available man into search-parties.
By a fatal combination of circumstances, long-range radio contact had been cut that morning an hour after the departure of the exploration groups—a large spot had appeared on the red sun, producing a heavy bombardment of charged particles in the upper atmosphere. Only the ultra-shortwave transmitters continued to function, and contact was restricted to a radius of about twenty miles. As a crowning stroke of bad luck, a thick fog descended just before sunset and the search had to be called off.
The rescue teams were returning to base when the hovercraft was spotted by a flitter, barely 24 miles from the command-ship. The engine was running and the machine, at first sight undamaged, was hovering above the waves. Carucci alone could be seen, semi-conscious, in the glass-domed cockpit.
The hovercraft was escorted back to base. After treatment, Carucci quickly regained consciousness, but could throw no light on Fechner's disappearance. Just after they had decided to return to base a valve in his oxygen-gear had failed and a small amount of unfiltered gas had penetrated his atmosphere-suit. In an attempt to repair the valve, Fechner had been forced to undo his safety belt and stand up. That was the last thing Carucci could remember.
According to the experts who reconstructed the sequence of events, Fechner must have opened the cabin roof because it impeded his movements—a perfectly legitimate thing to do since the cabins of these vehicles were not air-tight, the glass dome merely providing some protection against infiltration and turbulence. While Fechner was occupied with his colleague, his own oxygen supply had probably been damaged and, no longer realizing what he was doing, he had pulled himself up on to the superstructure, from which he had fallen into the ocean.
Fechner thus became the ocean's first victim. Although the atmosphere- suit was buoyant, they searched for his body without success. It was, of course, possible that it was still floating somewhere on the surface, but the expedition was not equipped for a thorough search of this immense, undulating desert, covered with patches of dense fog.
By dusk, all but one of the search craft had returned to base; only a big supply helicopter piloted by Andre Berton was still missing. Just as they were about to raise the alarm, the aircraft appeared. Berton was obviously suffering from nervous shock; after struggling out of his suit, he ran round in circles like a madman. He had to be overpowered, but went on shouting and sobbing. It was rather surprising behavior to put it mildly, on the part of a man who had been flying for seventeen years and was well used to the hazards of cosmic navigation. The doctors assumed that he too was suffering from the effects of unfiltered gases.
Having more or less recovered his senses, Berton nevertheless refused to leave the base, or even to go near the window overlooking the ocean. Two days later, he asked for permission to dictate a flight-report, stressing the importance of what he was about to reveal. This report was studied by the expeditionary council, who concluded that it was the morbid creation of a mind under the influence of poisonous gases from the atmosphere. As for the supposed revelations, they were evidently regarded as part of Berton's clinical history rather than that of the expedition itself, and they were not described.
So much for the supplement. It seemed to me that Berton's report must at any rate provide a key to the mystery. What strange happening could have had such a shattering effect on a veteran space-pilot? I began to search through the books once more, but The Little Apocrypha was not to be found. I was growing more and more exhausted and left the room, having decided to postpone the search until the following day.
As I was passing the foot of the stairway, I noticed that the aluminum treads were streaked with light falling from above. Sartorius was still at work. I
