"Not much. Thurston's men don't know what Baedecker is up to, as far as we can gather. But the Baedecker agents have an idea that Thurston is trying to take over Viking, and they don't mind at all; they're evidently hoping that the Ravenhurst-Thurston battle will create enough confusion so that it won't take much push on their part to topple the whole mess and take control. We know most of the regular agents on both sides, and we've managed to get a lot of that information to Colonel Brock so that he can handle quite a bit of the work for us." Marty chuckled a little. "That's what I call a _really_ secret agent. Brock has no idea that he's an agent for a service he doesn't even know exists." "Harrington Brock is a good man, Marty. Don't underestimate him." "I don't. It's a shame he just doesn't have quite what it takes to be good PSD material." "I hate to be referred to as 'material', good or bad. Do you have any idea how Baedecker or Thurston might be going to pull the grand-stand play?" "Not a one, so far. How about that robotics team, or the engineers who are working on the ship? Think any of them could be in the pay of a rival?" "It's possible," I said, "but I don't know which one or ones it might be. I've been watching them for three days, and they all seem on the up-and-up to me. And that worries me." "How so?" "You'd think that at least one of them would behave suspiciously by accident once in a while. You know--nerves or jumpiness from purely personal reasons. Hang-over, maybe, or woman trouble. But, no." "The clue of the dog in the night, huh? Does that mean you suspect all of them?" he asked dryly. "Sure. Isn't that what a good detective is supposed to do?" "I wouldn't know; I'm just an information post. I will say this, though: If any of that bunch is connected with either Baedecker or Thurston, he isn't a professional. He's someone who's been contacted secretly and offered a heavy bribe. We're checking back on all of them now, to see if there's anything in their pasts which might indicate that their ethics are not what they should be. Or any unusual circumstance that might indicate blackmail or financial pressure." "Nothing so far, though?" "Nothing." I thought for a second, then said: "Is there any known rival agent in any position to sabotage McGuire on Phobos, Mars, or Luna?" "Several, in each place. But we'll have agents there to keep an eye on them. To be honest with you, Oak, I don't think there's much to worry about. I don't mean you shouldn't keep your eyes open, but--" "I know what you mean," I said. "Do my own worrying, and don't worry you with it. All right. Meanwhile, if you get anything I can use, call me. And I'll let you know at this end." "Fair enough. Good luck." I wished him the same, and cut off. * * * * * I had time for one drag off my cigarette and one swallow of beer before the phone chimed. I put my beer down and pushed the switch for the audio only.
