He dragged an armchair over to them and plonked himself into it, rubbed his short hair vigorously, then punched one hand into the other.

“Blast it!” he shouted.

“Admiral Lord Nelson,” Burton said to his valet, “would you fetch a cup for Detective Inspector Trounce, please?”

The clockwork man saluted, walked to the door, and left the room.

“I'll be blowed!” Honesty exclaimed. “Thought it was a suit of armour!”

Burton rubbed his chin thoughtfully. “I don't know, Trounce, old man,” he said. “I don't know. But you're absolutely right-the most remarkable aspect of this case is that, from the very start, the Claimant has gained supporters left, right, and centre. Judging by what I've seen so far, I'd say he radiates some sort of powerful mesmeric influence, though why it affects some and not others is quite a mystery.”

Burton remembered the people he'd seen in court rubbing their heads as if experiencing discomfort; Colonel Lushington's sudden headache when the Claimant arrived at Tichborne House; and Edwin Brundleweed's strange migraine.

It was the black diamonds, of course. Something was emanating from them. Sir Charles Babbage had said they could store and transmit the electrical fields generated by a human brain. All the evidence suggested they could influence a human brain as well.

“Your average man in the street seems under the impression that there's a conspiracy against the Claimant,” Trounce said. “He's become a hero to the working classes.”

“An aristocrat who laboured as a butcher,” Honesty commented. “They like that.”

Trounce grunted his agreement.

Admiral Lord Nelson entered with a cup in his hand.

“Pour Detective Inspector Trounce a coffee, would you?” Burton said.

“Good lord!” Honesty muttered as the clockwork man obeyed.

Strident screams and cries reached them from the street below.

“That sounds like young Swinburne,” Trounce observed.

“Arguing with a cabbie, I'll wager,” Burton agreed. “He's convinced that any cab ride, whatever the distance, costs a shilling, and he'll argue until he's blue in the face if the cabbie disagrees!”

He smiled. It had been a while since he'd seen his diminutive and highly eccentric assistant, and he'd missed him.

A few minutes later the doorbell jangled and a shout of, “Hallo, sweet angel!” floated up from the hall below. Footsteps sounded, the study door opened, and Mrs. Angell announced: “The eleven-thirty express has just pulled in at platform three, Sir Richard. Will there be much more traffic passing through the station this morning, or can I go and bathe my aching corns?”

“Send him in, Mother.” Burton chuckled. “And consider the service suspended until further notice!”

As the landlady turned to leave, Swinburne bounded past her into the room.

“Hallo! Hallo! Hallo!” he cried. “Greetings one and all! Come on! Up and at ’em! Shake a leg! Hats on heads! Let's be off! We don't want to miss it!”

Burton crossed to his friend, shook his hand, slapped his back, and said: “Hello, Algy! Off where? Miss what?”

“I'm delighted to see you too, Richard, but a little less power to your welcome, if you don't mind! Every time you pat my back, I fear bones will break. By George, you look tanned! Was South America fun?”

“Hardly that.”

“Hallo, Pouncer! Hallo, Honesty! How are London's crooks these days?”

“Busy,” Honesty answered.

“Unusually so,” added Trounce, frowning at Swinburne's use of his nickname.

“Maybe they think the steam hides their many sins! Move yourselves! Let's be off!”

“Blast it, Algy!” Burton growled. “Where to? And have you been drinking?”

“To see Kenealy and his corpulent client. They're about to perform at Speakers’ Corner! Yes, I have. Quite frankly, I'm sloshed!”

“Speakers’ Corner?” Trounce cried. “The Claimant's only just been freed from Newgate!”

“I know! But the streets are abuzz with it; he'll be lecturing the heaving throng within the hour! And I, for one, don't want the throng to heave without me!”

“I'm with you, my boy!” Trounce enthused.

Burton took a leash from the hatstand and clipped it to Fidget's collar. Jackets were buttoned, hats were placed on heads, canes were retrieved, and the four men and dog hurried out of the house into the haze of Montagu Place.

“Let's leg it down Gloucester,” Swinburne suggested. “We'll be there in five minutes.”

They strolled eastward, and, as they approached the corner, Mr. Grub's barrow came into view.

Burton touched the brim of his topper in greeting.

“Morning, Mr. Grub! How's business?”

“What's it to do with you?” came the snarled reply.

Burton halted and looked at the man in astonishment.

“I beg your pardon?”

“Oh, do yer? Well, you ain't gettin’ it, you blasted snob!”

“I say!” Swinburne gasped.

Detective Inspector Honesty turned toward the vendor and stuck out his chest. “Better watch your manners!” he said. “Respect your betters!”

“Betters, is it? Ha! You ain't no better than nuffink, an’ that's a fact!”

“Why, what on earth has got into you, Mr. Grub?” asked Burton, and Trounce added: “Come, come, dear fellow. Surely that's no way to talk!”

“Why don'tcha all clear off, hey?” Grub responded.

“Is something troubling you?” Burton enquired. “Has something happened?”

“All that's bleedin’ well ’appened is that you're a-standin’ on me patch gettin’ in the way of them honest workin’ folks what wants to buy cockles an’ whelks.”

“Well, what say I buy a bag?” Swinburne suggested. “I like my cockles with a sprinkling of vinegar, if you please.” He hiccupped.

“I don't please, an’ you can keep yer bloomin’ money, you pipsqueak! Get away from ’ere! Go on! Skedaddle, the lot o’ yer!”

The end of a tremendously long, thin leg thumped onto the road beside them as a harvestman of the order Phalangium opilio passed. The colossal arachnid-called by some a “daddy-long-legs”-was a one-man delivery vehicle. The carapace of its small oval body, which bobbed along twenty feet in the air as the eight elongated legs propelled it forward, had been carved into a bowl-shaped driver's seat, behind which a steam engine chugged. Beneath the body, a wooden crate dangled, held by netting.

The vehicle's twin funnels pumped a thick plume of steam into the air, and a tendril of the vapour curled down and rolled over the men, momentarily obscuring Mr. Grub. When he came back into view, he was holding his hand to his forehead and his face was twisted with pain.

“Why don't you all bugger off!” he mumbled as the bizarre vehicle vanished around a corner.

“I'm placing you under arrest for-” began Detective Inspector Honesty.

“No,” Burton interrupted, gripping the smaller man's upper arm. “Leave him, there's a good chap. Let's move on.”

“But-”

“Come!”

Burton guided the Yard man away, followed by Swinburne and Trounce. The latter looked back at the street vendor in puzzlement.

“By Jove! What extraordinary rudeness!” he muttered.

“And entirely out of character,” Burton observed. “Perhaps he's having trouble at home.”

“Should be arrested!” Honesty grumbled. “Insulting a police officer.”

“There are bigger fish to fry,” Burton noted.

They walked on down Gloucester Place until the northeastern corner of Hyde Park came into view. A big crowd had gathered there, comprised almost entirely of working-class men, with rolled-up shirtsleeves, suspenders, and cloth caps. A few top-hatted gents were hovering at the outer edges of the gathering. Dr. Kenealy and the Claimant could be seen near a podium. They were encircled by a number of foppishly dressed individuals-obviously Rakes-who appeared to be acting as bodyguards.

“What a crowd!” Trounce observed as they pushed their way into the mob.

“All come to goggle at the freak!” Swinburne said.
