"It doesn't explain the Night Warrior," Will pointed out, and Alyss smiled at him.
"Perhaps not. But if he were real, why bother with trick lights?" she said. "Odds are he was another trick-even less substantial than the lights, judging by the dog's reaction. Now show me exactly where you were when you saw it."
She led the way back to where Tug waited on the main trail The little horse looked at them quizzically, as if wondering what he'd missed. Will reached up to the bedroll behind the saddle and untied it. Alyss watched curiously as he withdrew the component parts of the recurve bow. He fitted them together and strung the bow in a series of deft movements. Then he tested the draw and met her gaze with a look of fierce satisfaction.
"That's more like it," he said, laying an arrow on the string. "If we're going looking for this damn Night Warrior, I'd rather do it with a bow in my hands."
He led the way forward until they reached the edge of the mere. Even by daylight, it was a sinister place, with curtains of mist rising from the far side. The water itself was like black marble, smooth and impenetrable to the eye. Bubbles rose to the surface further out, hinting at the presence of creatures lurking below in the depths.
"Here," Will said. "As near as I can remember. And the figure was out there… toward the far side of the mere."
Alyss looked shrewdly in the direction he indicated, then looked along the edge of the mere, where the path ahead of them followed the bank. At one point, it cut inside a small promontory, covered in trees and shrubs.
"Let's take a look over there," she said.
Will followed her, his curiosity mounting. "What have you got in mind?" he asked. It was clear to him that Alyss had formed a theory of some kind. But she held up a hand to forestall his questions.
"It's just an idea," she said vaguely. Her eyes were searching the ground ahead of them and to either side of the path. "You're better at this than I am," she said. "Check the ground in any clear spot."
Will complied, his trained tracker's eye running over the ground. There was faint evidence that someone had been there before them-perhaps as recently as two nights ago, he thought.
"Am I looking for anything in particular?" he asked, his eyes quartering the ground.
"Scorch marks," said Alyss, and as he heard the words, he saw the large bare patch of ground, where the snow had melted and the grass beneath was dry and singed.
"Here," he said. Alyss joined him, dropping to one knee and running her fingers over the dry, brittle grass. She let go a small grunt of satisfaction.
"All right," Will told her. "I've found your scorched grass. Now what does it mean?"
"You've seen a magic lantern show?" she said. As children in the Ward at Castle Redmont, they had often seen a traveling entertainer's magic lantern show, where the shadows of cutout figures-stars, half moons, witches and their cats-were projected onto the wall of a room by a candle's light.
"I'm guessing," she said, "that your Night Warrior is the same thing in principle."
"But he was huge!" Will protested. "And he must have been thirty or forty meters from here. You'd need an awfully powerful light to manage that."
Alyss nodded. "Exactly. And a powerful light would mean an awful lot of heat-hence the scorched ground here."
"But the distance…" Will began. After all, the shows they'd Seen as children had been staged inside rooms, with the shadows barely a few meters from the light source.
"There are ways of focusing light so it becomes a beam, Will. It possible, believe me. It's very expensive and there are only a few craftsmen who can fashion the equipment for it. But it can be done. A powerful light, a focusing device and a cutout figure, and hey presto, your giant warrior appears thirty meters away."
Will was still perplexed. "On what?" he asked. "There's no wall there to project on."
"On the mist," Alyss said. "It's like a curtain it's so thick, and look how it rises from the mere in a line. That would give the flickering, pulsating effect you noticed too-as the mist eddied and moved."
It made sense, he saw. He was willing to take Alyss's word that it was technically possible. And if that were so, he was ready to pay someone back for the terror he'd experienced in the wood two nights ago.
"Someone is going to a lot of trouble to keep visitors away," Alyss said thoughtfully. "I wonder why?"
The anger was rising in Will now, along with a sense of relief-relief that there might be a logical explanation for all of this, and a living, breathing person to account for it all. At that moment, he wanted nothing more than to bring that person to account.
"Let's find him and ask him," he said, grim-faced. But Alyss was glancing at the sun and shaking her head.
"We're out of time," she said. "My escort will be back in a few minutes to pick me up. And since they are being followed, they can hardly ride around in aimless circles while I frolic in the woods."
"Fine," said Will. "You go on back. I'll keep looking for this… whoever it is."
Alyss laid a hand on his arm, and kept it there until he met her gaze. She shook her head slightly, seeing the anger, seeing the determination in his eyes.
"Not now, Will," she said. "Leave it for now and we'll come back later-together."
He said nothing and she continued. "Let's do a little more research, find out a little bit more about all this. The more we know when we go looking, the better. You know that."
Reluctantly, he nodded. His training had taught him that when you were entering enemy territory, it was best to find out all you could beforehand. Alyss saw the angry light go out of his eyes and took her hand from his arm. She smiled at him.
"Now give me a ride back to the forest edge."
"You're right," he said as he swung up astride Tug, then leaned down to help her mount behind him. "It's just that I wanted someone to pay for the way I felt the other night."
Alyss, her arms around his waist, squeezed him gently. "I don't blame you," she said. "And you'll get your chance, believe me." She was silent for a few moments as they rode back through the forest, bending low over Tug's neck from time to time to avoid the low-hanging creepers and branches that obstructed the trail. Then she spoke again.
"You know, it might be a good idea if we sent in a report to Halt and Crowley, to let them know what we've found so far. They might have some ideas about all this. We'll send it by message pigeon."
Message pigeons, Will knew, were trained by the Diplomatic Service to return to their last place of rest. Once a pigeon had flown back to its home base, it would be ready to return to the spot from which it had been released. Nobody knew how the birds managed to fix the positions in their minds, but they were invaluable for communication in the field. Alyss continued.
"I'm being watched, so I have to get back to the castle. But could you ride back, make contact with the pigeon handler, and send off a report?"
Will nodded agreement. There was certainly plenty to tell his superiors-even if, so far, there were no conclusions to be drawn.
"How will I know your man?" he asked.
"He'll know you. When he sees you, he'll make contact."
They were back at the edge of the forest now and the going was clearer. Will touched Tug with his heels and the little horse broke into a canter. As they reached the small copse of trees where he'd met Alyss, she slid quickly from the saddle, glancing anxiously along the road to the point where her escort should appear. So far, there was no sign of them and that meant there was no sign of the men following them either.
