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.
