Daniel has studied a document, written in Hooke’s hand, asserting that a patient (who happened to be one Daniel Waterhouse, but that is neither here nor there) died, and was brought back to life by a coction brewed up by an Alchemist. Hooke set down the receipt as best as he could from memory. Later Isaac went through and studied this, as only Isaac could study a thing, and made any number of annotations to it, all in the mythology-ridden argot and the queer symbology of the Esoteric Brotherhood. Daniel knows more than he’d like to of such things, from having spent so much of his young life around such people, and he’s had a few days to go over Hooke’s receipt and Newton’s commentary and puzzle out what they mean. Isaac has made several attempts in recent weeks to carry out all of the steps in the procedure save the last, and so all of the necessary crucibles, retorts, &c. were lying out in plain sight on his laboratory-table when Daniel began work a couple of days ago, and all of the ingredients were there, too. All, that is, except for the last and most crucial.
