Gregor waved a hand, And…?
“Our best guess of the value of the rest of the items inventoried and removed so far—as of this morning; I checked on the way here—is”—Galeni cleared his throat, unaccountably dry—“three point nine billion marks.”
Make that accountably dry, Ivan corrected his observation. Gregor, who had hitched himself up on the edge of the comconsole table, nearly fell off it. Shiv Arqua rubbed his forehead, his face screwing up like a man suffering from the sharpest twinge of existential pain in history.
“Almost four billion marks, Duv?” choked Gregor. “Really?”
“So far. We hope to have cleared the upper floor by the end of the week. I have absolutely no idea what we’ll find on the lower one.”
“More of the same, as I recall,” murmured Lady ghem Estif.
Silence fell throughout the room, as everyone present paused for a bit of simple arithmetic.
“I would note in passing,” observed Duv, recovering his driest professorial tones, “that the current value of the art and artifacts is very much higher that the, what one might call street value, would have been a hundred years ago. Appreciation, in both senses. Yet quite a number of people must have known what was in there, because it certainly took more than one man to fill it up. I really have no idea why no Cetagandan entrepreneur has been back since.”
Lady ghem Estif gave a muffled sniff, dulcetly, and waited.
Gregor opened his hand to her, a bit ironically. “Enlighten us, milady, if you please.”
“Because most of the items were the property of the ruling ghem-junta, and most of the ghem-junta were executed upon their return to Eta Ceta,” said Lady ghem Estif. She added, “They had planned to be back in person, of course.”
Ivan had no idea if it was the historian or the security analyst ascendant in his hungry tones, but Duv said, “I do hope you’ll have time to chat with me later, Lady ghem Estif.”
She held up her own hands, palm out, in a gesture that had little to do with surrender. “That will not be up to me.”
“Thank you, Commodore Galeni, that will do for now,” said Gregor. “Colonel Otto, do you have a, perhaps, fuller and more detailed account than your preliminary one of why my Imperial Security building is now largely an underground installation? From a technical perspective.”
Since Ivan recalled, among the cries coming from the command post the other day, some anguished engineering bellows of It sank! It sank! The sucker just sank! he suspected Otto did.
Galeni stood down and Otto came up.
“Sire.” His nod to Gregor was very respectful; his glower at the Arquas, not. “We’re still modifying details of our picture as new data come in, but I think what I have here is a correct general outline.” He shoved a data chip into the read-slot on the comconsole table; a large-scale, three-dimensional image in outlines of colored light sprang into view above the vid plate.
Otto gestured with a lightstick. “Ground-lines in dark brown, surrounding buildings in light brown. ImpSec building in green.” All six floors and the several subbasements, a boxy cage of cold-light-hued lines. “The bunker.” Another short stack of boxes in blue, cattycorner to the one in green. “The old storm sewer.” A translucent tube of red light, running at a diagonal far under the street. “We suspect Sergeant Abelard’s old tunnel might have had its start-point from the storm sewer, by the way. It’s possible that a patch there might have provided a weak point”—a darker red blob, with uncertain dotted outlines—“that blew out when the bomb”—an ominous purple pinpoint, accurately placed as far as Ivan could tell—“went off.”
“As much of the remaining Mycoborer tunnels as we could map.” Starting as a solid yellow tube descending from the garage under the office building across the back corner; a second, solid end snaking back from the vestibule hugged up next to the bunker.
“Our current best guess of what existed in between the two ends prior to the bomb blast.” Dotted yellow outlines, branching and re-branching directly under the ImpSec subbasements.
“The Mycoborer walls appear to cure very hard, strong in compression but weak in tension, and brittle. At some point during the firefight between the criminals and the ImpSec guards who pursued them underground, someone’s stray stunner beam struck the old bomb on the tunnel floor, setting it off.” Scrupulously, Otto’s picture did not suggest whose stunner this triggering energy pulse came from. A flare of purple light filled the tunnel network. “The air and gasses in the tunnels transmitted a strong concussion to the walls throughout; we don’t yet know if there was further chemical reaction. The stretching in tension cracked and in some places shattered the walls, both visible and micro cracks. At the same time, the weak portion of the storm sewer abutting or closely abutting the Mycoborer tunnel blew out, a section of the drain just down from the breach collapsed, the water so dammed diverted through the breach, and the shattered tunnel began to rapidly fill. Water not being compressible, this actually helped keep the network from collapsing for quite some time. Water from the on-going heavy rain drainage further penetrated and weakened the cracked walls, and began mixing under considerable pressure with the formerly dry and solid subsoil. In effect, the branching Mycoborer tunnel turned into a giant sponge under the ImpSec Headquarters.” A bulky, irregular region under the green cage filled with red light. “The pressure mounted.” The red light grew more intense; the sponge swelled.
Both Illyan and Allegre had exactly the same expressions of horrified fascination on their faces, Ivan noted in a brief look around.
“At the time that my engineers dug down to the bunker roof with grav-lifters”—a white circle appeared on the ground level of the park, and grew downward to the blue box in a neat cone—“possibly at the moment that we cut through the roof, the storm sewer unplugged itself. I suspect, but can’t prove yet, that the vibrations from our rescue work might have helped that along. In any case, the sewer unplugged and began draining the Mycoborer tunnel network of what was now a hell of a lot of liquid mud. The ImpSec building directly above acted as a giant weight, compressing the sponge and expressing its contents out the newly opened exit channel.”
Pulses of red light marched down the storm sewer.
“And the rest”—Otto sighed—“we all witnessed.” Slowly, as the red sponge flattened, its filaments collapsing, the green cage began to sink below the brown ground lines.
“How far down d’you think we’ll end up?” asked General Allegre, from his back row.
“Not much farther, I think. A man should just about be able to jump off the roof to the ground. Without breaking his legs, that is.”
A little silence followed this word-picture. If Allegre contemplated suicide over all of this, he was going to have to find another method than the traditional parapet, Ivan reflected. Gregor stirred himself and broke the hypnotized hush with, “Thank you, Colonel Otto, that was very clear.”
“Thank you, sire. But the big question I want answered”—he pointed to the sewer line—“we know damned well that bits of Mycoborer tunnel walls had to have been mixed with the mud. Which has mostly ended up in the river. What’s it doing downstream?” His glare at the Arquas was impartial, but far from impassive.
“For the answer to that question, I hope Dr. Weddell will have more information than this time yesterday. Doctor?” At Gregor’s gesture, Otto stood down and Weddell took his place.
