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.
Unusual, yet pleasing to the eye, and he nodded in slow understanding. Even in emergencies, the Dinochrome Brigade didn't pick dummies as Bolo commanders. Major Stavrakas must have realized she'd been marooned here, and it seemed she'd decided that if Santa Cruz was to be her final duty station, she could at least make the depot as homelike as possible.
He shook himself and smiled in appreciation of Stavrakas' taste and, assuming all of this was her own work, artistic talent. Then he crossed to the central computer console, reached for the keyboard... and jumped ten centimeters into the air when a soft, soprano voice spoke abruptly.
'Warning,' it said. 'This is a restricted facility. Unauthorized access is punishable by not less than twenty years imprisonment. Please identify yourself.'
Merrit's head snapped around, seeking the speaker which had produced that polite, melodious voice. He didn't see it, but he did see the bright red warning light under the four-millimeter power rifle which had just unhoused itself from the wall above the console to aim directly between his eyes. He stared into its bore for a long, tense second, and the voice spoke again.
'Identification is required. Please identify yourself immediately.'
'Ah, Merrit,' he said hoarsely, then licked his lips and cleared his throat. 'Captain Paul A. Merrit, Dinochrome Brigade, serial number Delta-Bravo-One-Niner-Eight-Zero-Niner-Three-Slash-Five-Bravo-One- One.'
'You are not in my personnel files, Captain,' the soprano remarked. He started to reply, but the voice continued before he could. 'I compute, however, a probability of niner-niner point niner-niner-three percent that those files are no longer current. Query: Have you been issued a file update for me?'
Merrit blinked in disbelief. Even the current Mark XXV Bolo retained the emotionless vocoder settings of the earlier marks and normally referred to itself in the military third person except to its own commander. This voice, however calm and dispassionate it might be, not only used first person but sounded fully human. More than that, it carried what he could only call emotional overtones, and the nature of its questions implied a degree of discretionary autonomy which was impossible even for the Mark XXV except in Battle Mode.
On the other hand, he thought, still peering into the power rifle's muzzle, this was no time to be picky over details.
'Yes,' he said after a moment. 'I do have a personnel update for you.'
'Good,' the voice said-another response which raised Merrit's eyebrows afresh. 'Please understand that no discourtesy is intended, Captain, but the security of this installation requires that no unattested data be input to the
