The belly hatch opened, and Hoffman's head emerged.
"Pardon me, sirs. But do you hear that?"
They all listened for a moment, and Alek's ears caught a rushing sound below the engine's rumble.
"A stream?" he asked.
Hoffman grinned. "A noisy one, sir. Noisier than us, anyway."
"Excellent," Alek said, sitting up. "Up to half speed, Master Klopp?"
Klopp listened for another moment, then nodded.
Soon the Stormwalker was splashing down the stream, its engine noise mixing with the rush of water. The moon was higher now, the path shimmering in front of them. Volger was still up top watching for searchlights, but at least he wasn't standing on Alek's shoulders anymore.
The spray from the stream was icy; snow must still have been melting up in the mountains, even now in early August. Alek wondered how long they would have to stay in the Alps. He hoped Volger's mysterious preparations included a cabin with a warm fire.
The ground began to climb. They were nearing the rise where the land frigate stood guard. Alek lowered the engines back to quarter speed, and the Stormwalker became maddeningly lead-footed again. There were no sounds except the calls of night birds, the splashing of giant metal feet, and the babble of the stream.
Then a boot hit the back of his chair with a thump. "Volger! What are you - "
Something flashed in the darkness ahead. Alek froze, the walker pausing halfway through a step. He peered into the darkness.
"Should I shut the engines down?" he whispered.
"Don't!" Klopp said. "If they've spotted us, we'll need power."
Volger swung down from the hatch. "Germans! On foot, a hundred meters ahead. They haven't seen us. Not yet, anyway."
Alek swore softly, his hands flexing on the controls. He wondered which was worse, being spotted or sitting here frozen, like a rabbit waiting for a hawk to swoop. He leaned closer to the viewport, shielding his eyes. Something metal flashed in the darkness, and then he heard a shout.
"I think they just ...," he began.
Splashes of water sparkled white in the moonlight - a squad of infantrymen was running across the stream, shouting. One knelt on the bank and raised his rifle.
"... noticed us," Alek finished as a crack rang out. The bullet struck metal somewhere on the walker's body.
"Prepare to fire!" Klopp called through the intercom.
"No!" Alek said as his hands flicked across the controls.
"Alek's right," Count Volger said. "Those rifles might perk up the frigate's ears, but a cannon shot will remove all doubt. Just go through them."
The engines came to a roar beneath him, and Alek pushed the saunters forward. The Stormwalker's huge feet stretched out, splashing through the shallow water.
They charged up the stream, scattering the Germans like tenpins. A few bullets pinged off the armor as they passed, but Alek didn't bother to order the viewport closed. Vision was more precious than safety.
No stumbles now, no mistakes or they'd all be caught.
The moon had cleared the trees, the water shimmering in their path. A smile grew on Alek's face as he brought the Stormwalker into a run. Let the frigate try and catch them now.
No one could night-walk like him.
EIGHTEEN
THE FLARES CAME FIRST.
They screamed across the sky, burning phosphorous spilling a cold blue light into the darkness. The icy spray from the Stormwalker's footsteps glittered like diamonds scattered in the air.
More flares flew overhead, until the sky glowed with a dozen suns.
Flares and fireworks - not such secret weapons after all.
"Into the forest!" Klopp shouted.
Alek twisted the saunters hard, and the walker climbed the bank of the stream in a single step. It was darker up in the trees, the shadows shifting and dancing as the flares raced overhead.
But there were no more rifle shots, no thud of cannon fire.
"What's happening, Count?" Klopp shouted.
"The frigate is turning," Volger called down. "She looks sluggish."
"Perfect!" Klopp said. "We caught her engines cold."
"But why isn't she firing?" Alek asked, veering the Stormwalker around an outcrop of bare rocks.
"Good question, young master. Perhaps they intend to capture you alive."
Alek raised an eyebrow. "Well, that's reassuring."
The ground became steeper beneath them, the walker's engines straining. Wider spaces opened up among the trees as the slope increased. It made walking easier, but Alek felt exposed in the jittery light of the flares.
"Which way to more cover?" Klopp called up.
Volger lowered himself into the cabin. "It doesn't matter."
"Why not?" Klopp cried.
"The frigate isn't our immediate problem." Volger leaned down next to Alek. "Bring us around. You need to see them. And load that cannon!" he shouted down the belly hatch.
Alek brought the walker into a tight turn.
From up here on the unsheltered slope, he could see the frigate on its hill, the eight legs slowly flexing as it awoke. Its gun turrets had already spun around, but Alek could see why they hadn't fired yet.
Climbing the slope behind them were a half dozen walkers unlike anything Alek had ever seen. They were four-legged craft, with a galloping stride like metal horses. A single crewman rode half inside each one, his head and shoulders emerging like a centaur's. The scout walkers' single headlights danced through the trees like fireflies.
Their only weapons were small mortar tubes mounted on the rear of the machines. As Alek watched, one blossomed with a cloud of smoke, shooting another flare into the radiant sky.
"Some new kind of scout," Klopp murmured.
"And perfect for tracking the likes of us," Volger said.
Alek frowned. "But those mortars won't even scratch us!"
"They don't have to," Klopp said, "as long as they keep us in sight. The frigate will be moving sooner or later."
"So what do we do?" Alek said, hands clenching the saunters. "Fight them now, while she's still warming up?"
Klopp thought for a moment. "No, keep moving. Maybe you can get us to the border faster than they expect."
Alek turned the walker back around and started up the slope again. He heard Volger preparing the Spandaus. The scout walkers' pilots were only half covered with armor. A few machine-gun bursts might make them think twice about following too closely.
