Fire with Fire(39)

Smiling slightly, the second engineer snapped a toggle with his left forefinger. Clearly, the only possible reason that the engineer did not move to pursue Caine was because he had no intention, and therefore no reason, to do so.

Riordan felt himself lean toward that comforting thought, but fought back. No: the answer you like the most is the one you should trust the least. Go over the evidence one more time: be sure you haven’t missed something.

Downing had warned Caine to be watchful when he started back to Earth, and had provided special tools to help him watch: six near-microscopic AV bugs and the palmtop that also served as a receiver for the bugs’ signals. However, as on Dee Pee Three, what Caine found the most useful was his official security classification—the highest level of clearance among the nations of the New World Commonwealth bloc. Perhaps because Caine had never been conditioned to obey the unwritten rules of the intelligence community, he discovered a novel use for his access: locating and tapping dozens of covert operating funds. On every ship, the ample cash quickly made him a favorite with the bartenders, waiters, and restaurateurs in each hull’s ubiquitous core concourse, which was the only place where passengers from different hab mods were permitted to mingle. It also made the concourse the most logical site for an assassin to access a target—and therefore, a site that Caine had to watch closely.

So, furnished with all the friends that government monies could buy, Caine had made daily circuits around each ship’s concourse. After surreptitiously planting a micro-bug at each compass point of the main promenade, he slowed his pace, checking the palmtop’s screen for a figure that moved with him. Caine acquired no such shadow during the first shift to CD-49, nor at Epsilon Indi. Even upon arrival in Junction, Caine saw no suspicious repetition in the churn of new eyes, faces, profiles. He had begun to dismiss Downing’s warning—that Junction was the most likely point of intercept—when he sensed the first shadows of a threat stretch toward him.

A week before they were scheduled to transfer to the Commonwealth, the Tyne’s captain—an amiable Scot named Burnham—got on the shipwide at 0400 hours, apologized for waking everyone up, and then ordered everyone to strap in. Minutes later, acceleration cut out; the ship did a 180-degree tumble and initiated a day of unscheduled counterthrust in order to rendezvous with the Euro clipper Schnellwind, which was already stern-chasing the Tyne, sometimes at a punishing five gees. But the clipper’s passengers turned out to be a meager group of very shaken and very junior executives—whose jobs clearly did not warrant such high-speed transport—and a second engineer whose dossier was still “in transit” from his last posting. That last bit of information sent a cool fingernail of warning down Caine’s spine.

As if to confirm Caine’s worst fears, the second engineer appeared in the Tyne’s concourse soon after. Using the pre-positioned bugs, Caine watched the new bridge crewman trail him through two complete circuits of the crowded promenade, never closer than fifteen meters, never further than thirty.

Caine countered with a few calls to his fellow passengers on DPV 6. Ten minutes later, a convivial group had gathered at Le Café Viennese. The endless stream of champagne overcame (as Caine knew it would) one of his more susceptible neighbors: a jovial, undersized accountant returning to Earth from Zeta Tucanae. A ship’s steward was called to escort the revelers back to their hab mod, along with one member of the security watch, a Gold Coast Aussie by the name of Digger Mack. Caine remained at the center of this knot of unknowing rescuers until he was safely back in his suite. The next day, he bought a tour of Captain Burnham’s bridge with carefully underplayed flattery and complimentary bottles of Bollinger, and left behind another of his spy-eyes/ears, wedged in a crevice between two access panels. Then he holed up in DPV 6 and watched the second engineer cycle through his daily duties. And saw nothing even vaguely suspicious for five dull days.

Nothing even vaguely suspicious, Caine recited to himself as he entered the module access tube. Forty meters away, the watch officer manning the security checkpoint into hab mod DPV 6 waved for Caine to hurry. A closer look revealed the officer to be none other than the ever-affable Digger Mack. Caine took a final look at his palmtop. On the bridge, the second engineer continued in the casual execution of his tedious duties. The only unusual feature was his faint, unnervingly persistent smile. But what did that prove? Nothing. And besides, he can’t reach me anymore. So just accept that you are not going to see any danger signs—because there are none to be seen. Caine fished the transponder out of his shoulder bag. He slipped it back into his pocket, slightly horrified as he reflected upon the plot he had been prepared to carry out: how utterly bizarre, to save yourself by being ready to virtually kill yourself—
