"On it," the com officer replied, and Tribeca's frown deepened.
"A com laser? From who?"
"That's just it, Skip." The tac officers fingers redirected her own passive sensors as she replied. "I don't see anything. If it's a com laser, it's awful low power, and I'm just catching a trickle now and then."
"It's intermittent?" Tribeca's brow furrowed, and the tac officer nodded
"I've got it, too, Sir," the com officer said. "Zero-eight-eight." He frowned and adjusted a rheostat carefully. "It's a com laser, all right. We're just catching the fringe of it. If I had to guess, I'd say there's a glitch in the sender's tracking systems. Not much of one—the beam's only kicking a little—but enough to swing it intermittently our way. It's scrambled, too... and I don't recognize the scramble code."
"What?" Tribeca shoved himself out of his chair and moved quickly to the tac station. "You don't see anything out there, Becky?"
"No, Sir. Whatever it is, it's running silent and too far out to find on passives. Should I go active?"
"Wait." Tribeca rubbed an eyebrow furiously, the exercise forgotten. Arrowhead was over ten light-minutes from the nearest senior officer. If he passed the buck, he'd give whoever was on the other end of that laser at least twenty minutes to coast out of active sensor range while he awaited orders, and he had no idea what the bogey's vector might be. But he did know the bogey wasn't Manticoran—not if Hal couldn't ID its scramble code.
He dropped back into his command chair and depressed a stud.
"Engineering, Lieutenant Riceman," a voice said.
"Rice, this is the Captain. We're about to go to battle stations." He heard someone inhale sharply on the bridge and ignored it. "Forget the exercise. How quick can you bring the wedge up for real?"
"Eighty seconds and you're hot, Skipper," Riceman said flatly, and Tribeca nodded.
"Get ready, then," he said, and looked back at the tac officer. "I want you to take us to battle stations on my command, Becky, but leave fire control and sensors on standby. Whatever this is, it's in range for a com laser. It could also be in energy weapon range, so I don't want any active emissions until the wedge and sidewall come up. Got it?'
"Yes, Sir. What about Attack, Sir? She'll be a sitting duck without her wedge if someone takes a shot at her."
"Agreed, but if whoever's out there knew we were here, they wouldn't have been transmitting in the first place, so I don't think they've got us on passive, either. If I'm right, they'll be too busy looking at our big, noisy emissions signature to notice Attack before she figures out something's going on and gets her own wedge up. Just the same, Hal," he looked at the com officer, "lay a laser on her and order her to action stations as soon as our wedge goes up."
"Aye, aye, Sir."
"All right, then, Becky. Battle stations!"
"Contact!" Alexander's tac officer shouted. "I have an impeller wedge, bearing one-three-six by oh-niner-two!" He slapped keys on his console. "Manty destroyer at eighteen million klicks, Captain!"
"Shit!" Commander Trent slammed a fist into the arm of her command chair. "Battle stations, but do not go active! Confirm!"
"Do not go active, aye." The tac officer confirmed the order even as Yasir Raven's thumb jammed down on the battle stations alarm. Staying in passive meant the cruiser couldn't bring up her impeller wedge or sidewalls, but it was still remotely possible that they hadn't been detected, and—
"Radar pulse!" Tactical snapped through the yowl of the alarm. "They've got us, Ma'am!" He paused, then, "Second drive source detected! Two destroyers at eighteen million klicks!"
Trent bit back another curse. At that range and on that bearing, there was only one reason for a Manty to suddenly light off his drive. Damn the luck! What the hell had they been doing lying doggo in just the right place for her com beam to hit them?!
"Vector change," Tactical announced in a taut voice. "They're coming to an intercept course, Ma'am. Acceleration five-two-oh gravities."
"Bring the wedge up." Trent turned to her astrogator. "Plot your translation, Jackie, and execute a random vector change the minute we cross the wall. I want us out of here the instant the generators spin up."
"Aye, Ma'am. Feeding the plot now."
"Impellers nominal, Captain!"
"Helm, turn us away from them. Come to one-two-five level and roll port."
"Aye, Ma'am. Coming to one-two-five level and rolling port."
Trent turned back to her display, glaring at the brilliant dots of the Manticoran destroyers. Barely a light-minute, right in her goddamned lap. They were too far out to engage her—even assuming they were confident enough of their ID to class her as definitely hostile—but the damage was done.
She made herself lean back, mouth tight, and drummed on the chair arms. There was going to be hell to pay for this, and whatever else came of it, all the shit in the galaxy was about to come down squarely on her head.
"She's gone active," Tribeca's tac officer reported, her voice almost dreamy with intensity. "Looks like a Conqueror-class light cruiser, Sir. She's altering vector away from us."
"Any chance of engaging her?" There was more hope than expectation in Tribeca's voice, and she shook her head.
"Sorry, Sir, no joy. She's way outside our missile envelope, and she's rolling to bring up her belly bands."
"Damn," the commander murmured. He watched his own display, ignoring the confused questions rattling over the com from Attack's skipper, while the Peep cruiser spun still further away from him. She was piling on the accel, too, and this far out—
The impeller source vanished in the sparkle of a hyper footprint, and he grunted. So much for catching her.
"Cut the accel, Helm." He shoved himself more firmly into his cushioned chair while his brain raced. "Hal, get off a contact report to Captain Edwards with all of Becky's data. Repeat it to Admiral Parks."
"Aye, aye, sir."
The bridge lift hissed open to admit his vacsuited exec. The execs skin suit looked out of place on the bridge, for there'd been no time for the duty watch to suit up, and Tribeca grinned scurry as he saw his own suit over the exec's arm.
"Thanks, Fred, but I think it's all over."
"What's all over?" the exec demanded in exasperation. "I hope you realize we just blew off the whole exercise, Skipper!"
"I know, I know." Tribeca stood and crossed back over to the tac station to watch the entire bizarre incident replay itself. "What do you think that was all about, Becky?"
"Well," the tac officer leaned back and scratched her nose, "the one thing I can tell you for sure. Sir, is that she was way too far out to pick up anything from the inner system on shipboard sensors. Add that to the fact that she was hitting something with a com laser, and—" She shrugged.
"But how in hell could they have—?" Tribeca shook his head. He couldn't quite believe the Peeps had some sort of stealth system RMN sensors couldn't penetrate, but as Becky said, that cruiser had been lasing something. And since his own sensors still didn't show anything for that something to have been, the empirical evidence said they did have a stealth capability far better than ONI had ever guessed.
"Helm," he said, still staring down at the tactical display, "put us back where we were when we picked up the first trickle, then come to zero-eight-eight. Take it slow, I don't want to overrun anything."
"Aye, aye, Sir. Reversing course now."
"Good." He put his hand lightly on the tac officer's shoulder. "If there really is something out here, it's going to be harder than hell to spot, Becky. Don't make any assumptions about Peep systems capabilities. Pretend it's something of ours that doesn't want to be found, then find it."
