Valiant

FOUR hours until contact with the Syndics. The Alliance fleet and the Syndic flotilla were less than fifty light-minutes apart, each force moving at point one light speed, their combined rate of closure at the point two light speed maximum for effective targeting. He could now see what the Syndic ships had been doing just less than an hour earlier, just as they could see the status of the Alliance fleet that long ago. It was still too early to set his combat formation, too early to let the Syndic commander know how Geary planned to meet the enemy.

“Captain Geary? There’s something we need to show you.”

He acknowledged the message from Captain Desjani and headed for the compartment she’d called from, trying not to look apprehensive as he passed members of Dauntless’s crew. Despite the need to concentrate on the upcoming battle, Geary had been constantly distracted by worries about what his internal enemies might do. It sounded like they must have tried striking again.

The compartment proved to be one of the primary-systems control stations, apparently confirming his fears. As the hatch sealed behind him, Geary saw Desjani, the lieutenant commander who was Dauntless’s systems-security officer, and the virtual presence of Captain Cresida. “What is it this time?”

Desjani and the lieutenant commander both looked at Cresida, who gestured toward some of the system modules behind her. “I’d been thinking, sir,” Cresida began. “Trying to figure out how the aliens could be tracking us. The business with the worms got me wondering about our systems, about whether anything else could be hidden in them.”

Geary frowned. “The aliens? This isn’t about a new worm generated from somewhere within the fleet?”

“No, sir. We found something that couldn’t have come from internal sources. We had to get Captain Desjani’s systems-security officer involved.”

“It couldn’t have come from the inside?” Geary gave Desjani and her systems-security officer a puzzled look. “But you found something else?”

Cresida nodded. “Yes, sir. What I was wondering was, if something else was there, something that let the aliens track our movements, how could it still be hidden? It would have to be something unlike anything we’ve used or tried to use if our security scans missed it. So I’ve been looking at different things, just off-the-wall stuff, seeing if anything unusual or unexpected showed up anywhere inside our systems.”

Desjani’s systems-security officer tapped a control, and a virtual display popped up beside him, showing a weird image of what looked vaguely like overlapping waves with fluctuating boundaries. “This shows commands being sent through the navigational system, sir,” he explained. “Not the code, but the actual electron signal propagation. It’s a representation, of course, rendered in terms understandable to us. What Captain Cresida found was that the commands had something else piggybacking on them.” He indicated the fluctuating tops and sides.

Cresida pointed to them as well. “I don’t know how they do it, but somehow they’re encoding a worm using self-sustaining probability modulation on a quantum scale. Every particle making up this signal has quantum characteristics, of course. Well, the aliens have imprinted some kind of program on those characteristics. I know it’s not natural because there should be probabilistic variation in how these actions are occurring on the quantum boundaries of the particles making up the signal. There isn’t. It’s following patterns. We can’t tell what those patterns do, or how they do it, but it’s definitely something that shouldn’t be there.”

Desjani nodded toward the display. “We think we’ve found our alien spy, Captain Geary.”

“I’ll be damned. This is in the navigational systems?”

“And the communications systems. We’re still screening the other systems but haven’t found anything like it, yet.”

Geary stared at the display, amazed. “It’s set up to know where we’re going and tell someone else. Can this thing send messages at faster-than-light speeds?”

Cresida made a frustrated gesture. “I don’t know! I don’t know how it works at all, let alone what it can do. I just know it’s not supposed to be there.”

The lieutenant commander spoke up. “Naturally, none of our security programs or firewalls could spot this. It’s, uh, alien to them, if you’ll pardon the term.”

“There’s nothing we can do about it?” Geary demanded. “We just have to leave this thing infesting our systems?”

That drew a fierce smile from Cresida. “No, sir. I may not know how it works, but I know how to kill it.”

“That’s the first time I ever heard you talk like a Marine, Captain Cresida. How do we kill it?”
