row me over. Now I must get going."
"Not on your own," said Alther. "We'll come with you."
Sarah looked as though she was about to protest but then she changed her mind. "Thank you, Alther," she said. "I - oh my goodness!" Sarah stifled a scream. "Look..." she whispered, pointing into the darkness.
Septimus looked. At first he saw nothing and then, as he shifted his gaze, he saw them - the red eyes, moving toward them, dodging from side to side. At first glance Septimus thought it was a rat, but there was something about the way the eyes were set, both looking forward, that looked wrong for a rat's eyes. Quickly Septimus reached into his pocket, took out a pebble and sent it spinning through the darkness toward the red pinpoints. A high-pitched yelp was followed by the sound of scuffling leaves, and the eyes disappeared into the night.
"Come on, Sarah," said Alther, "let's get you down to the boatyard."
Nicko was waiting anxiously beside a rowboat tied up to the quay in Jannit Maarten's boatyard. Jannit had recently taken Nicko on as Junior Apprentice, and he now slept in a small cabin at the back of Jannit's ramshackle hut. An hour ago, Nicko had tumbled into bed, tired out after a long day helping Rupert Gringe repair the huge rudder belonging to the Port barge. He had only just fallen asleep when an insistent knocking on his window had jarred him awake - it was the Message Rat that Sarah had forwarded to him.
Quickly Nicko had found the rowboat that Jannit sometimes used to ferry people over the river; unfortunately he had woken Jannit, who even in her sleep could hear any unusual sound in the boatyard. Jannit had only just grumpily gone back to bed when she was woken again by the clinking of Sarahs bottles in her basket as she hurried through the boatyard.
Septimus helped Nicko steady the rowboat while Sarah clambered in. "You'll make sure Mum gets to the Infirmary okay, won't you, Nik?" he asked, looking doubtfully across the Moat, which was wide and deep by the boatyard, to the dim lights of the Infirmary, almost hidden under the outlying trees of the Forest some distance away. It was a dangerous walk from the ferry landing stage to the Infirmary at night.
"Of course I will." Nicko took up two long oars and waited for Sarah to get settled.
"Don't worry, I'll see Sarah to the Infirmary door," Alther said to Septimus. "I can still get rid of the odd wolverine if I have to. I'll have to whiz around by the North Gate, but I'll be there waiting for her."
"See ya later, Sep," said Nicko as he pulled away from the boatyard landing stage.
"No, you won't, Nicko," Septimus heard Sarah chide. "Septimus is going straight back to Marcia's."
As Septimus watched Alther fly toward the North Gate, a wonderful sense of freedom and exhilaration suddenly swept over him. He could go anywhere, do anything. There was no one to stop him. Of course he should go back to the WizardTower, but he was not sleepy. Septimus felt restless, as if somehow the night was unfinished. And then he realized why. Queen Etheldredda's words came back to him: "Marcellus Pye, at Snake Slipway, midnight. Be there."
Suddenly, Septimus knew why Queen Etheldredda had asked him to meet the ghost of Marcellus Pye: to give him the formula for the antidote to the Sickenesse.
It was only about half past ten. He still had time to get to Snake Slipway before midnight.
Chapter 6 The Outside Path
Septimus decided to take the Outside Path along the Castle walls, just in case Marcia had been suddenly called out on Magykal business, headache and all - it would be just his luck to bump into her. With mounting excitement, he picked his way through the boatyard, careful not to make any noise that might disturb Jannit. Soon he reached the upside-down hull of an old river barge, and squeezing behind the barge, he found what he was looking for - the steep steps that led up to the Outside Path.
The Outside Path was a narrow and crumbling ledge just a few feet above the dark water of the Moat. It had not been built as a path, but was the point at which the huge foundations of the Castle walls finished and the slightly narrower walls, which were built from smaller, more finely cut rock, began. When Septimus had been in the Young Army, many of
