Calhoun took no part in the agitated conferences among the officials and news reporters at the space-port. But he listened to the talk about him. As the investigating small ship drew nearer and nearer to the deathly-still cargo vessel, the guesses about the meaning of its breakout and following silence grew more and more wild. But, singularly, there was not one suggestion that the mystery might not be the work of blueskins. Blueskins were scapegoats for all the fears and all the uneasiness a perhaps over-civilized world developed.

Presently the investigating space-boat reached the mystery ship and circled it, beaming queries. No answer. It reported the cargo-ship dark. No lights shone anywhere on or in it. There were no induction-surges from even pulsing, idling engines. Delicately, the messenger-craft maneuvered until it touched the silent vessel. It reported that microphones detected no motion whatever inside.

"Let a volunteer go aboard," commanded the chief executive. "Have him report what he finds."

A pause. Then the solemn announcement of an intrepid volunteer's name, from far, far away. Calhoun listened, frowning darkly. This pompous heroism wouldn't be noticed in the Med Service. It would be routine behavior.

Suspenseful, second-by-second reports. The volunteer had rocketed himself across the emptiness between the two again-separated ships. He had opened the airlock from outside. He'd gone in. He'd closed the outer airlock door. He'd opened the inner. He reported.

The relayed report was almost incoherent, what with horror and incredulity and the feeling of doom that came upon the volunteer. The ship was a bulk-cargo ore-carrier, designed to run between Orede and Weald with cargoes of heavy-metal ores and a crew of no more than five men. There was no cargo in her holds now, though. Instead, there were men. They packed the ship. They filled the corridors. They had crawled into every cargo and other space where a man could find room to push himself. There were hundreds of them. It was insanity. And it had been greater insanity still for the ship to have taken off with so preposterous a load of living creatures.

But they weren't living any longer. The air apparatus had been designed for a crew of five. It could purify the air for possibly twenty or more. But there were hundreds of men in hiding as well as in plain view in the cargo-ship from Orede. There were many, many times more than her air apparatus and reserve tanks could possibly have serviced. They couldn't even have been fed during the journey from Orede to Weald!

But they hadn't starved. Air-scarcity killed them before the ship came out of overdrive.

A remarkable thing was that there was no written message in the ship's log which referred to its take-off. There was no memorandum of the taking on of such an impossible number of passengers.

"The blueskins did it," said the chief executive of Weald. He was pale. All about Calhoun men looked sick and shocked and terrified. "It was the blueskins! We'll have to teach them a lesson!" Then he turned to Calhoun. "The volunteer who went on that ship ... He'll have to stay there, won't he? He can't be brought back to Weald without bringing contagion ..."
