Hildegarde was on duty at the Palace door when Gringe arrived, breathless and frazzled.

"I've come on important business on be'alf of the ExtraOrdinary," puffed Gringe. "I need to see Silas 'Eap."

"I'm afraid no one knows where he is, Mr. Gringe," said Hildegarde apologetically. "The Princess was looking for him earlier and could not find him."

" 'E'll be with the Counters, miss. Up in the attic."

Hildegarde smiled at Gringe. "Well, you are welcome to go in, Mr. Gringe, and try your luck."

"Thank you, miss." Gringe, still a little overawed by the Palace, hurried past and disappeared into the shadows of the Long Walk. Minutes later he drew back a ragged curtain hanging in a dark alcove and took a long flight of dusty stairs up to the attic. At the top Gringe pushed open the creaky door and peered in; at the far end of the long, beamed loft space, he saw the flickering light of a candle. Silas Heap was exactly where Gringe had expected - in the UnSealed room tending his Counter Colony.

The Counters were doing well, and at Gringe's approach Silas looked up, pleased to see his friend. "Look at this little fellow, Gringe. He's going to be a perfect Tunneler. I'm training him, getting him used to wriggling through things. Look at him go."

"Yeah, very nice, Silas, I'm sure. But I ain't come to watch your precious Counters."

Silas did not reply. He was down on his hands and knees, squinting into recesses under the floorboards. "Darn. He's gone. He's tunneled off."

"Yeah, well, that's the trouble with Tunnelers, Silas. Now look 'ere, I've had the ExtraOrdinary on at me and I've 'ad to leave the good-for-nothing Bridge Boy on the Gate - and Mrs. Gringe'll have my guts for garters when she finds that out, make no mistake - but we've got to put that painting back up 'ere an' you got to Seal the room again. Pronto."

"What are you going on about, Gringe? What painting? Here, boy, come on, boy, that's it ... oh, he's gone again. Darn."

"The portrait of the crazy old bird in the crown. Pointy nose and scary look in 'er eyes."

"I'm not putting that thing back here, it'll unsettle the Counters. It can go somewhere else in the attic if they don't want it downstairs."

Gringe shook his head. "It's got to go back in 'ere, Silas - back to where it was before. And you've got to Seal it in like it was before an' all. Matter of Life or Death, your boy said."

Silas looked up. Gringe had his full attention now. "Which boy?" he asked, hardly daring to hope.

"Your Apprentice boy. Septimus."

"Septimus? When did he say that?"

'' 'Bout 'alf an hour ago. He was with the ExtraOrdinary. She's got scary eyes, an' all, 'asn't she?"

In a flurry of dust, Silas leaped to his feet. "He's back - Septimus is back! Is he all right, Gringe?"

Gringe shrugged. "Looked all right to me. Bit scruffy, I suppose."

"And Jenna, is she back too?"

"I dunno, Silas, do I? No one tells me anything - except to move pictures around or get shoved in the lock-up," Gringe said grumpily.

"I must get to the Wizard Tower and see him," said Silas, gathering his dusty Ordinary Wizard robes around him and, candle held high, setting off toward the little door at the far end of the attic.

"He ain't there, Silas," said Gringe, running after him. "He's gone to the Infirmary. Got some cure for the Sickenesse or something. Silas, we gotta take care of that portrait or I'm in big trouble."

Silas ignored Gringe. He rushed off, stumbling over the uneven floor, picking his way around the broken and rotten boards. Suddenly Gringe said something Silas had never heard him say before.

"You've got to take care of that picture, Silas - please."

Silas stopped. "What did you say, Gringe?"

"You heard."

"Well, it must be serious. All right, come on, Gringe. We'll fix the picture."

It was a struggle getting Etheldredda's portrait off the wall. Silas got the impression that the picture had a mind of its own and did not want to be moved. Eventually a vicious tug from Gringe pulled the painting, along with a great lump of plaster and the picture nail, away from the wall and sent Gringe flying with it. Then, with a fair amount of what Sarah Heap called "language," Silas and Gringe began the awkward task of manhandling the disapproving portrait up the attic stairs.

"You'd think this thing 'ad arms," muttered Gringe after squeezing around a particularly tight corner. "Feels like it's 'olding on to the banisters."

"Ouch!" gasped Silas suddenly. "Stop kicking my shins, Gringe. That hurt."

"Weren't me, Silas. In fact - ouch - you can stop kicking my ankles."

"Don't be silly, Gringe. I've got better things to do than kick your stubby little ankles. Hey! That was my knee. You try that one more time, Gringe, and I'll - "

"You'll what, Silas 'Eap? Huh, huh?"

Both Silas and Gringe were battered and bruised and very near coming to blows by the time they reached the landing outside the attic door. They leaned the portrait against the wall and glared at each other, while the portrait glared at them.

"It's 'er, isn't it?" muttered Gringe after a while. "I dunno how she's done it, but it's been 'er that's been kicking us."

"Wouldn't be surprised," said Silas, accepting Gringe's peace offering. "Come on, Gringe, let's have a rest, we'll do this later. Fancy a game of Counter-Feet?"

"Deluxe version?" asked Gringe.

"Deluxe version," agreed Silas.

"And no mini-crocodiles?"

"No mini-crocodiles."

On the floor below, Jenna and Sir Hereward were listening to the bumps and thumps above their heads. Jenna had returned to the Palace and, unable to find Silas or Sarah, had gone to see Sir Hereward. He was at his usual post, half hidden in the shadows, leaning against a long tapestry that hung down beside the doors.

"Good morning, fair Princess. The Palace rats do grow ever bolder, I declare," said the knight, pointing his broken sword up to the ceiling, where, immediately above them, Silas had got his foot stuck between two rotten floorboards.

"Good morning, Sir Hereward," said Jenna, who had become used to noises in the attic ever since Silas had started cultivating his Counter Colony. "They sound like two-legged rats with boots on to me."

Sir Hereward looked at Jenna as if searching for an answer to something that was bothering him. "You are safely returned after your absence?" he asked. "For as I recall you were not here last night, nor the night before - two long nights indeed, for none knew where to find you. Tis good to see you, and with a little orange rug as a keepsake from your travels. How very charming."

"It's a cat, Sir Hereward," said Jenna, holding Ullr up to show the knight.

Sir Hereward peered at the scrap of orange fur. Ullr stared vacantly at the ghost, seeing only a Time five hundred years ago. " 'Tis a poor kind of cat," observed the knight.

"I know," said Jenna. "It's like he's not here anymore."

"Perchance your cat has the Sickenesse," said Sir Here-ward.

Jenna shook her head. "I think he's missing someone," she said. "Just like I am."

"Ah, you are strangely melancholy this morning, Princess, but here is something to raise your spirits. What is the difference between an elephant and a tangerine?"

"One's big and gray and has a trunk, and the other is small and orange."

"Oh." Sir Hereward looked crestfallen.

"Just joking. I don't know, what is the difference between an elephant and a tangerine?"

"Well, I won't send you out to do my shopping then. Hur hur."

"Ho, ho. Sir Hereward ... you know where I went away to, don't you?"

The knight seemed unwilling to answer. He poked his sword at his foot and fiddled with a loose plate of armor. "Only you can know that, Princess. Where, pray tell me?"

"I was here, Sir Hereward. And so were you."

"Ah."

"I was here five hundred years ago."

Sir Hereward, who as an old ghost was on the transparent side already, nearly faded away. But he recovered himself enough to say, "And you are back. Safe. And only two days gone. It is a wonder, Princess Jenna, and it is a burden lifted from my old shoulders. Ever since you told me your name was Jenna, I have worried that one day you would disappear and never be seen again."

"You never said."

"I thought that it was not something you would wish to know, Princess. It is best not to know what the future holds for us." Jenna thought of Marcellus Pye knowing that he had at least five hundred cold, dark years to spend alone in the Old Way, and she nodded.

"I have so many questions to ask you about what happened in the past, Sir Hereward."

"One at a time, Princess. I'm an old ghost now, and my memory tires easily."

"Just one today then: Did Hugo get home safely?"

Sir Hereward looked puzzled. "Hugo?" he asked.

"You remember Hugo," said Jenna. "He was with us. Well, with Septimus really. Wore a Palace Servant's uniform that was far too big for him."

Sir Hereward smiled. "Ah yes, I remember Hugo. And very pleased his mother was to see him too."

"I'm glad. Hugo was sweet."

"Yes. He became a wonderful Physician later, due to young Septimus Heap, he always said. But I shall cause you to tarry no longer. You will be wanting to go to your Chamber and rest."

Jenna shook her head, the memory of the little Princesses' crying behind the wainscoting was still fresh. "No, not just yet, thank you, Sir Hereward. I am going to sit by the river."

The autumn sun had warmed the old planks of the landing stage, and Jenna - comfortably upwind from Billy Pot's piles of dragon dung - was sitting with Ullr on her lap, dangling her feet into the surprisingly warm water of the sluggish river. Beside her was a blue and white saucer full of mashed corn, and nibbling at the corn was a small, naked duckling. As Jenna watched the corn steadily disappear into the duckling, her eyes grew heavy, and the blankets and cushion that she had brought down from Sarah Heap's living room seemed irresistible.

Which is why, when the Chief Customs Officer's launch drew up alongside the Palace landing stage, Alice Nettles and Alther Mella found a steadily breathing pile of crocheted blankets with an orange cat with a black-tipped tail and a small, stubbly duckling asleep on top of it.

"It's Jenna!" Alice gasped, recognizing Jenna's dark hair and the golden circlet. "How did she get here?"

"Are you sure?" asked the ghost, hardly daring to believe it. Alther and Alice had come to the Palace to break the terrible news of Jenna's and Nicko's disappearance to their parents. Alther had been ready to fly off alone, but Alice had insisted on going with him, and so Alther had followed the Customs Launch on its long journey upriver, all the while dreading what he was going to have to say.

"See for yourself." Alice smiled. "She's fast asleep."

Gently, Alther blew the covers back from Jenna's face and saw for himself. Jenna stirred at the ghost's warm touch but slept on, exhausted.

"Best to leave her sleeping," said Alice. "It's a warm afternoon, and she'll come to no harm."

"Funny ducklings they have around here," said Alther as he and Alice wandered across the sunlit lawns toward the Palace. "Must be a fancy new breed, I suppose."
