Calhoun began to see this with a bitter clarity. A curious flicker of light behind him made him turn. The outside-field detector-light was glowing on the control-board. Normally it lighted only to report that the force fields of a landing grid touched the Med Ship when the ship was to be brought to ground, or else when it was to be lifted off to a distance at which a Lawlor drive could be used. There was no reason for it to come on now.
Then the G.C.—general communication—speaker said:
"Calling Med Ship Aesclipus Twenty! Calling Med Ship Aesclipus Twenty! Spaceport control office calling Med Ship Aesclipus Twenty!"
Calhoun threw the answer switch.
"Aesclipus Twenty here," he said shortly. "What's the matter?"
"Checking, sir," said the voice detachedly. "Are you sealed up?"
Calhoun glanced at the air-lock. Aground, of course, it could be opened like the two sets of doors of a vestibule, with direct communication between the inside of the ship and the outside air. However, without thinking particularly about it, Calhoun had left the Med Ship with its own air-renewal system operating.
"Yes," said Calhoun. "I'm sealed up. Why?"
"Message for you, sir," said the voice.
There was immediately the voice of the Health Minister, racked and upset, coming out of the speaker.
"You are requested to leave Lanke at once," it said agitatedly. "Complaint will be made to the Med Service that you attempted to interfere with police measures against crime. Your ship will be lifted off as of now, and you are forbidden to return."
Calhoun said angrily, "The devil you say! I declare a quarantine—"
The communicator clicked. The Health Minister had cut off. The detached control-office voice said woodenly, "I'm lifting you off, sir, as ordered. Lift-off coming . . ."
Calhoun's mouth opened, to swear. Instantly he saw very many more things it had not been the intention of the Health Minister to tell him. He clenched his hands. This wasn't good!
Then the Med Ship stirred, and instantly thereafter seemed to fall toward the sky. Calhoun angrily flipped on the outside vision-plates and his sensations and the statements of the control-office voice agreed. The Med Ship was being lifted off. Below it, the lights of the spaceport receded. Then the street lights of Lanke's capital city were coming into view from behind tall buildings. They winked into sight from farther toward the dark horizon. The small spaceship went up and up.
The smaller, fainter lights of another city appeared. A little while later, the lights of still another. The capital city's pattern of streets grew ever smaller. More other city-glows appeared and seemed at once to dwindle and to drift toward and under the rising Med Ship. There was nothing to be seen anywhere except those minute, diminishing speckles of light.
Presently, the ship went into cloud cover and for seconds the vision screens were blank. Then it reached clear air again and then there was nothing but the starlit cloud cover below, and ten thousand million stars above.
The Med Ship was being lifted by the spaceport's landing grid. Eventually, the stars crept downward, and seemed to draw together, and the world of Lanke became only a diminishing circular patch of darkness against the galaxy's all-surrounding suns. Then the communicator speaker spoke woodenly again.
"Calling Med Ship Aesclipus Twenty! Calling Aesclip . . ."
"Aesclipus here," said Calhoun coldly.
"You are now five diameters out," said the unemotional voice, "And I am about to release you. Check?"
"Check," said Calhoun sardonically.
He flipped off the G.C. transmitter. He felt the new freedom of the Med Ship. He spoke in an even more sardonic tone to Murgatroyd. "This is a first, Murgatroyd! It's the first time a Med Ship man has ever been thrown off a planet because he found out too much!" Then he added with a definite grimness, "It happens that throwing us off the planet verifies what I was only partly guessing and requires what I was hesitating to do."
His tone disturbed Murgatroyd, who of course could not understand what had happened. But he was upset because Calhoun was. Murgatroyd said shrilly, "Chee-chee!"
"We're going back to headquarters," said Calhoun sourly. "We can take our news there quicker than we can send it. Anyhow they'll need more than you and me on Lanke to handle a plague—especially if it's a bad one. But I don't like it!"
He was angry. But it wasn't unprecedented for planetary governments to try to cover up things that would be bad for business. There'd been attempts before now to conceal outbreaks of disease. Some had probably succeeded. Those that failed turned out very badly indeed. Minor epidemics had become major plagues when a prompt call for Med Service help would have kept them minor and wiped them out. The Med Service had big ships, half a mile long and longer, with laboratories and equipment and personnel that could handle emergencies of planetary size. But very, very many lives had been lost because of governments subordinating everything but business to business. They'd tried to prevent business crises and financial panics and industrial collapse. They'd only delayed them—at incalculable costs in lives.
There was another factor, too. If a planetary government once concealed an emergency of this sort, it would never dare admit it later. A certain world in Cygnus had concealed a serious epidemic in order to protect its interstellar trade. Later the fact was learned by Med Service. It made a check of the public health status of that reckless world, in view of its just-learned medical history. It discovered and announced an imminent second epidemic—a perfectly accurate statement of fact. The first epidemic had not been cleaned up properly by the local physicians. The epidemic was cyclic—with a normal period of high incidence after every so many years. So the Med Service quarantined that world—justly—and took stringent measures—wisely—and there was consequently no second plague. But there were many hard-boiled businessmen who fumed that the Med Service had no reason for its action; that it had been punishing the Cygnus world for violating a primary rule for galactic public health. The planet had concealed a disease that might but hadn't been passed on to its customers. Businessmen believed the quarantine a penalty.
So Calhoun knew grimly that if there'd been a hidden plague on Lanke in the past, it would never be admitted now. Never! And any doctor who revealed the historical fact . . . The reason for the silence of Lanke's doctors was abundantly clear.
But this situation wasn't as simple as the Cygnus affair. The dead man Calhoun had partly examined wasn't a native of Lanke. Yet the doctors of Lanke knew all about him and the plague of which he was dying when blaster bolts drove him to a quicker death. He didn't belong on Lanke. Worse, he didn't belong anywhere else. His state of civilization wasn't appropriate anywhere in the galaxy. But he was positively a man. Calhoun had seen drama tapes about lost colonies and villages of castaways, and even elaborate hiding places for refugees from the laws of planets. But he didn't believe them.
