A half-rat, half-human face was eerily illuminated in the yellow glow of Septimus's Dragon Ring.
Jenna suppressed a scream.
The body of Ephaniah Grebe was propped up in the far corner of the tree house, exactly where the Thing had left him for the more agile frame of the Toll-Man. Ephaniah's head lolled forward like a broken doll's, and his white robes looked like a pile of dirty sheets waiting to be washed. As soon as Jenna saw him, she knew he was UnInHabited - the difference between Ephaniah now and the last time she had seen him was obvious. This was Ephaniah - she felt no revulsion, no sense of overwhelming rat-ness and none of the feeling of pity and hopelessness that the InHabited Ephaniah had filled her with. And, she saw, his left little finger was ring-free. She rushed over to the rat-man and touched his hand. It felt cold.
"Oh, Sep, can you Hear...anything?" she whispered.
Septimus knew what Jenna was asking. He Listened for the Sound of Human Heartbeat. "I don't think so," he said, then he saw Jenna's expression and added hurriedly, "but I think that's because there's so much rat there. All I can Hear is Beetle's, which is slow and steady, and yours, which is really loud."
"Oh," said Jenna, surprised. "Sorry. What about yours?"
"You can never Hear your own," said Septimus. He thought for a moment. "We'll do it the old way," he said.
Septimus kneeled beside Ephaniah and took his emergency Physik tin from his pocket. The tin was crammed full of things that Jenna had no idea why he could possibly want. From it he selected a small, round mirror and held it close to Ephaniah's slightly open mouth from which two long, narrow teeth protruded. A light misting appeared on the glass. "Well, he's still breathing," said Septimus.
"Oh, Sep, that's wonderful." Gently, Jenna stroked the rat-man's soft nose, intrigued at the way the human features merged so well with the rat fur. As she stroked the fur, Ephaniah's eyes fluttered open for a brief moment. "He saw me," whispered Jenna. "His eyes smiled. He's okay. I know he is."
"It'll take a while to be sure about that," said Septimus, who knew enough Physik to know that nothing is certain. "But at least he's got a chance."
The tree house was surprisingly comfortable, if a little strange. It was completely lined with a coarse reddish fur, and once the door flap was closed no light entered at all. In the opposite corner from where Ephaniah lay, his head resting on a pillow that Jenna had made from the Toll-Man's blankets, there was a small stove set on a thick piece of slate. After several attempts to light it with Beetle's tinderbox, Jenna finally coaxed a large yellow flame from the big round burner. Septimus took the battered old pan that hung from a hook above the stove, climbed down the tree and scooped up some snow. With his pan piled high with snow, poised to climb back to safety, he stopped for a moment and listened. A bloodchilling ululating howl - the same one that they had heard the night before - pierced the air and Septimus felt the ground tremble beneath his feet.
Startled, he looked up and saw a long, dark shape moving along the path around the chasm. It was coming toward him - fast. With a sudden certainty Septimus knew what it was - and what had gone past them earlier hidden in the fog. He did not waste a moment; he dropped the pan and shot back up the rope ladder. As he threw himself into the tree house, the whole tree began to shake.
"Earthquake!" cried Jenna.
Septimus shook his head. "No," he said. "Foryx!"
Terrified and fascinated at the same time, Jenna peered out of the door flap. A phalanx of Foryx was hurtling through the snow, so fast that Jenna's only impression was a long, red streak of galloping fur and tusks as the Foryx thundered past on the path below the tree house.
"They're real!" said Jenna.
"A bit too real," said Septimus.
A few minutes later, pointing to the walls of the tree house, Jenna said, "You know what fur this is, don't you?"
"Foryx," said Septimus with a grimace.
Jenna smiled. "Which means, if you think about it, that we are already in a House of Foryx."
"Well, I wish Nik were here," said Septimus glumly.
"I know. So do I."
Jenna made Septimus go back for some snow. "We'll hear them if they're coming back," she said when Septimus had objected. "And make sure you get the snow from a clean patch. We don't want Foryx dribble for supper."
Septimus broke the record time for snow collection. While Jenna boiled up some witches' brew, Septimus sat next to Beetle and looked through his Physik tin with a feeling of anticipation. At last he was getting a chance to try out the Physik he had learned on a real patient. Beside him his unwitting patient dozed peacefully on the floor of the tree house, pale but breathing steadily. The thick yellow flame of the stove filled the tree house with a comforting glow and the warmth began to bring out the pungent smell of the Foryx skins. Septimus decided it was time Beetle woke up and drank some witches' brew. He took out a small phial labeled Sal Volatile and was about to waft it under his new patient's nose when Beetle suddenly opened his eyes. Foryx skin reek was as effective as any phial of Sal Volatile.
Beetle had a nasty gash behind his right ear and now that he was warming up it was beginning to throb painfully. "Ouch!" he protested as Septimus cleaned up the dried blood with some sphagnum moss dipped in antiseptic.
Jenna looked up as she was dropping three squares of toffee into the boiling water. "You're turning him purple, Sep." She laughed.
"Purple?" said Beetle. "Wotcha doing, Sep?"
"It's Gentian Violet," Septimus explained. "It will stop the cut from getting infected. But we need to keep the edges together. Wait, I've got something here." Septimus picked up a large needle.
"What's that for?" asked Beetle suspiciously.
"Oh, that? Well, when I was learning about Physik, Marcellus took me to watch a surgeon at work,"
said Septimus. "Someone came in with a deep cut and he sewed the edges together."
"He did what?" Jenna asked, wide-eyed.
"You're joking," said Beetle.
