methods, doubly so on the Metro's crowded, frantic rush-hour schedule. He was beginning to think that the most common means of transferring information, the dead-drop, wasn't part of this line. That, too, was very curious. There should have been at least one dead-tin, else the KGB could roll up the line-maybe
They were already trying to identify the source of the leak, of course, but they had to be careful. There was always the possibility that the spy was himself (or herself?) a security officer. That was, indeed, the ideal post for an intelligence agent, since with the job came access to everything, plus foreknowledge of any counterintelligence operations under way. It had happened before-the investigation of a leak had itself alerted the spy, a fact not discovered until some years after the investigation had been terminated. The other really odd thing was that the one photographic frame they had was not of a real diagram, but rather of a hand-drawn one
Handwriting-was that the reason that there were no dead-drops? The spy could be identified that way, couldn't he? What a foolish way to-
But there was nothing foolish here, was there? No, and there wasn't anything accidental either. If the techniques on this line were odd, they were also professional. There was another level to this, something that the interrogator didn't have yet.
"I think that tomorrow, you and I will ride the Metro."
Colonel Filitov woke up without a pounding in his head, which was pleasure enough. His "normal" morning routine was not terribly different from the other sort, but without the pain and the trip to the baths. He checked the diary tucked away in the desk drawer after he dressed, hoping that he'd be able to destroy it, as per his usual procedure. He already had a new blank diary that he'd begin with when this one was destroyed. There had been hints of a new development on the laser business the previous day, plus a paper on missile systems that he'd be seeing the following week.
On entering the car, he settled back, more alert than usual, and looked out the window during the drive into work. There were a number of trucks on the street, early as it was, and one of them blocked his view of a certain piece of curb. That was his "data-lost" signal. He was slightly annoyed that he couldn't see where it was, but his reports were rarely lost, and it didn't trouble him greatly. The "transfer successful" signal was in a different place, and was always easy to see. Colonel Filitov settled back in his seat, gazing out the window as he approached the spot there. His head turned to track on the spot, looking for the mark but it wasn't there. Odd. Had the other marker been set? He'd have to check that on the trip home tonight. In his years of work for CIA, several of his reports had been lost one way or another, and the danger signal hadn't been set, nor had he gotten the telephone call asking for Sergey that would tell him to leave his apartment at once. So there was probably no danger. Just an annoying inconvenience. Well. The Colonel relaxed and contemplated his day at the Ministry.
This time the Metro was fully manned. Fully a hundred Second Directorate men were in this one district, most dressed like ordinary Moscovites, some like workmen. These latter were operating the "black" phone lines installed along with electrical service panels throughout the system. The interrogator and his prisoner were riding trains back and forth on the "purple" and "green" lines, looking for a well-dressed woman in a Western coat. Millions of people traveled the Metro every day, but the counterintelligence officers were confident. They had time working for them, and their profile of the target-an adventuress. She was probably not disciplined enough to separate her daily routine from her covert activities. Such things had happened before. As a matter of faith-shared with their counterparts throughout the world-the security officers held that people who spied on their homeland were defective in some fundamental way. For all their cunning, such traitors would sooner or later connive at their own destruction.
And they were right, at least in this case. Svetlana came onto the station platform holding a bundle wrapped in brown paper. The courier recognized her hair first of all. The style was ordinary, but there was something about the way she held her head, something intangible that made him point, only
