“Kenealy!” Hawkins yelled. “How dare you! This is an absolute outrage!”

  “I am the prosecuting lawyer, Hawkins!” Kenealy roared, his face turning purple and the veins pulsing on his forehead. “I'm well aware that you intend to countersue, but you haven't filed the case yet, and until you do, there's not a damned thing you can do to oppose my client's wishes—and his wishes, at this moment, are that Burton and Swinburne get the hell off his estate!”

  Hawkins opened his mouth to reply but was interrupted by Burton: “It's quite all right, Mr. Hawkins. We'll leave. We don't want to contribute to what is obviously already a tense situation.”

  “Yaaas,” the Claimant drawled. “Go now.”

  Without another word, Burton took Swinburne by the arm and steered him out of the room.

  “Sir Richard!” Hawkins called as the two men crossed the threshold. Burton looked back, met the lawyer's eyes, and gave a slight shake of his head.

  As they climbed the stairs to their rooms, Swinburne said: “Well, that's that. I'd say our job here is done.”

  “You really think we just met the real Sir Roger?” Burton asked.

  “Don't you?”

  “Absolutely not!”

  “Really? What on earth is there to be suspicious about?”

  “Are you serious, Algy?”

  “Yes.”

  “You don't think it odd that Sir Roger was five foot eight at most, and very slim, whereas the Claimant is pushing seven foot tall and is probably the most obese individual I've ever set eyes on?”

  “I suppose life in Australia can change a man, Richard. Anyway, there's no reason for us to stay, is there? Shall we return to London?”

  “In due course.”

  Thirty minutes later, as Burton was packing his portmanteau, Trounce knocked at his bedroom door, entered, and cried: “What the devil are you playing at? Why are you scarpering?”

  “We're not. Algy and I are going to get rooms at the Dick Whittington Inn in Alresford,” the king's agent replied. “And you? How long do you expect to stay?”

  Trounce blew out a breath. “Phew! What can I do? How does a man go about investigating ghosts? No, Captain, I'll return to the Yard this evening and we'll see what Commissioner Mayne has to say about the whole sorry business.”

  “In that case, would you do me a favour and get a message to Herbert Spencer? I need him to let us back into the house and into the pantry. One way or another, we have to find our way through that secret door. I'm convinced the diamond is beyond it and I want to get to it before the ghost does. Tell him to meet Algy and me by the lake at three in the morning.”

  Trounce shook Burton's hand. “Very well. Good luck, Captain.”

  “The bloomin’ door is open, Boss!” Herbert Spencer whispered. “But it weren't me what opened it!”

  He glanced around nervously. The mist was rolling down the slope again, creeping toward the lake, and he wasn't happy.

  The giant swans, as yet unnoticed by Kenealy and his client, were sleeping on the mirror-smooth water, their heads resting on their backs, beaks tucked under their wings.

  Spencer, Burton, and Swinburne were crouched under a crooked willow.

  “Open?” Burton hissed.

  “Yus. I checked it afore comin’ out, an’ blow me down with a feather if the back wall weren't sunk right into the floor!”

  “And what was beyond it?”

  “A tunnel.”

  “Take us there, Herbert. We must hurry!”

  Keeping their heads low, the three men ran up the slope to the back of Tichborne House. Despite the hour, lights were burning on the ground floor. They skirted the patio and followed Spencer around the corner to the left side of the building, where the door to a coal cellar stood open.

  “We'll have to go down the chute, an’ I fear you'll get your togs a bit dirty, gents.”

  “That's all right,” Swinburne whispered. “I'm an expert at this sort of thing.”

  He was referring to the time he'd spent as an apprentice to Vincent Sneed, the master chimney sweep. The poet had been worked hard and maltreated by his vicious boss, but his experience had been instrumental in Burton's subsequent exposure and defeat of the cabal of scientists who'd been planning to use the British Empire as a subject for social experimentation.

  Swinburne swung himself onto the coal chute and slid down into darkness. Burton and Spencer followed him.

  They stood, brushed themselves down, and passed through a door into a passage, which they followed past storerooms until they found themselves back at the three pantries. The rightmost one was still empty, its contents stacked in the corridor.

  “You go on back to bed, Herbert,” Burton said, keeping his voice low, his eyes fixed on the brick tunnel visible at the back of the small room. “If you don't mind, I'd like you to remain in the house for as long as possible. The Claimant and his lawyer don't know you came with us and will take you for a member of staff. That means you're perfectly placed to keep an eye on things. Any time something of interest occurs, make your way to the Alresford post office and send a message via parakeet to me at 14 Montagu Place.”

  “Right you are, Boss!” replied the philosopher. “When you get back to the Smoke, will you tell Miss Mayson that her swans are hale and hearty? She worries about them so.”

  “I will.”

  “Good luck, gents!”

  Herbert Spencer departed.

  “Come on, Algy—let's see where this leads.”

  The king's agent and his assistant passed through the pantry and entered the tunnel. It was about eight feet in height and the same in width. After a few paces, it angled to the right; then, a few steps beyond, back to the left.

  Burton shuddered. He wasn't fond of enclosed spaces, but felt somewhat encouraged when they came to a flaming brand set in a bracket on the wall. By its light, he examined the walls, floor, and ceiling.

  “All brick,” he whispered to his companion, “and not so very old. I'd put money on this having been constructed during Sir Henry's time. And look—it definitely runs out in the direction of the Crawls.”

  They moved on until they reached a point where the tunnel's brickwork gave way to plain stone blocks.

  “Granite,” Burton noted. “We're not under the house anymore. And look how this passage is level, though we know the surface above us slopes upward. It must cut straight through to a structure beneath Lady Mabella's wheat fields.”

  “Brrr! Don't mention her! I don't want to see that blasted spook again!”

  They crept forward. Burning brands were spaced regularly along the walls.

  A few minutes later, they came to a junction and had to choose whether to turn left or right.

  “We're probably below the bottom edge of the Crawls now,” Burton observed.

  He examined the floor. There was no dust or debris, no footprints, nothing to suggest that anyone had passed.

  “What do you think, Algy?”

  “When Sir Alfred took us around the Crawls, we went counterclockwise. I say we follow suit, and go right.”

  “Jolly good.”

  They turned into the right-hand passage and proceeded cautiously along it, listening out for any movement ahead.

  Swinburne placed a hand on the left wall, stopped, and pressed an ear against the stone.

  “What is it?” Burton asked.

  “The wall is warm and I can hear water gurgling on the other side of it.”

  “An underground spring. A hot one, too. I thought so. It explains the mist. Let's keep moving.”

  As they walked on, Burton measured their progress against his memory of the topography of the surface above. He knew they were following the bottom edge of the Crawls and predicted that the tunnel would turn left a few yards ahead.

  It did.

  “We're moving deeper underground now,” he observed.

  Swinburne cast a sidelong glance at his friend. Burton's jaw was set hard and the muscles at its joint were flexing spasmo
dically. The famous explorer, who'd spent so many of his younger years traversing vast open spaces, was struggling to control his claustrophobia.

  “Not so deep, really,” the poet said encouragingly. “The surface isn't far above.”

  Burton nodded and moistened his lips with his tongue, peering into the shadows.

  The sound of dripping water punctuated the silence, though they couldn't see any evidence of it. They kept moving until they came to an opening in the left wall.

  “We're about halfway along the length of the fields,” the king's agent whispered. “This looks like it'll take us into the middle.”

  They stepped into the opening and followed the passage. After a few paces, it suddenly angled leftward, taking them back in the direction of the house. They kept going, eventually reaching a right turn, and, a good few minutes after that, another.

  “Now we're going back up the fields,” said Burton, “but this time on their left border.”

  When they again reached what he estimated was the halfway mark beneath the fields above, Burton expected to find an opening in the wall to his right. There wasn't one. Instead, the passage continued straight up to the topmost border of the fields then turned left. It continued under the highest point of the Crawls then swerved ninety degrees to the right.

  “Back in the direction of the house again!” Burton murmured.

  “This is getting ridiculous,” said Swinburne.

  The tunnel led them back down to the middle point beneath the edge of the Crawls, turned right, then a few paces later, right again.

  “And now back up to the top. We're slowly spiralling inward, Algy. It makes sense. This place follows the design of a classical labyrinth.”

  “And here's us without a skein of thread!”

  “We don't need one. Labyrinths of this sort are unicursal. Their route to the centre is always unambiguous: just a spiral that folds back in on itself over and over until the middle is reached.”

  “Where the minotaur awaits.”

  “I fear so.”

  Swinburne stopped. “What? What? Not another monster, surely?”

  Burton smiled grimly. “No. The same one, I should think.”

  “Sir Roger?”

  “The Claimant.”

  “Yes, that's what I meant.”

  Burton looked at the diminutive poet speculatively. “Odd, though, how you keep referring to him as Sir Roger.”

  “Merely a slip of the tongue.”

  “Like Colonel Lushington's?”

  “No! Let's push on.”

  The echoing dripping increased as they passed along the stone corridor, which angled back and forth, ever closer to whatever lay at the centre of the structure.

  Burton stopped and whispered: “Listen!”

  “Water.”

  “No, there's something else.”

  Swinburne concentrated. “Yes, I hear it. A sort of low hum.”

  “B below middle C, Algy. I'll wager it's the diamond, singing like the Choir Stones. That's what sets the piano off—resonance!”

  They turned a corner and saw that it was much lighter ahead.

  “Careful,” Burton breathed.

  They started to walk on their toes.

  The sound of running water was loud now, and the droning musical note could be easily heard.

  Voices came to them.

  One, harsh in tone, said: “Check the walls.”

  “Edward Kenealy,” Burton whispered.

  “Yaaas, I check,” answered another.

  “The minotaur,” Swinburne hissed.

  “Hammer on each stone,” Kenealy instructed. “Don't miss an inch. There has to be a cavity concealed here somewhere.”

  The king's agent tiptoed forward with Swinburne at his heels. They came to a right-angled turn and peeked around its corner.

  Ahead, the tunnel opened onto a large tall-ceilinged square chamber. A stream of water, about two feet wide, fell vertically from a slot in the top of the right-hand wall, cascading into a channel built into the floor. It flowed, steaming, across the middle of the room and disappeared into an opening in the brickwork opposite.

  “Tears, that weep within My Lady's round,” quoted Swinburne under his breath.

  The humming of the diamond filled the space, seeming to come from everywhere at once, yet the gem was nowhere in sight.

  Something pushed through the hair at the nape of the poet's neck. A cold ring of steel touched the top of his spine.

  “Hands up!” said a voice.

  Swinburne did as he was told.

  Burton turned. “Doctor Jankyn,” he said, flatly.

  “A bullet will drill through this young man's brain if you try anything, and you wouldn't want that, what!”

  “Don't try anything, Richard,” Swinburne advised earnestly.

  They heard Kenealy call: “What's going on?”

  “A couple of uninvited guests,” Jankyn replied.

  “Bring them here!”

  “Move into the chamber, gentlemen,” the physician ordered. “Keep your hands where I can see them, please.”

  They obeyed.

  “Burton,” the Tichborne Claimant grunted as the king's agent stepped into view. “Bad man.”

  “And a trespasser,” Kenealy added. “What are you playing at, sir? I ordered you to leave the estate.”

  “I had unfinished business to attend to.”

  “As we observed. Rather stupid of you to leave the contents of the pantry piled up in the kitchen. Bogle brought it to my attention.”

  “How did you open the door?”

  “I found a lever in the left-hand room—a shelf that slides sideways and twists upward.”

  “I was a fool to miss it.”

  “You had no right to be nosing around. I should have you arrested.”

  “Arrested,” drawled the mountain of flesh standing in the centre of the chamber. The Claimant surveyed Burton with mindless eyes.

  “Try it,” the king's agent challenged.

  “Why are you meddling?” Kenealy demanded. “You're a geographer, sir! An explorer! A Livingstone! What has this affair to do with you?”

  Burton ignored the question, especially the Livingstone reference, and pointed nonchalantly at the Claimant.

  “Who—or should I ask what—is that, Kenealy?”

  “It's Sir Roger Tichborne.”

  “We both know that's not true, don't we?”

  “I insist that it's Sir Roger Tichborne.” The lawyer looked past Burton. “Is that not so, Doctor Jankyn?”

  “Absolutely!” said the physician.

  “And what do you think, Mr. Swinburne?” Kenealy asked.

  “Me? I think my arms are aching. May I lower them?”

  “Yes. Step away from him, Jankyn, but keep your pistol steady. If our guests misbehave, shoot to kill.”

  “Thank you,” Swinburne said. “And may I say, you're an absolute charmer, Mr. Kenealy.”

  “Answer my question. Is this, in your opinion, Sir Roger Tichborne?”

  Swinburne hesitated.

  “I think—”

  He raised a hand to his head and winced.

  Burton watched his assistant carefully.

  “I think—”

  The Claimant let loose a bubbling chuckle.

  “I think,” the poet groaned, “that—he is—is probably—Tichborne.”

  “Ah. There we have it.” Kenealy smiled.

  “Are you quite all right, Algy?” Burton asked.

  “Yes. No. Yes. I—my head hurts.”

  “Sir Roger,” the lawyer said, turning to the Claimant, “there is an intruder on your property. You have every right to protect your interests.”

  “Protect!” the Claimant rumbled. He lumbered forward. “Protect!”

  “Kenealy!” Burton snapped. “There is no need to—”

  The Claimant's elephantine body blocked his view of the chamber. A meaty hand shot out and grasped the lapels of Burton's jacket and shirt. Cloth ripped as
the fingers closed.

  Burton was hauled off his feet, swung around, and thrown with tremendous force clear across the room. He slammed into a wall, bounced from it, and landed in a loose-limbed heap on the floor.

  “Sir Roger!” Swinburne cried. “Don't!”

  “Heh heh!” the Claimant gurgled. He shuffled over to the prone man.

  “Perfectly legal, of course,” Kenealy observed.

  “I say! He's a jolly strong bounder, what!” Jankyn exclaimed as Burton was hoisted over the Claimant's head and thrown back across the chamber.

  “He is, Doctor,” Kenealy agreed. “Life in the colonies does that to a man, even if he was born an aristocrat.”

  Burton rolled, reached into his jacket pocket, and pulled out his pistol. As the light from the burning torches pushed the Claimant's vast shadow across him, he raised the weapon and pulled the trigger. The shot was deafening in the enclosed space and everyone flinched. A hole appeared in the cloth stretched across his assailant's belly, but no blood flowed and the bullet appeared to have little effect.

  “Baaad man,” the Claimant moaned, reaching down.

  The gun was wrenched from Burton's fingers and flung away.

  “Leave him alone!” Swinburne pleaded as Burton was gripped by the neck and jerked to his feet. “Sir Roger! Think of your family's good name! God! My head!”

  Burton launched a ferocious uppercut into his opponent's chin. His fist sank into a wobbling mass of fat. In reply, he was shaken like a rat caught in the jaws of a carnivore. His teeth rattled together. Desperately, he loosed a furious tattoo of blows into the gargantuan body, hammering it around the ribs, but he might have been punching a pillow for all the damage he did; the rib cage was buried deep beneath layers of blubber. The Claimant took the assault without so much as a groan.

  Squirming out of the creature's grasp, Burton ducked under groping hands and, like a whirlwind, dealt out roundhouse punches that should have rocked his opponent on his heels. It was useless.

  The Claimant lunged and swept his arms around Burton's shoulders. The king's agent felt them tighten and tried to slip downward, but the creature held him with the strength of a grizzly bear. Terrible agony shot through the explorer's chest and it felt as if every bone in his torso must splinter.
