"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.

"You'd better make yourself inconspicuous," she said, and Will nodded, urging Tug into the shadows under the trees. The dog followed, lying prone in the long grass.

From his position, Will could see the bend in the road a couple of hundred meters away. Now he saw the first rider in Alyss's escort rounding the bend.

"They're here," he said softly, and Alyss ran quickly to a thick clump of bushes at the edge of the trees, unfastening her short cloak and pulling the tunic over her head as she did so. She was wearing only a brief shift underneath the tunic and Will turned away hurriedly as he caught a glimpse of bare shoulders and arms. He heard rapid rustling from the bushes, then Alyss called to him.

"You can open your eyes now." She sounded vaguely amused at his embarrassment.

She had donned a long white riding habit over her tights and riding boots. The cloak, tunic and knife belt were bundled together at her feet. Will glanced along the road. The four-man escort, grouped around the mannequin tied to Alyss's horse, was almost up to them. From the shelter of the bushes, Alyss signaled to them. She turned and waved at Will, a conspiratorial grin on her face.

"See you back at the castle," she said. Then, in what was obviously a carefully rehearsed piece of confusion, the escort was alongside her. The horses milled back and forth, confusing the scene, and one of the men released a slip knot, allowing the mannequin to slide sideways off the horse. Before it hit the ground, Alyss had swung up into the saddle. Another member of the escort bent quickly to retrieve the mannequin and within a matter of seconds the group was riding on, the mannequin already half folded and out of sight.

As they moved away, Will waited, unmoving, in the trees. They were still in sight when Tug's ears twitched and the dog let out a low rumble.

"Still," Will told them both. Sure enough, two men-at-arms were rounding the bend, looking cautiously along the trail to make sure they hadn't closed up too far on the party they were following. Will sat, unmoving, as they rode past. He gave them several minutes' grace, then he rode out, heading south to find Alyss's pigeon handler.
