He and Anne were driving west when the brilliant flicker of laser fire began to light up the evening sky.
"Green Mountain lasers firing!" someone snapped from across the situation room.
"Where?" Bailey snapped back, pushing past Ramirez as he sprinted over to the defense station.
"North fence," the tech reported, bizarrely colored images flashing across his displays as he sorted through the various monitor images. "No speed—no metal—small explosives—"
"Got it," his neighbor said, and a full view appeared on the main monitor display.
Bailey felt his jaw drop. "Balloons?"
The words were barely out of his mouth when another pair drifted above the fence and vanished as the defense lasers targeted them. "Yes, sir," the tech confirmed. "They're helium-filled balloons" —a pair of small flickers of fire appeared at the top of the fence itself— "with small explosives tethered underneath."
"What in the world are they trying to do?" Ramirez muttered from Bailey's side. "They can't get explosives into Athena that way. Can they?"
"They shouldn't be able to," Bailey agreed, one of the recorded conversations between Poirot and Skyler flickering through his mind. It couldn't be very much bigger than primer cap size, though. Unless you know some trick about that?
These explosives were indeed primer-cap sized. But the balloons delivering them were much larger, obviously large enough to trigger the defenses. Had Skyler thought the lack of metal or high-speed movement would let them slip over the wall? There was another multiple flicker from the lasers, and another set of small explosions from the top of the fence.
The fence.
"Security units to the north fence," he snapped toward the duty officer near the door. "Double-time it."
"What is it?" Ramirez asked, his head turning back and forth as he looked between the various displays.
"They're not trying to get those blasting caps into Athena," Bailey bit out from between clenched teeth.
"They're trying to knock out the wall's targeting sensors."
"But they can't do that," Poirot protested. "Can they?"
"There!" the tech snapped, pointing to the display as something dark shot out and up from a window in one of the buildings across the wide open area outside the wall, trailing a thin rope or cable behind it. It hit the top of the fence and stuck, its trailing rope pulling taut. "Colonel?"
"I see it," Bailey gritted, turning to the two Ryqril. "It's a grappling hook, Your Eminences."
"'Rotect at runce," Halaak bellowed. The big khassq had his laser pistol out now, swinging it around the situation room as if looking for a target.
"Security forces on their way, Your Eminence," the duty officer called, his voice cracking a little as the Ryq's waving laser pistol waved his direction. "But it'll be several minutes before they can get there."
"Several minutes may be too late," Bailey said, staring at the image on the display. The tiny bombs were still peppering the top of the fence, wrecking or confusing or stunning the sensors there, and two more grappling hooks had joined the first in attaching themselves to the damaged section. But so far there was no sign of the blackcollars themselves. "Battle Architect, I'd like your permission to pull back some of the ambush forces."
"No," Halaak snapped. "Re nust ca'ture the 'lackcollars."
"Just the ones the convoy has already passed," Bailey told him. "They're the ones closest to the north fence anyway. We can have them surround that house, maybe hit the blackcollars or Phoenix forces before they even get over the wall."
Daasaa nodded his head sharply. "Dae it," he ordered.
Bailey caught the duty officer's eye. "You heard him," he said. "Everyone the convoy has already passed is to converge on that building."
"Yes, sir."
"And keep an eye on those two Boulder bandits," Bailey added to the spotter controller. "If they're going to make a move against Athena, this'll be the time for it."
Convoy approaching, O'Hara's signal came.
Rear guard returning to fence, Flynn added. Spotters have been ordered to watch intruders.
And if the spotters were keeping an eye on each other, Skyler knew, they would have that many fewer eyes focused on the drama about to unfold beneath them. So far, everything was going according to plan.
He looked across the street, where Kanai was peering at him over the edge of the taller building there.
Catching his eye, Skyler gave him a thumbs-up, then turned and did the same to Hawking, twenty meters away on Skyler's same rooftop. Alert blockers, he signaled O'Hara.
Blockers ready.
Skyler took a deep breath and crouched down by the edge of the roof, flexing his fingers as he prepared for action. Any minute now ...
And then, there they were, coming down the wide street toward their rooftop positions: a car followed by six unmarked vans followed by another car. Just about as obvious as it was possible to be.
He looked down at the street. One of the quiet Security vans was parked half a block away, but all the sparse civilian traffic was out of the ambush zone. There were a few pedestrians strolling the walkways, but they should have time to get out before things got messy.
Stand ready, he signaled. The lead car passed his position, then the first van, then the second— Now.
And in response, a large tanker truck lurched into view from an alley ahead, pulling across the street directly in front of the convoy. Even as the cars and vans screeched to a halt, a second tanker turned a corner a street back and rolled into blocking position behind them.
"You're surrounded and outgunned," O'Hara's amplified voice called, the multiple echoes from the canyon of buildings making it impossible to tell where exactly the voice was coming from. "Come out, lay down your weapons, and surrender."
For a moment nothing happened. Then, in perfect unison, the car and van doors were flung open and drivers and guards spilled out onto the pavement.
Only it wasn't the two or three guards per prisoner that Poirot had said would be along for the ride.
Instead, there were nearly three dozen Security men in full riot armor now scrambling to take up defensive positions behind doors and at the sides of their vehicles, their paral-dart and flechette rifles pointed in all directions, including up. At the same time, the vans' sunroofs slid open and more Security men popped into view, this group cradling heavy laser rifles in their arms.
Mentally, Skyler shook his head. So very predictable. Fire, he ordered.
And with a muffled sploosh, each of the two tankers began spilling a thick, viscous fluid from beneath it, fluid that began flowing slowly down the street toward the convoy.
Two seconds later, both flows burst into brilliant, yellow-white flame.
It was even more impressive than Skyler had expected. The twin walls of fire moved ponderously toward the convoy and the crouched Security men, the flows' leading edges angling toward each other along the gutter on the east side of the street. Skyler couldn't see the Security men's faces or hear their conversation, but from their body language and the way their gun barrels were dipping he guessed they were suddenly reconsidering what they'd probably thought were pretty decent defensive positions. "I suggest you move, gentlemen," O'Hara prompted, the words barely audible over the crackling of the flames. "It's not likely to stop for you."
For a long moment nothing happened. Skyler had picked this spot with its topography in mind, and as he watched the two flows met up along the east side of the street, filling the gutter with flame and cutting off any possibility of retreat that direction. As the fuel pooled and the wall of flame widened, it began to fill the rest of the street, moving slowly but inexorably across the pavement toward the trapped vehicles.
