The smoke was finally beginning to clear; it seemed to be draining, rather than rising, from the court. Mr. Threader approached. “Did anything strike you, Dr. Waterhouse?”

“Not very hard.” For the first time it occurred to him to brush himself off. Wood-shards and raccoon-tufts showered from the folds of his clothing. His finger caught the edge of a coin, which had been made rough as a saw-blade by the violence of its recent career, and this fluttered to the ground and hit with a tinny slap. Daniel bent to examine it. It was not a coin at all. It was a miniature gear. He picked it up. All round him, Mr. Threader’s assistants were in similar postures, snatching guineas off the ashlars like a crew of gleaners. The driver of the baggage-cart was face down, moaning like a drunk as he was tended to by Henry Arlanc and a woman, possibly Arlanc’s wife. Someone had had the presence of mind to draw the other baggage-cart across the entrance of Crane Court so that the Marching Watch-when and if they arrived-would not simply march in watching for stray coins.

“At the risk of being one of those bores who will only venture to state facts after they have become perfectly obvious to all,” said Mr. Threader, “I guess that my baggage-cart has just been Blown Up.”

Daniel flipped the gear over in his palm several times, then put it in his pocket. “Without a doubt, your hypothesis passes the test that we call, Ockham’s Razor.”

Mr. Threader was strangely merry. For that matter, even Daniel, who had been in a sour mood all day from fasting, was feeling a bit giddy. He saw Henry Arlanc approaching, wiping traces of blood from his hands, his face blackened. “Mr. Arlanc, if you are all right, would you be so good as to fetch a broom, and sweep my things in-doors?”

This actually produced a guffaw from Mr. Threader. “Dr. Waterhouse! If I may speak frankly, I had been concerned that your coonskins would leave you open to ridicule from London’s a la mode. But in the end, the Garment in Question was not even suffered to pass the city gates.”

“It must have been done by someone very young,” Daniel guessed.

“Why do you suppose so, sir?”

“I have never seen you happier, Mr. Threader! Only a fellow who had lived through very little would imagine that a gentleman of your age and experience would find this sort of thing impressive.”

This hammered a bung into Mr. Threader’s barrel of chuckles, and straightened him right up for several moments. In time he worked his way back to merry, but only after perilous detours through confused, astonished, and outraged. “I was about to make a similar remark directed at you!” He was less shocked by the explosion than by Daniel’s imputation that it had anything to do with him. Another cycle of bewilderment and stifled anger swirled round his face. Daniel observed with some fascination; Mr. Threader had facial features after all, plenty of them.

In the end, all Mr. Threader could do was laugh. “I was going to express my outrage, Dr. Waterhouse, that you imagined this had anything to do with me; but I bated. I cannot throw stones, since I have been guilty, mutatis mutandis, of the identical sin.”

“You thought it was for me!? But no one knew I was coming,” Daniel said. But he said it weakly, for he had just remembered the pirates in Cape Cod Bay, and how Edward Teach, literally smouldering on the poop deck of Queen Anne’s Revenge, had asked for him by name.

“No one, save the entire crew of the ship that put you ashore at Plymouth-for she must have reached London by now.”

“But no one knew how I was coming to London.”

“No one, save the Court of Directors, and most of the Investors, of the Proprietors of the Engine for Raising Water by Fire! Not to mention your Backer.” Mr. Threader then got a bright look on his face and said, “Perhaps they were not trying to affright you, but simply to kill you!”

“Or you,” Daniel returned.

“Are you a wagering man, Dr. Waterhouse?”

“I was brought up to loathe it. But my return to London is proof that I am a fallen man.”

“Ten guineas.”

“On the identity of the intended victim?”

“Just so. What say you, Dr. Waterhouse?”

“As my life is already staked, ’twere false ?conomy to quibble over ten guineas. Done.”

But what should be the reason that such a good man should be all his days so much in the dark?

-JOHN BUNYAN, The Pilgrim’s Progress

DANIEL’S FIRST FORTNIGHT at the Royal Society was not equal, in excitement or glamour, to that fiery Spectacle that had heralded his arrival. In the minutes after the blast, excitement born of fear had made him feel half a century younger. But the next morning, he woke in his little guest-garret to discover that the thrill had vanished as quickly as the smoke of the blast; while the fear persisted as stubbornly as the carbon-black scorches it had sprayed on the pavement. Aches and pains had appeared in every part of him, as if all the shocks and insults he had suffered since Enoch Root had walked into his Institute some four months ago, had not been registered at once by his body, but had been marked down in a credit-ledger which had now come due, all at once, and with usurous interest.

Much more debilitating was a melancholy that settled over his spirit, and took away his desire to eat, to get out of bed, or even to read. He only stirred at odd intervals when the melancholy condensed into a raw, beastly fear that set his heart thumping and caused all the blood to drop out of his head. One morning before dawn he found himself crouching before his tiny window, twitching a linen curtain, peering out at a wagon that had trundled into Crane Court to deliver some sea-coal to a neighboring house, wondering whether the collier and his boys might be disguised murderers.

His own clear awareness that he had gone half mad did nothing to lessen the physical power of his fear, which moved his body with irresistible power, as a sea heaves a swimmer. He got no rest during the two weeks he spent in that garret, despite staying in bed most of the while, and realized only one gain: namely, he arrived at a better understanding of the mentality of Sir Isaac Newton. But that hardly seemed like a reward. It was almost as if he had suffered a stroke, or a blow to the head, that had stolen away his faculty of thinking about the future. He was quite certain that his story had come to an end, that his sudden journey across the Atlantic was a flash in the pan, which had quite failed to ignite the powder in the barrel, and that Princess Caroline would purse her lips, shake her head, and write it all off as a failed investment and a Bad Idea. Really he was no better off during that time than he had been tied to Hooke’s chair at Bedlam being cut for the stone. The pain was not as intense, but the mental state was much the same: trapped in the here and now like a dog, and not part of any coherent Story.

He got better on Saint Valentine’s Day. The agent that brought about this miraculous cure was as obscure as the cause of the disease itself. It certainly did not originate from the College of Physicians, for Daniel had used what energies he had to keep the doctors and their lancets at bay. It seemed to issue, rather, from a part of town that had not existed when Daniel had been a young man: a place, just up the road from Bedlam, called Grub Street.

Daniel’s medicine, in other words, was Newspapers. Mrs. Arlanc (the wife of Henry, an English Dissenter, and the housekeeper of Crane Court) had been faithfully bringing up food, drink, and new-papers. She had told visitors that Dr. Waterhouse was deathly ill, and physicians that he was doing much better now, and thereby stopped all of them from crossing his threshold. At Daniel’s request, she refrained from bringing him his mail.
