"In the place Jordan described. It's deep underground but I believe it's near one of the piles. I felt the wall and it was warm." "Somewhere below the gravity computer," said Docchi. "Why there, I don't know, but Nona may have had a reason. What I want to know is: how do you account for the ship?" "What?" said Cameron. "Oh, I leave that to you and Jordan. I can't explain it." Docchi guessed why the doctor was less concerned than he tried to be. Let him live with his exaltation for a while. It might not last. "Part of it's easy, how the ship came to be there." "It isn't to me," said Cameron. "We haven't been gone long, not much more than a month." "Six weeks to be exact. Six weeks on our calendar." "I see, relative time. I heard we were approaching the speed of light but I didn't think we were close enough to make any difference." He glanced at his watch as if it held secrets he couldn't fathom. "How long have we actually been gone, Earth time?" "I don't know. We haven't any figures on our acceleration rate nor our present speed." "What are you planning to do? We can't just sit here and let them overtake us." "I don't know. We're not helpless." Docchi's plans were vague. There was much that had to be determined before he could decide on anything. "You're certain it's one of ours? It's not an alien ship?" The idea hadn't occurred to Cameron. He turned the image around in his mind before he answered. "I'm not familiar with ship classifications, but it's ours unless these aliens use the English language. There was a name on it. I could read part. It ended in -_tory_." "The Victory class," said Docchi. "The biggest thing built. At one time it was intended for interstellar service, before the gravity drive fizzled." "That's how they were able to do it," said Cameron. "I've been wondering how they were able to send a ship after us so soon, even allowing for the fact that we've been gone longer than it seems to us, maybe two or three months instead of six weeks." He had nothing definite to go on but in Docchi's opinion the time was closer to half a year. "Right. Since the ships were already there rusting in the spaceport all they had to do was clean them up and add an information unit to the drive. They may have started work on it while we were in the solar system, when they were still looking for Nona." The special irony was that our own discoveries were being used against them. Nona's first, the resurrected drive, and then his own not negligible contribution. Docchi himself had told them. His thoughtless remark that the drive would function without Nona had been relayed back to Earth. Vogel the engineer had probably picked it up and sent the information on. Someone would have chanced on the idea anyway, but he had given them weeks. And a week was of incalculable importance--planets could be won or lost. Cameron was silent as they walked on. "There's a ship but we don't know where. Let's not worry until we find where it's going."
