I gave him my best grin. "You are closer than you know. O.K., I'll lay off. You handle your end of it and I'll handle mine."
"A fair exchange is no bargain. Go, and sin no more."
"I'll buzz you back before I go in," I said, and hung up.
Playing games inside a crowded asteroid is not the same as playing games in, say, Honolulu or Vladivostok, especially when that game is a combination of hide-and-seek and ring-around-the-Rosie. The trouble is lack of communication. Radio contact is strictly line-of-sight inside a hunk of metal. Radar beams can get a little farther, but a man has to be an expert billiards player to bank a reflecting beam around very many corners, and even that would depend upon the corridors being empty, which they never are. To change the game analogy again, it would be like trying to sink a ninety-foot putt across Times Square on New Year's Eve.
Following somebody isn't anywhere near as easy as popular fiction might lead you to believe. Putting a tail on someone whose spouse wants divorce evidence is relatively easy, but even the best detectives can lose a man by pure mischance. If the tailee, for instance, walks into a crowded elevator and the automatic computer decides that the car is filled to the limit, the man who's tailing him will be left facing a closed door. Something like that can happen by accident, without any design on the part of the tailee.
If you use a large squad of agents, all in radio contact with one another, that kind of loss can be reduced to near zero by simply having a man covering every possible escape route.
But if the tailee knows, or even suspects, that he's being followed, wants to get away from his tail, and has the ability to reason moderately well, it requires an impossibly large team to keep him in sight. And if that team has no fast medium of communication, they're licked at the onset.
In this case, we were fairly certain of Jack Ravenhurst's future actions, and so far our prophecies had been correct ... but if she decided to shake her shadows, fun would be had by all.
