"So the Brigade disbanded," noted Burton, "and then you gave up the Hog in the Pound?"

"That's right. I got tired of the blooming place and all those Libertine idiots, so I sold up and bought this little boozer and-to answer your original question, sir-I named it the Tremors on account of the fact that people around here was so certain that the Technologists' power station would cause earthquakes and the like."

"You've certainly had a high old time of it!" observed Burton. "What with the Technologists, the Libertines, Edward Oxford, and Spring Heeled Jack!"

Punchinello blew out a breath and said, "He attracts crackpots!"

Robinson laughed. "You've been my customer for nigh on thirty years, Edward Toppletree, so you may well be right! Anyway, gents, I have customers to serve. Give me a shout when you're ready for a top-up."

He gave them a nod and shuffled away.

"Nice talking to you," said Punchinello. "I'm going to sit by the fire and smoke me pipe. You positive you don't want to buy Fidget, here? His nose might be the Eighth blinkin' Wonder of the World!"

"Positive!" replied Swinburne.

They bade him farewell and watched as he shuffled away with the dog at his heels.

"What do you think, Richard?" asked Swinburne quietly.

"I think," responded Burton, "that we just picked up some very useful information and I'd better speak to Detective Inspector Trounce first thing in the morning!"

BEETLE AND PANTHER

Wearing loose-fitting white cotton kurta pyjamas, a saffron-coloured turban upon his head, and with his already swarthy skin darkened with walnut oil, Sir Richard Francis Burton strode purposefully along the bank of the Limehouse Cut canal. He'd made his way there through the disreputable streets of Limehouse unmolested by the rogues who inhabited London's great melting pot. The people of this district kept themselves to themselves, only mingling when there was a shady deal to be made or a dirty deed to be done.

Without a disguise, Burton appeared barbarous enough to have probably avoided trouble. He was cautious though, and felt it best to take on the character of a foreigner. The guise of a Sikh was an obvious choice, for Sikhs possessed a reputation-undeserved, as it happened-for ferocity. This, together with his forked beard and terrible, magnetic eyes, gave him such a fearsome aspect that people quickly stepped out of his path as he swung along, and he'd arrived at the bank of the canal without having been even once approached.

Late last night, after he and Swinburne made their way home from Bat tersea, Burton had slept much more deeply than usual, not waking until nine in the morning. After bolting down a grilled kipper and a round of toast, he'd gone to Scotland Yard to present Detective Inspector Trounce with the list of Battersea Brigade members.

"By Jove!" the policeman had exclaimed. "I can't believe they missed this; though I suppose it's understandable under the circumstances. The Yard didn't have a detective branch until the early forties, and I guess the fact that the Alsop attack happened near Epping tripped them up. There was no reason to look for a connection between the girls' fathers. I'll look into this, Captain Burton. In fact, I'll go down to Battersea myself today."

An hour later, back at 14 Montagu Place, Burton found a message waiting for him from Oscar Wilde. Through the "boys' network," the youngster had arranged a meeting for him with the Beetle. The appointment was for three o'clock, and the venue was strange, to say the least.

Burton was almost there.

Along the sides of Limehouse Cut-a commercial waterway that linked the lower reaches of the River Lea with the Thames-some of the city's most active factories belched black smoke into the air and gave a meagre wage to the thousands of workers who toiled within. Many of these men, women, and children had yellow, red, green, or blue skin, permanently coloured by the industrial dyes they worked with; others were disfigured by scorch marks and blisters from hours spent next to furnaces or kilns; and all had callused hands, hard bony bodies, and the haunted look of starvation in their eyes.

Burton walked past the huge, towering premises until he came to one particular building that, unlike its neighbours, had been abandoned. Standing seven storeys high, and with nearly every window either missing, broken, or cracked, it silently loomed over the busy canal-a shell, its chimneys impotent, its entrances bricked up.

He circled it by passing through an arched passageway that gave access to Broomfield Street, crossing its barren frontage with the blocked loading bays and empty stables, then returning back along a second covered alley to the narrow docks at the side of the canal.

People saw and ignored him. That was the way of things in Limehouse.

Beside the dock, on the factory's wall, in a niche down which rusting gutter pipes ran, he found what he was looking for: iron rungs set into the brickwork.

He shifted the bag that was slung across his shoulders, moving it so that it hung against the small of his back, then began to climb, testing each foothold before putting his weight on it.

There had been a second message waiting for him at home that morning when he returned from Scotland Yard. It was from Isabel, and read: You will change your mind. We are destined for one another; I knew that the moment I saw you ten years ago. I will wait. For as long as it takes, I will wait.

He'd sat considering it for some time, absently running a forefinger along the scar on his cheek. Then he'd composed and sent a terse reply:

Do not wait. Live your life.

It was brutal, he knew, but as with an amputation, a fast and clean cut is the quickest to heal.

He continued upward until he eventually reached the top of the ladder, then heaved himself over the parapet and sat for a moment to catch his breath, looking across the flat roof at the two long skylights, the cracked panes of which had been made opaque by soot. In the centre of the roof, between the two rows of glass, eight chimneys soared high into the air. It was the third from the eastern side that interested him.

He gingerly picked his way across the debris-covered roof, avoiding the areas that sagged, until he reached the nearest skylight. He skirted around its edge then moved over to the chimney.

It had rungs affixed to it, running from the base all the way to the top. Once again, he climbed, marvelling at the view of London that unfurled beneath him. A cold breeze was blowing, making his loose attire flap, though he was kept warm by a thermal vest.

He stopped, hooked an arm around a rung, and rested. He was halfway up and could see, far away, through the dirty haze and angled columns of smoke that rose like a forest from the city, the magnificent dome of St. Paul's. A few specks flew between him and the cathedral; rotorchairs and swans, the divergent forms of air transport developed by those two powerful factions within the Technologist caste, the Engineers and the Eugenicists.

He sighed. It had come just too late for him, this new technology. If he'd had the advantage of the swans, as John Speke had during his second expedition, recent history would have been very different indeed.

He continued his ascent, giving silent thanks that he didn't suffer from a fear of heights.

Minutes later he reached the top and swung himself over to sit with one leg to either side of the chimney's lip. The breeze tugged at him but with a foot hooked through one of the rungs and his knees clamped tightly against the brickwork, he felt reasonably secure.

He noticed that another set of metal rungs descended into the darkness of the flue.
