Finally, he rounded the turn, but he'd barely lowered himself another six feet when he realised the flue was blocked. Some of the stones had collapsed in on another turn-he could feel them grinding beneath his feet-but however hard he pressed, the obstruction would not shift.
There was no way to go but back. Steeling himself, he dug his fingers in the cracks between the stones and hauled himself up. Sweating, choking, every muscle burning, he came back to the turn. It was even harder going up, and it took him the better part of half an hour to maneuver himself around it in tiny increments, dragging with his fingertips and pushing with the tips of his boots. Again he got stuck halfway around, and this time it took so long to relax his muscles, he became concerned he would suffocate before he could move.
Once he'd pulled himself up to the junction and rested his head for a moment, breathing deeply, he realised there was a current of air rising through the other flue. It gave him heart, and once again he began his slow descent.
He'd passed the worst of it, and now there were regular junctions that led down to the large stone fireplaces in every room. But though the distant sounds continued to rise through the flues, there never appeared to be any noise coming from any room he passed.
When Will estimated he'd reached the second floor, he slid down towards a fireplace, bracing himself just above the hearth to listen. When he was sure the chamber was empty, he dropped into the hearth in a cloud of soot. The room was bare apart from a cracked mirror above the mantelpiece which revealed a white-eyed black figure. Moving swiftly across the dirty floorboards to stand by the door, he waited for any who might have heard his arrival.
The house was silent. What had happened to all the noises he had heard in the chimney? he wondered. Opening the door a crack, he peered out into the corridor where a candle flickered in a holder on a small table.
Not so empty, then, he thought.
He moved quickly along the corridor, checking the rooms on either side. All were bare. Outside the last room, the boards creaked loudly, and there was a corresponding growl from the first floor, followed by heavy paws padding onto the stairs. Lightly, Will bolted up to the next floor.
Flickering light on one wall brought him to a halt just near the turn. Peering round, he saw a figure-male, although the brown hair was longmoving away from him slowly, holding a candle aloft. Below, the sound of padding paws continued up to the second floor, accompanied by another deep, penetrating growl.
Caught between the two, Will weighed his choices. Just as he had decided to draw his sword, a door at the far end of the corridor opened and light flooded out. The figure paused and communicated in a low whisper with someone within before entering the room. The door closed behind him and the light winked out.
Instantly, Will darted to the nearest door, listening briefly before opening it slowly. The room was in darkness. He slipped inside.
Closing the door, he pressed his ear against it and waited. The padding reached the top of the flight of stairs and then moved towards him. It paused outside the door and growled again, disturbingly loud in the quiet. Will held his nerve. After a second, he heard the dog move on, and listened intently until silence returned.
Will wondered if it was the same dog that had accompanied the Hunter in Alsatia. That would mean the Hunter was probably there too, he thought coldly, and perhaps even the Silver Skull.
"Who are you?"
He started at the voice, soft and dreamy with the burr of a Scottish Lowlands accent. In the dark of the room, a man sat on a chair looking out of the window, his back to Will.
Drawing his sword in an instant, Will waited for the alarm to be raised, but the man did not move. After a second, Will cautiously approached. As the moonlight broke through the window, Will saw it was a man, not one of the Enemy. He was in his forties, grey streaks in his black hair, and grey eyes that had the faraway look of a sleepwalker.
"Who are you?" Will asked.
"John Kintour," he replied. "Advisor to my queen, Mary."
"Mary is dead."
"No ... no ... I saw her this morn. So beautiful. The sun made her hair glow like fire." His voice was as insubstantial as the moonbeam breaking through the window.
Will passed his hand in front of Kintour's face, but he did not blink. "How long have you been here?"
"A day? A week? A month? A year?" He paused thoughtfully, then said, "They gave me food and drink. The most wonderful food ... The taste ... I had never experienced anything like it."
Will realised what had happened. One of the first rules during his induction as one of Walsingham's men was that he should never eat or drink anything offered by the Enemy, for it would allow them to take complete control of you. Normally it was how they lured their prey for their sport, usually simple country folk drawn to hear the music on the hilltops or in the fields at night. Kintour was clearly not being kept a prisoner in the house for sport.
"You have had a busy time here," Will said gently.
"Yes. So many questions."
"And you answered them all?"
"As best I could. Some were beyond even me. The location of the Shield-"
"The Shield? What is that?" Thinking he heard a noise outside, Will glanced towards the door. After a moment he returned his attention to Kintour.
"The Shield protects against the foul diseases released by the Silver Skull, of course," Kintour said lazily. "It allows a man to move freely among the ranks of the infected and the dead, without any mark appearing upon him. That is what the Templar Knights said."
It was as Will had thought. Without the Shield, the Skull was a blunt instrument, laying waste to vast swathes of an enemy. With it, the attacker could loot the dead, or achieve more specific aims.
"What do the Templar Knights have to do with this?" he asked.
Kintour's head rolled from side to side and he smiled faintly. "I was keeper of the records at the palace. So much to read ... so many secrets. Among the sheaves of crumbling parchment, I found many relating to the Knights Templar. At first they made little sense. It was only when I realised they were written with an obscure cipher that the truth began to emerge. The Knights encountered the Silver Skull in the Holy Lands, and knew the terrible threat it was to all Christendom. They had to act to protect all good Christian men."
"What did they do?"
"Separated the Skull from the Key and the Shield so it could not be used. They brought the latter two back here, to Scotland, and hid them well. The Skull ... I do not know what happened to that."
"The Key and the Shield were hidden at the Palace of Holyroodhouse?" Will asked.
"Hidden well. The Knights had many strong connections with Edin burgh and the surrounding area, and they were involved in advising King David when he built Holyrood Abbey in 1126. There were rumours of secret chambers beneath the abbey, and extending under the palace west of the abbey cloister. It was one of the secret locations across Europe where the Knights stored items of vast importance."
Will recalled the stories of the Knights Templar he had heard told at court, and how the religious military order had brought back many secrets and riches from the Crusades. Dee had even suggested that the disbanding of the Order and the killing of many of the Knights was down to the machinations of the Enemy. The Enemy's greatest victory, Dee had called it.
"Mary charged me with finding the location of the Key and the Shield," Kintour continued. "I searched through the old papers and spent long days and nights breaking the ciphers the Knights used. I found the Key." His brow furrowed.
"Yes, the Key was found," Will responded. "But you could not locate the Shield?"
