All at once Conway realized how wobbly his legs had become and how hard it was to focus his eyes. And he must have been noticeably slowing down for the nurse to approach him in the first place. He nodded and rolled up his sleeve with fingers which felt like thick, tired sausages.
“Yipe!” he cried in sudden anguish. “What are you using, a six-inch nail?”
“I am sorry,” said the DBLF, “but I have injected two doctors of my own species before coming to you, and as you know our tegument is thicker and more closely grained than yours is. The needle has therefore become blunted.”
Conway’s fatigue dropped away in seconds. Except for a slight tingling in hands and feet and a grayish blotching which only others could see in his face he felt as clear-eyed, alert and physically refreshed as if he had just come out of a shower after ten hours sleep. He took a quick look around before finishing his current examination and saw that here at least the number of patients awaiting attention had shrunk to a mere handful, and the number of Monitors in the room was less than half what it had been at the start. The patients were being taken care of, and the Monitors had become patients.
He had seen it happening all around him. Monitors who had had little or no sleep on the transport coming here, forcing themselves to carry on helping the overworked medics of the hospital with repeated pep-shots and sheer, dogged courage. One by one they had literally dropped in their tracks and been taken hurriedly away, so exhausted that the involuntary muscles of heart and lungs had given up with everything else. They lay in special wards with robot devices massaging their hearts, giving artificial respiration and feeding them through a vein in the leg. Conway had heard that only one of them had died.
Taking advantage of the lull, Conway and Williamson moved to the direct vision panel and looked out. The waiting swarm of ships seemed only slightly smaller, though he knew that these must be new arrivals. He could not imagine where they were going to put these people-even the habitable corridors in the hospital were beginning to overflow now, and there was constant re-arranging of patients of all species to make more room. But that wasn’t his problem, and the weaving pattern of ships was an oddly restful sight…
“Emergency,” said the wall annunciator suddenly. “Single ship, one occupant, species as yet unknown requests immediate treatment. Occupant is in only partial control of its ship, is badly injured and communications are incoherent. Stand by at all admittance locks.. .
Oh, no, Conway thought, not at a time like this! There was a cold sickness in his stomach and he had a horrible premonition of what was going to happen. Williamson’s knuckles shone white as he gripped the edge of the view port. “Look!” he said in a flat, despairing tone, and pointed.
An intruder was approaching the waiting swarm of ships at an insane velocity and on a wildly erratic course. A stubby, black and featureless torpedo shape, it reached and penetrated the weaving mass of ships before Conway had time to take two breaths. In milling confusion the ships scattered, narrowly avoiding collision both with it and each other, and still it hurtled on. There was only one ship in its path now, a Monitor transport which had been given the all-clear to approach and was drifting in toward an admittance lock. The transport was big, ungainly and not built for fast acrobatics-it had neither the time nor the ability to get out of the way. A collision was certain, and the transport was jammed with wounded…
But no. At the last possible instant the hurtling ship swerved. They saw it miss the transport and its stubby torpedo shape foreshorten to a circle which grew in size with heart-stopping rapidity. Now it was headed straight at them! Conway wanted to shut his eyes, but there was a peculiar fascination about watching that great mass of metal rushing at him. Neither Williamson nor himself made any attempt to jump for a spacesuit- what was to happen was only split seconds away.
