecast, to the whole system.
