The inhibitory software had done just that, but at a price. Full integration of a Bolo’s personality had been possible only in Battle Mode. The division of its cybernetic and psychotronic functions into separate subsystems had been a deliberate part of design security intended to place the Bolo’s full capabilities beyond its own reach except in combat. Effectively, that reduced its “IQ” to a fraction of its total potential even at Normal Alert Readiness, for the huge machines simply were never fully “awake” outside combat. But because the Bolos’ autonomous functions operated solely in Battle Mode, they had, perversely, been more likely, not less, to go rogue if system senility set in. The only thing they’d known how to do on their own was to fight, after all, and if any failing system or corrupted inhibitory command file toggled their autonomy Merrit suppressed a familiar shiver at the thought of what a Bolo that thought its friends were its enemies could do. It hadn’t happened often, thank God, but once was too many times. That was the main reason the Dinochrome Brigade had spent decades hunting down abandoned and obsolescent Bolos from Mark XX to Mark XXIII and burning out their command centers. Hideously unpopular as that duty had always been with the personnel assigned to it, they’d had no choice. “Sleeping” Bolos were too dangerous to leave lying around, and the cost efficiency people had concluded (with reason, no doubt, if not precisely with compassion) that it would have been too expensive to refit the older Bolos’ psychotronics to modern standards.

All of which meant it was probably a very good thing no one on Santa Cruz had remembered this Bolo was here. If anyone had remembered and come hunting for salvage, or even just for a curious peek at the old site, Stavrakas’ Stand-By order would almost certainly have unleashed the Bolo on the “hostiles,” with catastrophic consequences.

He sighed and popped the skimmer hatch, then climbed out into the sound of Santa Cruz’s jungle wildlife with a grimace. In a way, he almost wished he were here to burn the Bolo’s command center. It always felt like an act of murder, but the fact that no one had even noticed that Stavrakas and Albright had died seemed a grim portent that this assignment was just as much the end of the road for him as he’d feared. Still, he supposed he should feel lucky to have even this much, he told himself, and sighed again as he reached for the bush knife Esteban had thoughtfully provided.

I rouse once more, and additional circuits come on-line as I realize this is not a regularly scheduled Alert cycle. The depot’s passive sensors report the approach of a single small vehicle, and I zero in upon its emissions signature. The forward recon skimmer carries a Navy transponder, but it has not transmitted the proper authorization codes before entering my security perimeter. I compare its transponder code to those stored in the depot’s files, and identification comes back in 0.00032 seconds. It is Commander Jeremiah Albright’s personal vehicle code, yet 0.012 seconds of analysis suggest that it cannot be Commander Albright. Were he still alive, Commander Albright would be one hundred twenty-four years, nine months, and ten days of age, Standard Reckoning, and certainly no longer on active duty. Accordingly, the pilot of the skimmer must be an unknown. It is conceivable that whoever he or she is has acquired the skimmer by unauthorized means-a possibility further suggested by the absence of any authorization code-in which case approach to this site would constitute a hostile intrusion.

My Battle Center springs to life as I recognize that possibility, but I initiate no further combat response. My autonomous logic circuits accept the possibility of hostile action, yet they also suggest that the skimmer does not possess the weapons capability to endanger a unit of the Line or the depot. Use of deadly force is therefore contraindicated, and I activate the depot’s external optics.

It is, indeed, a recon skimmer, though it no longer bears proper Navy markings. It has been repainted in civilian colors, obscuring any insignia or hull numbers, yet it retains its offensive and defensive systems, and I detect an active sensor suite. Moreover, the uniform of the pilot, while not quite correct, appears to be a variant of that of the Dinochrome Brigade. The piping is the wrong color, yet the Brigade shoulder flash is correct, and it bears the collar pips of a captain of the Line.

I study the face of the man who wears it. He is not listed in my files of Brigade personnel, but those files are seventy-nine years, ten months, eleven days, and twenty-two hours, Standard Reckoning, old. Once more, logic suggests the probability—on the order of 99.99 percent-that none of those listed in my files remain on active duty. A secondary probability on the order of 94.375 percent suggests that the uniform discrepancies I detect are also the result of passing time.

The captain, if such he truly is, approaches the main personnel entrance to the depot. He carries a bush knife, and, as I watch, begins to clear the local flora from the entry. Clearly he is intent on gaining access, and I devote a full 5.009 seconds to consideration of my options. Conclusion is reached. I will permit him entry and observe his actions before initiating any further action of my own.

It took forty minutes of hard, physical labor to clear the entry. Merrit was wringing wet by the time he hacked the last wrist-thick creeper aside, and he muttered a quiet curse at Santa Cruz’s damp heat. No doubt the planet’s farmers welcomed the fertility of its tropical climate, at least when they weren’t fighting tooth and nail against the plant life it spawned, but Merrit was from cold, mountainous Helicon, and he was already sick of the steamy humidity after less than six hours on-planet.

He deactivated the bush knife and scrubbed sweat from his eyes, then frowned in concentration as he keyed the admittance code into the alphanumeric pad. It was plain blind luck Central had even had the code. A portion of one of Major Stavrakas’ earlier dispatches had survived the Quern raid in what remained of Central’s high-security data core, and it had contained both the depot entry codes and the command codeword she’d selected for her Bolo. Without both of those, there wouldn’t have been enough brigadiers in the universe to get Paul Merrit this close to a live Bolo. He was no coward, but the notion of confronting something with almost four megaton/seconds of main battery firepower without the ability to identify himself as a friend was hardly appealing.

The depot hatch slid open with surprising smoothness, and he raised an eyebrow as the interior lights came on. There was no sign of dust, which suggested the depot remotes must be fully on-line. That was as encouraging as it was unexpected, and he stepped into the air-conditioned coolness with a sigh of gratitude. Someone had hung a directory on the facing wall, and he consulted it briefly, then turned left to head for the command center.

I note that the unidentified captain has entered the proper admittance code. This is persuasive, though certainly not conclusive, evidence that his presence is, in fact, authorized. I generate a 62.74 percent probability that Sector HQ has finally dispatched a replacement for my previous Commander, but logic cautions me against leaping to conclusions. I will observe further.

The command center hatch opened at a touch, and Merrit blinked at the non-regulation sight which met his eyes. Computer and communication consoles awaited his touch, without a trace of dust, and he was surprised to see the holo display of a full-scale planetary recon system glowing in one corner. Yet welcome as those sights were, they also seemed hopelessly incongruous, for someone had decorated the center. That was the only verb he could think of. Paintings hung on the ceramacrete walls and sculptures in both clay and metal dotted the floor. One entire wall had been transformed into an exquisite mosaic-of Icarus plunging from the heavens, unless he was mistaken-and handwoven rugs covered the floor. None of them impinged on the efficiency of the working area, but they were… nonstandard, to say the least.
