"And another thing, Septimus," said Marcia, sounding as stern as she could manage while they watched Catchpole inexpertly wielding a large crowbar, try to lever up a dusty floorboard in the broom closet. "You are not to stay out at night on your own ever again."
"What, never?" Septimus looked up, saw the smile in Marcia's eyes and ventured, "Not even when I'm really old ... like when I'm thirty?"
"Not while you're my Apprentice you're not - oh for goodness sake, Catchpole, give me the crowbar and I'll do it - and don't think that going out with an irresponsible old ghost will be all right either, because it won't. Anyway - oof, whoever nailed this board down made a good job of it - I sincerely hope that by the time you're thirty - aha, I think it's moving - you will have an Apprentice of your own, and then it will be your turn to worry." Marcia's smile faded as she remembered. She straightened up and looked Septimus in the eye. "But I hope you never find a letter from them written five hundred years ago the way I found yours. Never."
"No. I hope not too," said Septimus quietly.
Marcia set to with the crowbar again, and a few moments later there was a loud crack as the nails finally gave up their struggle against the determined ExtraOrdinary Wizard. Septimus helped Marcia lift the board.
"I had no idea that this rose was here," said Marcia, closely inspecting the intricate rose that was carved deep into the wood. It was much worn away by hundreds of years of feet tramping over it - for the broom closet had previously been used as a cloakroom - but the delicate curves of its petals were still clearly visible.
"It was my symbol," said Septimus almost proudly. Now that he was back safe in his own Time, Septimus was beginning to enjoy thinking about his time with Marcellus Pye. "It's the old sign for a seventh son. Marcellus had it carved into his table years before I got there."
"Wicked man," said Marcia. "I'd like to tell him a thing or two."
"He was okay really," Septimus ventured.
"We'll agree to differ on that subject, Septimus," said Marcia huffily. "I am just about prepared to dig out this chest full of quackery, since even a remote chance of curing the Sickenesse is worth a try, but you will never find me agreeing that that man was 'okay really.' Never."
Septimus and Marcia knelt down and peered into the dusty void under the floor. Gingerly, Septimus put his hand into the space and the glow from his Dragon Ring found an answering shine in the depths.
"I can see it," he said, amazed. "Here it is, just like Marcellus said it would be - sub rosa. Hidden beneath the rose."
"Oh, twaddle and tripe," Marcia huffed. "Now come on, Catchpole, don't just stand there gawking, we could do with a hand to get this thing out."
It took more than the weedy Catchpole's help to lift out the chest. It needed the combined efforts of five Ordinary Wizards - without Catchpole, who suddenly felt dizzy - to drag the chest onto the spiral stairs.
At the top of the Tower Marcia, Septimus and the five Wizards heaved the chest and dragged it along the landing. The great purple door to Marcia's rooms swung open, and everyone pushed and pulled the small but amazingly heavy chest inside. Marcia stood up with a groan and rubbed her back. "Are you sure this thing isn't just full of bricks?" she said. "What could it possibly have in it to make it so heavy?"
"Gold. It's lined with really thick slabs of the stuff," said Septimus.
"What on earth for?" asked Marcia indignantly.
"Because it's the purest, most perfect metal. And Physik is all about that too, sort of trying to reach perfection with ourselves..." Septimus trailed off, noticing Marcia's exasperated expression. It was not lost on the Ordinary Wizards either, who quickly scuttled away.
Marcia sighed. She looked down at the blackened old chest with its scraped gold corners and unbroken golden bands, and she just knew that it was going to be trouble. Not to mention the fact that it was making horrible dents in her best Chinese carpet. "It's all very well, Septimus," she said somewhat grumpily, "but how on earth do you intend to open this thing?"
"Easy," said Septimus. He knelt beside the chest and took the Keye from around his neck. Marcia watched as he pressed it into its mirror image on the front of the chest, and slowly the lid silently opened.
Septimus looked inside and smiled. Everything was as he remembered, neatly laid out, clean and tidy. Lines of gleaming gold instruments lay in a tray; bottles of tinctures and mixes, remedies and fusions lay just as he had left them. And, at the bottom of the chest was what Septimus was looking for: his carefully written formula for the antidote to the Sickenesse.
"Here it is," he said, triumphantly pulling out a ragged piece of much-folded vellum. "Look." Septimus handed it to Marcia, who put her spectacles on. The hours of perusing Jillie Djinn's prediction tables and calculations had done her eyesight no good at all, and she peered at the fine brown-ink scrawl that covered the vellum. Her face brightened; at least she recognized what it was: an example of late Etheldredda/early Esmeralda variant script with the typical reverse scrawl used by the Physicians of those days.
"Right, Septimus," said Marcia briskly, glad at last to be able to take charge. "Get yourself down to the Manuscriptorium and have the Ancient Script Scribe write you an immediate translation - immediate, mind. No messing about. There's no time to lose. Off you go. Well, go on."
Septimus shook his head. "But I don't need to do that - I wrote this myself."
Marcia felt very odd. She had to go and sit down.
Some hours later, Septimus was carefully drawing up a colloid of silver with his pipette and dropping it into a large flask. Marcia, feeling rather unnecessary, sat watching her Apprentice finding his way around the old Physik Chest with an ease that amazed her.
Despite Septimus's long tangled hair, which she really must get him to do something about, and the fact that he was definitely a little taller and thinner, she found it hard to believe that he had really been away for nearly six months of his life, while only two days had passed at the Castle. And something else was different about Septimus too. He was more assured and - this was what Marcia found really strange - now he knew and believed things that she did not. That took a bit of getting used to.
"Do I add the valerian to this or add this to the valerian? What do you think?" Septimus's voice broke into Marcia's thoughts.
"You're the expert, Septimus," said Marcia, trying to get used to her new role. "But as a general rule I would say add light to dark."
"Okay." Septimus added the greenish oil to the contents of his flask. "Now, could you pass me the balance, please?" he asked. Getting into her role of lab assistant, Marcia handed Septimus a small set of gold scales complete with tiny gold weights. She watched him pick up the smallest weight with a long-nosed pair of tweezers and place it on the balance. Then, taking out a tiny, round-bowled gold spoon, Septimus measured out a fine blue powder and poured it onto the other side of the scales until the two sides were delicately balanced, and then something caught his eye. He looked at the spoon more closely and frowned.
"What's wrong?" asked Marcia.
Septimus passed her the spoon. He pointed his blue-stained finger to some marks underneath the handle.
Marcia fished out her spectacles from her pocket and peered at the scratches on the spoon. "Sep ... tim ... us," she read slowly.
"I remember writing that," said Septimus. "It was the day after I ... arrived. I wrote my name everywhere for a while. It was like writing messages forward to our own Time."
