In the end he decided to go there, not because he could see any clear reason why, but because he could see no reason why not, and because it was likely to be more interesting than staying at Crane Court. The endless carriage-ride gave him plenty of time to make up his mind that he had decided wrong. But by then it was too late. He reached Orney’s ship-yard around midday. From the point on Lavender Lane where he disembarked from the hackney-carriage, he enjoyed an Olympian prospect over the entire ship-yard.

There was no wind at all today. A silent tide of translucent white smoke had seeped into the maze of stock-piles down on the bank, turning them into blocky islands. These had been little affected by the fire. Daniel’s eyes sought out the pallet where had been piled the Natural Philosophy stuff from Crane Court. Other than a few scorch-marks where cinders had showered down upon the tarpaulin, there appeared to be no damage.

Having satisfied himself as to that, he raised his eyes to the parallel ways where the Tsar’s three ships had been a-building.

The fire had started in the middle of the three hulls. As far as Daniel could make out, no attempt had been made to save this one. But expanses of sail-cloth had been drenched in the river and flung over the unfinished hulls to either side. The cloth looked very much the worse for wear-no one would ever make sails of it-but for the most part it had steamed, not smoked, in the heat of the flames. From footprints in the bankside mud and other such evidence, Daniel could infer that bucket-brigades had been formed to wet down the sail-cloth and perhaps to attack the central fire. A hue and cry must have gone up; Orney and many of his workers must have rushed to the yard. But not soon enough to save the middle ship. The fire must have worked in the belly of that hull for some time before it had been noticed. The hull-planks on both sides were charred through, and it was obvious that the keel had been damaged. It would be rated a total loss by Mr. Orney’s insurer.

This much Daniel could see from a high vantage point at the top of the stairs. Swirling heat-waves still roiled out of the destroyed hull. Through them he could see a weirdly distorted image of men on small boats rowing to and fro, peering at the disaster in something of the same spirit as other men had watched the bear-baiting.

Daniel found a stairway and descended from the lane to the yard. The smoke that lingered in the lanes among the stock-piles smelled like the aftermath of any house-fire, which was to be expected. But mixed with it, Daniel was surprised to nose out a sharp nostril-stinging fragrance that did not belong there: a chymical fume. Daniel had most recently smelled it in Crane Court, the night of his arrival, just after the Infernal Device had gone off. Before that, he had smelled it many other times in his life; but the first time had been forty years ago at a Royal Society meeting. The guest of honor: Enoch Root. The topic: a new Element called Phosphorus. Light-bearer. A substance with two remarkable properties: it glowed in the dark, and it liked to burn. He suffered a pang of incipient guilt, thinking that perhaps this was all a terrible mishap, laid to him; perhaps there had been a sample of phosphorus in among the goods from Crane Court, which had somehow caught fire, and caused the conflagration, and Kikin had called him out here only to prosecute him. This was extremely unlikely-a fair sample of the stupid terrors that continued to bedevil him from time to time. He went and inspected his pallet, and found that nothing of the sort had happened.

Daniel found Orney and Kikin in one of the surviving hulls. This was still draped in sopping sail-cloth, presumably in case the fire in the middle hull should flare up again. Orney and Kikin roamed up and down the length of the hull on a strip of temporary decking-a sort of scaffold. Daniel reckoned it had been put there so that the workers could gain access to the upper parts of the ribs, but in present circumstances it made a suitable command and observation post for the proprietor and his customer.

They took in the curious spectacle of Daniel ascending a ladder, then-since he had survived it-greeted him. Orney was smiling in the way that bereaved persons oft did at funerals. Kikin-whatever emotions he might have felt earlier in the day-was sober, avid, acute, interested in everything. “You have come,” he said more than once, as if this were a significant finding.

Norman Orney mopped his cindery visage with a corner of wet canvas. Seeing this, a boy stepped in with a bucket of beer and offered Orney a ladle-full. “God bless you, lad,” said Orney, accepting it. He quaffed half a pint in a few impressive swallows.

“It started in the wee hours, then?” Daniel hazarded.

“Two of the clock, Brother Daniel.”

“It burned for a long while, then, before anyone noticed.”

“Oh, no, Brother Daniel. In that, you are quite off the mark. I employ a night-watchman, for these banks are infested with mudlarks.”

“Sometimes they fall asleep.”

“Thank you for supplying me with that intelligence, Brother Daniel; as ever, you are keen to point out any mismanagement or incompetence. Know then that my watchman has two dogs. Both began to bark shortly after two of the clock. The watchman smelled a pungent fume, and observed smoke from yonder hull. He raised the alarm. I was here a quarter of an hour later. The fire had spread with inconceivable rapidity.”

“Do you suspect arson?” Daniel asked. The thought had only just come to him; even as he was giving voice to it he was feeling the first flush of shame at his own stupidness. Orney and Kikin made polite efforts to mask their incredulity. In particular, Kikin would presume arson even if there were evidence to the contrary; for these were, after all, warships, and Russia was at war.

What must Kikin make of Daniel?

“Had you, or your watchmen, seen any strangers about the shipyard recently?”

“Other than you, Brother Daniel? Only a pair of prowlers who stole in, night before last, on a longboat. The dogs barked, the prowlers departed in haste. But they can have had nothing to do with the fire; for the ship was not on fire yesterday.”

“But is there any possibility that these prowlers might have secreted a small object in the hull-down in the bilge, say, where it might have gone unnoticed for twenty-four hours?”

Orney and Kikin were gazing at him most intently.

“The ship is-or was-large, Brother Daniel, with many places of concealment.”

“If you find clock-work in the bilge of the burnt ship, please be so good as to inform me,” Daniel said.

“Did you say clock-work, Brother Daniel?”

“It may have been damaged beyond recognition by the combustion of the phosphorus.”

“Phosphorus!?”

“Your men must inspect the bilges and any other hidden cavities in the surviving hulls every morning.”

“It shall be done, Brother Daniel!”

“You have a fire agent in the City?”

“The Hand-in-Hand Fire-Office on Snow-Hill!”

“Pray consider me at your disposal if the Hand-in

–Hand Fire-Office tries to blame this on you, Brother Norman.”

“You may have hidden virtues, Brother Daniel. Pray overlook my stubborn unwillingness to see them.”

“Pray forgive my hiding my light under a bushel, Brother Norman.”

“Indeed,” said Kikin, “there is much that is hidden in you, Dr. Waterhouse. I would see it uncovered. Would you please explain yourself?”

“The pungent reek that your watchman complained of, and that still lingers over yonder, is that of burning phosphorus, and I last smelled it on the evening of the thirty-first of January in Crane Court,” said Daniel. He went on to relate a brief account of what had happened that night.

“Most remarkable,” said Kikin, “but this ship was not exploded. It was set afire.”
