Dark Matter

Newton’s coach drew up at Mrs. Berningham’s address in Milk Street and we set her down, whereupon my master cautioned her to return to the Whit only in daylight when her safety might be better assured.

“But how did you know Berningham’s appearance?” I asked, when she had gone up to the door of her house. “A man you have never seen nor heard of before. And yet Mrs. Berningham recognised him from your description.”

And upon my asking, Newton smiled a quiet little smile so that I thought how he seemed rather pleased with himself. “‘He giveth wisdom unto the wise and knowledge to them that know understanding. He revealeth the deep and secret things: he knoweth what is in the darkness and the light dwelleth with him.’ The Book of Daniel, chapter two, verses twenty-one to twenty-two.”

I confess that I was a little piqued at Newton’s enigmatic resort to the scriptures, for it seemed to confirm in my mind that he enjoyed confounding me, which made me feel and no doubt look mighty ill-humoured, so that my master patted my knee, like a spaniel methought, although his speech was full of much warmth and good intent toward me.

“Oh come, sir, this will not do. I would know if I am to improve myself.”

“Rest assured, my dear young friend, that you who have saved my life shall know my complete confidence. The description was furnished easily enough. Whoever forged that guinea has had a prolonged acquaintance with mercury, which produces in a man all the ill effects that were described: the blackened teeth, the tremulous hands, the great thirst. I might also have mentioned the unsoundness of mind. These effects are not generally known. I only discovered them myself as a result of a great distemper with which I was afflicted during the year of 1693, when I almost lost my mind through much experimentation in my laboratory.

“All of which leads me to suppose that the lady tells us much less than she knows.”

“How is that?”

“She told us that her husband was merely passing off the bad coin as good, when the substance of the matter is that he did forge them himself. Berningham is almost certainly the man who has perfected the d’orure moulu process for making fake gold. But it may be that she still hopes to save him from the gallows, although I have always thought that hanging and marriage go very much together as a fate.”

Newton instructed his coachman to drive to the Tower and from thence back to Jermyn Street.

“I have a favour to ask of you: that Miss Barton shall be told nothing of tonight’s adventure. She is a sensitive child, prey to all sorts of imaginings, and it would greatly inconvenience me if every time I went abroad, she were to detain me with questions regarding the safety of my person. My duties on behalf of the Mint are the only matters on which I am happy for my niece to remain in complete ignorance.”

“Depend upon it, sir. I shall be the very model of discretion where that young lady is concerned.”

Newton bowed his head to me.

“But,” I said, “since I now dare to enjoy your complete confidence, sir, I would take advantage of that to remind you of a matter in which my own continuing ignorance is an affront to me. I would ask if you have had any further thoughts regarding the death of George Macey, of whose murder you bade me to remain silent. And, if you have, I would be grateful if you would share them with me, for I do confess that my own predecessor’s death still much occupies my thoughts.”

“You do well to remind me of it,” said Newton. “But I have not lacked for diligence in obtaining more information.

“Macey was, by several accounts, a most diligent man, but not an educated one, although he does seem to have made an attempt at improving himself. None of this amounted to very much, however, and it seems that Macey often had recourse to consult the mind of a man I suspect was one of Macey’s informers, a goldsmith by the name of St. Leger Scroope. Oddly it is a name that I seem to be familiar with, although I have been unable to fathom why. And since Mister Scroope was to have been out of the country until about this time, I confess I have not pursued the matter any further, and therefore your reminder is most opportune. We shall try and visit Mister Scroope tomorrow, at his place of business in the Strand. It may be that he can shed some further light on a letter written in a foreign language that was rumoured to have come into Macey’s possession, about which, according to Mister Alingham, the Tower carpenter who was a friend of his, Macey was much exercised to comprehend.”
