"Invoke the most senior if you have to."

Sighing, Dorteka started to go into touch.

"Dorteka. Wait. Find out which outposts were silenced. And where that darkship went down."

"Yes, mistress," Dorteka replied.

"Sarcasm does not become you. Hurry. Before those fools panic and run away."

Dorteka went into touch. Her strained, twisting face betrayed her difficulty getting through, then an argument ensuing. Marika told Grauel, "If those fools don't come across, I'll hike down there and take a darkship myself. Why did they put Educan in charge? She is worse that Paustch ever was. She couldn't ... " Dorteka had come out of touch. "What did they say?"

"The darkship is coming. I had to lie, Marika. And I had to invoke Gradwohl. I hope you know what you are doing."

"What state were they in?"

"You can guess."

"Yes. Educan was packing. Grauel. Get my coats, boots, and weapons." On the frontier Marika dressed as one of the huntresses, not as silth.

Dorteka studied a map while Marika dressed. Marika glanced over her shoulder. "A definite progression, yes?"

"It does look like a developing pattern."

"Looks like? They will hit here next, then here, here, and then try Akard. No wonder Educan is in a dither. They will reach the Hainlin before dawn tommorow."

"You have that look in your eye, Marika. What are you going to do?"

No particular thought went into Marika's answer. "Ambush them at Critza." It was the thing that had to be done.

"They would sense our presence."

"Not if we use our novices to keep our body heat concealed."

"Marika ... "

"We will hit them on huntress's terms initially. Not as silth. They will not be looking for that. We will chew them up before they know what is happening."

"Critza is not inside your proper territory."

"If we do not do something, Educan will run off and leave us here. The Serke will not have to come after us. They can leave us to the grauken if they take Akard."

"True. But-"

"Perhaps one of the reasons Gradwohl favors me is that I am not bound by tradition. Not if form's sake means sticking my head into a kirn's den."

"Perhaps."

"Contact the outposts. We will gather everyone. Grauel. Prepare for two days of patrol for the whole force."

III Marika kept the darkship aloft continuously, bringing huntresses to Critza, till she felt the Serke party could be within an hour of her ambush. The western outposts had fallen as she had predicted. Akard was in a panic. The leadership there had so wilted, Marika no longer bothered trying to stay in touch.

A pair of darkships raced over, fleeing south, practically dripping meth and possessions. "That," Marika observed, "is why we silth are so beloved, Dorteka. Educan has saved everthing she owns. But how many huntresses and laborers were aboard?"

Dorteka did not try to defend Educan. She was as outraged as Marika was, if not quite for the same reasons. The Akard senior's flight was indefensible on any grounds.

"Everyone in place?" Marika asked. There were no tracks in the snow, nothing to betray the ambush physically. The huntresses had dropped into their positions from the darkship. "See if you can detect anybody, Dorteka. If you do, get on the novice covering." She could detect nothing with her own less skillful touch.

Fear proved to be a superb motivator. The novices hid everyone well.

"That is it for Chaser," Marika said as the last of the major moons settled behind the opposite ridge. But there was light still. Dawn had begun to break under a rare clear sky. Long shadows of skeletal trees reached across the Hainlin. The endless cold had killed all the less hardy. They were naked of needles. Occasionally the stillness filled with the crash following some elder giant's defeat in its battle with gravity. Farther north, where the winds kept the slopes scoured of snow, whole mountains were scattered with fallen trees, like straw in a grain field after harvest.

A far hum began to build in the hills opposite Critza. "Utter silence now," Marika cautioned. "Total alertness. Nobody move for any reason. And hold your fire till I give the word. Hold your fire." She hoped it would not be much longer. The cold gnawed her bones. They had dared light no fires. The smell of smoke would have betrayed them.

A machine thirty feet long and ten wide eased down the far slope, sliding between trees. It slipped out onto the clear highway of the rivercourse, surrounded by flying snow. For a moment Marika was puzzled. It seemed like a small darkship of odd shape, floating above the surface. It made a great deal of noise.

Then she recalled where she had seen such a vehicle. At the tradermale station at Maksche.

Ground-effect vehicle. Of course.

A second slithered through the trees, engine whining as it fought to keep from charging down the slope. Marika silently praised Grauel and Barlog for having established superb discipline among the huntresses. They were waiting as instructed.

They dared not open fire till all the craft were in the open.

She could see meth inside them, ten and an operator for each of those first two. At a guess she decided two silth and eight fighters aboard each. And definitely not nomads.

What had Bagnel told her about ground-effect vehicles? Yes. They were not sold or leased outside the brethren. Ever.

This ambush would stir one hell of a stink if she pulled it off.

A third and fourth vehicle left the forest. These two appeared to be supply carriers. No heads were visible through their domes, only unidentifiable heaps.

A fifth vehicle descended the slope, and a sixth. And still those already on the river hovered, waiting.

Marika ground her teeth. How much longer could fire discipline hold among huntresses already badly shaken by what faced them?

Not long. As the eighth vehicle appeared, making four carrying meth and four carrying supplies, a rifle cracked.

The huntress responsible was a competent sniper. Her bullet stabbed through a dome and killed an operator. The vehicle surged forward, gained speed rapidly, rose, and smashed into a bluff a third of a mile upriver. Its fuel exploded.

Long before that happened Marika's every weapon had begun thundering at the Serke. For a while the vehicles were hidden by smoke and flying snow.

Two more vehicles came down into the storm of death.

"Get that darkship up over the trail," Marika snapped at the Mistress of the Ship. "Wait. I am going with you. I do not want you following Educan. Dorteka. Keep hitting them. Get the personnel carriers first."

A vehicle broke out of the fury and scooted away north, sideslipping around the burning vehicle upstream. "That was a transport. We will catch it later. Take it up."

The darkship rose. At a hundred feet Marika could see that the remaining craft had been disabled. Huntresses had come out of some and were returning fire.

A fuel tank blew, spread fire to other crippled vehicles. The conflagration generated a battle between volatile fuel and melting snow. Burning fuel spread atop the running melt.

Marika reached with her touch and found several silth minds among the survivors, all bewildered, shocked, unready to respond. She jerked back, ducked through her loophole, grabbed the first suitable ghost she found, and hurtled down there. Slap. Slap. Slap. She dispatched three silth.

There were at least four more vehicles in the forest, all carrying silth and huntresses. They had halted. Marika flung herself that way, hammered at silth hearts and minds till she encountered one that hurled her back and nearly broke through her defenses.

She ducked back into the world long enough to order the darkship forward. The bath carried automatic weapons and grenades. She would wrestle the Serke sisters while the darkship crew demolished them with mundane weapons.
