Burton blew out a plume of tobacco smoke and said, “Forgive the question, Herbert-I mean no offence-but why on earth aren't you a sensation? With an intellect like yours, you should be writing books and touring universities!”

Spencer shrugged and tapped the side of his head. “When a man's knowledge ain't in order, the more of it he has, the greater is his confusion.” He looked at Admiral Lord Nelson and sighed. “I should be more like him! There's one what's got an ordered mind!”

“But no knowledge, Herbert,” Burton said. “No knowledge at all. So do you mean to say that your thinking processes are more usually in disarray?”

“Yus, just that. When I sits down an’ talks, it's all fine, but for most o’ the time, me brainbox is a right old jumble.”

“Hmm. I wonder if that has some bearing on your immunity to the Tichborne influence?”

“Richard, that doesn't make sense,” Swinburne objected. “In the main, it's the working classes who've come out in support of the Claimant, which suggests they're most affected by whatever this emanation is. If a disordered mind is immune, then the working classes have ordered minds and most of London's gentry, including yourself, don't!”

“No, Algy, that's not it at all. Let me pose a question: what would you be if you weren't a poet?”

“Dead.”

“Seriously.”

“I am serious. There's nothing else I could be. I was born a poet. I think like a poet. I act like a poet. I look like a poet. I'm a poet.”

“Accepted. By contrast, Herbert here, when we first met him, made it quite clear that he wasn't at all sure that he was cut out to be a philosopher.”

“It's no way to earn a livin’, that's for certain,” Spencer muttered.

“As for me,” Burton continued, “I've never possessed a clear idea of my function in society. I've been a soldier, a spy, a geographer, an interpreter, an explorer, an author, a surveyor, and now the king's agent, whatever the blazes that is. As for this country's gentry, I think you'll find that they mostly have a sense that life is filled with options; that, in terms of what they actually do with their time, there are few limitations.”

“Herbert used the word ‘trammelled.’ Are you suggesting that the trammelled mind is the susceptible mind?”

“Precisely.”

“Funny. I've never considered myself trammelled. Quite the opposite, in fact!”

“It's not that your mind or imagination is in any respect confined, Algy. It's simply that you've never given consideration to the notion of doing anything else. You even offered your services as my assistant because you felt the danger involved would cure your ennui and inspire greater depth in your poetry.”

“Which it has. You suspect, then, that the black diamonds somehow break down the mental structures that keep a mind channelled, which is why the working classes are suddenly feeling hard done by-they're realising that they're being cheated out of alternatives?”

“Yes. Remember the line in the poem? Vexations in the poor enables. And what about Edwin Brundleweed's story of how, the afternoon before the robbery, he suddenly and inexplicably felt dissatisfied with his lot in life?”

“But what's it all about, Richard? What's the point?”

“Judging by today's events, I'd say the point is chaos; maybe even insurgency-an assault against the very fabric of our society. I would even go so far as to say that the British Empire is under attack.”

“My hat! By a foreign power?”

“Or a budding despot. You understand now why John Speke can probably be discounted?”

Swinburne nodded. “Unless it's the Prussians. You did say he'd gone to Prussia. On the other hand, our ghost is Russian.”

Burton asked Admiral Lord Nelson to top up their cups from the coffee pot and they sat in silence for a few moments.

“Are we on the brink of a revolution?” Swinburne whispered. “Think of it! A reign of terror could descend on us just as it did on France. We might end up under the rule of an abominable tyrant like Napoleon!”

“Or we might not,” Spencer muttered. “Would it be so bad if the workin’ man-an’ woman, I might add-gained some measure of power? Don't you think it's becomin’ a matter of urgency that they do?”

“Maybe so,” Burton replied, thinking of Countess Sabina and his subsequent dream: a transition begins-a melting of one great cycle into another. “But do we really want such a change to be forced upon us by an external power? I find it inconceivable that they might be doing it for our own good!”

He flicked the stub of his cheroot into the fireplace, stood, and paced back across to the window.

“We must get to the root of this.”

His eyes scanned the road below. Two labourers were trailing along behind a gentleman, mocking him relentlessly. Despite this scene, Montagu Place was unusually quiet for the hour.

“In order to strengthen our campaign against the enemy, Algy, we must first strengthen ourselves. I've resisted it in the past, but I think it's time I mesmerised you.”

“Really?”

“Really. I want to see whether I can stop you becoming a Tichborne supporter every time the Claimant is nearby. If I can't, the only other option is for you to stay permanently drunk, and I'd rather avoid that.”

Swinburne puffed out his cheeks and expelled a breath with a pop. “Oh, it wouldn't be so bad! Besides, you've always refused to exercise your mental magnetism on me before!”

“True,” Burton affirmed. “I was concerned that your excitable disposition might react in an unpredictable manner. However, seeing as this affair is making you unpredictable anyway, my former caution seems somewhat misplaced. I shall employ a Sufi technique to fortify my own psychic defences, too. Then I have a task for you.”

“Good! What?”

“The Rake connection interests me. We've yet to identify their new leader. I want you to dig around-but keep out of mischief.”

“I'll talk to my Libertine chums. I say, though-Rakes and Tichborne-it seems a contradiction, doesn't it? If our mysterious opponent is attempting to stir up the working classes, why employ Rakes, who epitomise the idea of the insouciant aristo?”

“My thought exactly!”

Swinburne suddenly froze and looked at his friend with a puzzled expression.

“That wraith,” he said. “The one by the chaunter. You saw it?”

“Clearly!”

“For a moment, it seemed to manifest rather more solidly and took on the appearance of a tall bearded man. I swear he was wearing wire-rimmed spectacles, too. The thing of it is, I feel I've seen him somewhere before.”

“You recognised the manifestation as an actual person?”

“Yes. That wisp of steam resembled someone whose path I've crossed at some point, I'm sure of it, but for the life of me I can't recall whom. The name ‘Boyle’ or ‘Foyle’ springs to mind.”

“Keep thinking on it, Algy-it could be important.”

Spencer rubbed a hand over his bald scalp and said, “Is there anythin’ I can do to help, Boss?”

“Thank you, Herbert, there is. Your immunity and your-if you don't mind me saying so-disreputable appearance, enable you to wander through the thick of it without being molested. I'd like you to keep an eye on things at street level, see how widespread the apparitions are, and, if possible, find out where they're most numerous.”

“Right you are!”

“First, though, I'd like you to return to Miss Mayson's to make a purchase on my behalf.”

He explained further and supplied the philosopher with the requisite amount of money.

Swinburne piped up: “It's a quarter to eight, Richard. What say you we toddle on over to the Cannibal Club for a natter with Monckton Milnes? He usually has a better handle on what the Rakes are up to than I do. You can mesmerise me afterward.”

“An excellent idea. We'll take the penny-farthings. I don't fancy walking the streets at night, not while the rank and file are up in arms.”
