“That’s an idea.” Ken was promptly lost in enthusiasm again. “As long as it’s cold enough, which is easy in this system — and Three has a satellite — you showed it to me. We can go there in no time in the Karella —and we could pick up that suit in space while we’re at it. Collect Feth, and let’s go!”

“I fear Feth will not be available for a while,” replied Drai. “Also,” he grimaced, “I have been on that satellite, and its soil is mostly pumice dust; it might have come straight from the Polar Desert on Sarr. We’d better consider the other possibilities before we take off. The trouble is, all we’ve ever noted about the other planets of the system is their motions. We wanted to avoid them, not visit them. I do remember, I think, that Five and Six do have atmospheres, which I suppose writes them off the list. You might see where Four is just now, will you? I assume you can interpret an ephemeris.”

Ken decided later that courtesy was really a superfluous facet of character. Had it not been for the requirements of courtesy he would not have bothered to make an answer to this suggestion, and had not most of his attention been concentrated on the answer he would never have made the serious error of walking over to the cabinet where the table in question was located, and reaching for it. He realized just as he touched the paper what he was doing, but with a stupendous effort of will he finished his assurance that he could read an ephemeris and completed the motion of obtaining the document. He felt, however, as though a laboratory vacuum pump had gone to work on his stomach as he turned back to his employer.

That individual was standing exactly where he had been, the expression on his face still inscrutable.

“I fear I must have done our friend Feth an injustice,” he remarked casually. “I was wondering how you had come to imply that a round trip to Sarr would take only a week. I realize of course that your discoveries were made quite accidentally, and that nothing was farther from your plans than vulgar spying; but the problem of what to do about your unfortunate knowledge remains. That will require a certain amount of thought. In the meantime, let us continue with the matter of Planet Four. Is it in a convenient position to visit, and could we as you suggested pick up the torpedo carrying your suit without going too far from course?”

Ken found himself completely at a loss. Drai’s apparently unperturbed blandness was the last attitude he expected under the circumstances. He could not believe that the other was really that indifferent; something unpleasant must be brewing between those steady eyes, but the face gave him no clue. As best he could he tried to match his employer’s attitude. With an effort he turned his attention to the ephemeris he was holding, found the proper terms, and indulged in some mental arithmetic.

“The planets are just about at right angles as seen from here,” he announced at length. “We’re just about between the sun and Three, as you know; Four is in the retrograde direction, roughly twice as far from us. Still, that shouldn’t mean anything to the Karella”

“True enough. Very well, we will take off in an hour. Get any equipment you think you will need on board before then — better use engineering armor for Planet Four, even if it doesn’t have air. You’ll have to point out where they are to whomever I get to help you.”

“How about Feth?” Ken had gotten the idea that the mechanic was in disgrace for betraying the secret of their location.

“He won’t be available for some time — he’s occupied. I’ll give you a man — you can be picking out what you want in the shop; I’ll send him there. One hour.” Laj Drai turned away, intimating that the interview was at an end.
