“A different form?”
Burton sat on a leather-upholstered chair and, for the final time, told the full story.
When he finished, the Steam Man raised the letter again.
“Hmm,” he said. “This pyramid construction appears to have the elements of a battery. You say there were other structures of alternating layers in the temple?”
“Yes.”
“And a great deal of quartz?”
“Along with other crystals and gemstones, yes-an almost inconceivable amount.”
“Intriguing. My hypothesis, then, is that the entire temple was constructed to generate and store piezoelectricity.”
“Piezoelectricity?”
“A very recent discovery, Sir Richard. Or so I thought. I now learn that it was, in fact, employed in ancient times!”
“But what is it?”
“Put simply, it is electrical power generated by certain substances, crystals especially, when they are distorted by pressure.”
“Ah. And the temple-”
“Has the weight of a fractured mountain on top of it. That, Sir Richard, is a lot of power. Having it hit you in the head should have been enough to burn you to a cinder in an instant. Yet, instead, it projected you through time.”
“It passed through Herbert Spencer-or rather through the priest K'k'thyima-first.”
“It did. Or perhaps it would be more accurate to say that it passed through the seven stones of the Cambodian Eye. It seems to me that the intelligence in those stones was somehow able to control the force, and, I should think, set the coordinates for your destination in time.”
“Good,” Burton responded.
“Good, Sir Richard?”
“Yes.”
“Why?”
“Because you've confirmed my own suspicions on the matter. If we are correct, my plan has, perhaps, some small chance of succeeding.”
“You have a plan?”
“Of sorts.”
“Then I think perhaps I had better hear it.”
At four-thirty in the morning, a strong vibration shook the floor of the rooms beneath the Tower of London. It rapidly increased in intensity and a loud rumbling shocked the secret institution's staff out of their beds.
People, wrapped in dressing gowns, ran into the main hallway.
“Earthquake!” someone shouted.
Damien Burke, in a long nightshirt, nightcap, and slippers, yelled: “Up the stairs! Now! Everybody out!”
A guard unlocked the entrance door and the staff quickly filed out.
The floor cracked. A siren started to wail.
Gregory Hare, also in his sleeping clothes, pointed to a lone figure at the other end of the hallway-a woman, white-haired and fully dressed.
“Mr. Burke!” he called.
Burke followed his companion's pointing finger and saw the woman.
“Countess Sabina!” he shouted. “You must leave at once!”
The rumbling grew into a roar.
“I think not!” she mouthed, her voice lost in the din.
The floor in the middle of the hallway bulged and heaved. Dust erupted and filled the air as a spinning metal cone emerged from the ground and expanded upward. The deafening commotion caused Burke and Hare to press their hands to their ears. They blinked against the eddying dust and squinted through watering eyes at the massive drill as it thundered out of the floor and its tip bit into the ceiling. Shredded plaster and masonry exploded outward.
“Mr. Burke! Mr. Burke!” Hare bellowed, but the other man could hear nothing but the cacophonous machine.
The drill buried itself deeper and deeper into the roof, and, as it did so, the main body of the tunnelling machine rose into view. Steam belched out of holes in its sides until the atmosphere of the hallway was so thick that nothing could be seen, though electric wall lamps continued to glow.
Burke groped for Hare's arm, clutched it, put his mouth against the other man's ear, and yelled: “Find your way to the armoury. Bring weapons!”
He felt his colleague move away.
The noise suddenly died. There was a moment of absolute silence, then the rattle of debris as it continued to fall from the ceiling.
A clang and a creak.
Thumping footsteps.
A repetitive wheezing.
The hiss of escaping vapours.
Something moved in the murk-a shadow-then a man stepped out of the cloud. Though the bottom half of his face was concealed by a scarf and the eyes were behind leather-rimmed goggles, Burke recognised Sir Richard Francis Burton.
“Captain!” he exclaimed. “Thank goodness! What's happen-”
He was cut short as Burton's fist shot up and connected with his chin. Burke folded to the floor.
“My apologies, old thing,” the king's agent murmured.
He moved back to the Worm. Two figures-Isambard Kingdom Brunel and Maneesh Krishnamurthy-were standing beside it.
“This way!” he snapped.
He led them toward the far end of the hall but stopped short when someone stepped into his path. He drew back his arm, his fingers bunched into a fist.
“No!” came a female voice. “It's me!”
“Countess! What are you doing here?”
“They've been using me in their campaign against the Prussians, Sir Richard. I can stand it no longer. Besides, I foresaw that you would come. There is a role for me to play. I must accompany you.”
Burton hesitated, then said, “Get into the vehicle, Countess. We'll join you in a minute.”
As she moved away, the explorer strode forward and kicked open the door to the security section. He entered, Krishnamurthy followed, and Brunel squeezed through after them.
“This one,” Burton said, indicating the entrance to Cell 4.
He moved aside as the Steam Man's multiple arms raised cutting tools and applied them to the metal portal. Moments later, Brunel pulled the door from its frame and threw it aside.
“John!” Burton called.
“Dick, what's happening?”
“We're breaking you out of here! Explanations later! Come!”
Speke, still in his shirt and trousers, groped his way forward.
“This way, Mr. Speke,” Krishnamurthy said, grabbing the prisoner's arm.
They hurried back out into the main hall.
A pistol was pressed into the side of Krishnamurthy's head.
“May I ask what you think you're doing?” Gregory Hare asked.
Burton wheeled to face Palmerston's man and cried out: “Hare, it's me! Burton!”
“What's happening here, Captain?”
“I have to take Speke! Hare, trust me, man! The future depends on this!”
