cork. I pulled out the stopper, then recoiled in horror. Inside was a chunky, dark brown cream that looked like the back of a babyâs diaper. It smelled like it, too.
âSpread a layer over the rash,â Master Benedict said quietly. âThick enough to cover it, but no thicker.â
I shuddered as I slid my fingers into the slime, praying it wasnât what it felt like. Then I smeared a handful of it over Lady Lucyâs back. To my surprise, not only did she not complain about the smell, she sagged visibly in relief as the goo slid over her skin.
âMuch better,â she sighed. âThank you, Mr. Blackthorn.â
âWe shall return tomorrow, madam,â he shouted, and the chambermaid showed us out.
I put the apothecary jar back in the satchel. As I did, I saw a woollen rag inside, folded at the bottom. I pulled it out on the street, trying to wipe away as much of the foul brown gunk from my fingers as I could.
âSo?â Master Benedict said. âWhat did you learn from that?â
I answered without thinking. âAlways bring cotton to stuff your nose.â
Suddenly, I realized how that sounded. I cringed,expecting Master Benedict to beat me for insolence, like the masters at Cripplegate would have.
Instead, he blinked at me. Then he threw his head back and laughed, a warm, rich sound. It was the first time I remembered thinking Iâd be all right.
âIndeed,â Master Benedict had said. âWell, if you think that was bad, wait until you see what Iâll teach you tomorrow.â He chuckled. âCome then, Christopher. Letâs go home.â
â¢Â  â¢Â  â¢
He did teach me more that next day, and every day after that. When Iâd imagined what being an apothecary would be like, Iâd thought working in the store was where Iâd end up. But the workshop in the back became my true home. Here, Master Benedict showed me how to mix an electuary of marshmallow root and honey to soothe the throat; how to grind willow bark and infuse it into a tea that lessened pain; how to combine sixty-four ingredients over four months to make the Venice treacle, an antidote for snake venom. He taught me his own secret recipes as well, and the codes to decipher them. In this room I found my future, making miracles that came from Godâs own creation.
Some days, anyway. Today all I got was some grain, a bucket, and a poop scraper.
With my master and Stubb talking in the next room, I grabbed what I needed and left. The door opposite the giant oven led to the upper floors, with steep stairs so old, the lightest step made them squeal like a frightened donkey. On the second floor was the kitchen, small but functional, and the pantry, which kept the occasional loaf of bread or wheel of cheese, some smoked fish, and a cask or two of ale. The rest of the rooms were stuffed with supplies for the workshop.
Part of the third floor was kept for storage, too, but for Master Benedictâs other passion: books. The only thing that compared with my masterâs obsession with discovering new recipes was his obsession with discovering new books. He passed that on to me, too. Besides our daily lessons, Master Benedict expected me to study on my own, not just recipes and how raw materials reacted, but from his endlessly growing collection of tomes. From these, I learned philosophy, history, theology, languages, the natural sciences, and whatever else sparked my masterâs imagination during his weekly trips to see his friend Isaac the bookseller.
A landing at the top of the stairs swung around to Master Benedictâsprivate rooms. More books lined the walls, making the passage so slight, you had to squeeze against the railing to get to the door. Opposite my masterâs quarters, a ladder led up to a hatch in the ceiling. I unbolted it and climbed into the evening chill.
The roof of our home was flat. I liked coming up here on hot summer nights, where
