With great relief, Sir Hereward had watched Marcia and Alther set off down the wide corridor, take a right turn at the end and disappear from sight.
Behind the doors of Jenna's bedroom, another, altogether more unpleasant ghost took her ear from the door, a smile playing across her thin lips. So the troublesome young Princess had run off to the Marram Marshes with the Apprentice, had she? And not done what she had promised by the sound of it. She would pay for this, and the Apprentice need not think he had gotten away with anything either.
Quickly the ghost of Queen Etheldredda crossed the floor to a small roughly made box where Jenna kept all her treasures. The ghost perused the box and then Caused the lid to silently open. Poking a long and bony finger through Jenna's possessions, Etheldredda found what she was looking for and then did something that no ghost should be able to do - she picked up the object, a small silver ball inscribed with the letters I.P. - and placed it in her pocket. Then, with a knowing smile, the ghost of Queen Etheldredda walked through the door and Passed Through the much put-upon Sir Hereward.
The ghost of Queen Cerys gave every appearance of dozing in her fireside chair, so when the ghost of Queen Etheldredda sidled in and headed straight for the potion cupboard, she was most surprised to suddenly find her way barred by a very determined descendant.
"You may not pass," Cerys told Etheldredda coldly.
"Don't be ridiculous, child. I have every right to walk the Queen's Way. And I intend to do so. Stand aside."
"I will not."
"You will!" The angry Etheldredda pushed her way through. Cerys, who gasped - not only from the shock of being Passed Through, but also from the surprisingly solid feeling of Etheldredda - recovered just in time to Cause the potion cupboard door to jam shut.
"Two may play at that game," snapped Etheldredda, Causing the door to reopen.
"But only one may win," replied Cerys, Causing the door to close.
"Indeed, child. I am glad you see sense." Etheldredda Caused the door to open.
"I intend to protect my daughter. You shall not stop me," Cerys declared angrily, and Caused the door again to slam shut. Then, before Etheldredda could retaliate, Cerys began to spin. Faster and faster she turned, like a whirlwind, revolving the air in the turret with her until, despite herself, Etheldredda was caught up in the currents and whirled around the small circular room like an autumn leaf caught up in a windy corner.
"Go!" yelled Cerys. With that, Queen Etheldredda was hurled from the room, out of the turret and across the lawns toward the river, where she landed in the middle of one of Billy Pot's careful arrangements of dragon droppings. Angrily, she picked herself out of the mess and haughtily floated toward the riverbank, where the ghostly Royal Barge awaited her.
Head held high and without a backward glance, Queen Etheldredda walked up the gangplank. As she took her place upon the dais, the ghostly barge began to move. Silently it glided away from the Palace gardens and headed for the middle of the river, where it drifted downstream, Passing Through a blockade of boats, which for some reason seemed to be on fire. Queen Etheldredda tutted to herself at the lawlessness of the Castle and comforted herself that it would not be so for much longer. She would see to that.
With a satisfied smile, Queen Etheldredda sat back to enjoy the journey. There was, thought the ghost, more than one way of getting to Keeper's Cottage.
As Queen Etheldredda was being hurled from the turret, Alther was leading Marcia down one of the many flights of back stairs that led to the Long Walk. "What exactly do you mean, Marcia - he wrote you a note nearly five hundred years ago?"
"This morning, Alther ... I opened the Sealed shelf."
"You did what?"
"You know, you showed me once how to do it. There was something there I had to see."
"Not the I, Marcellus?" Alther had become increasingly pale over the previous half hour. Now he went almost translucent.
Marcia nodded.
