This entry is dated 12 January. I wanted my cellar space empty before Monday, when I start work at the library near Wilhelm-Leuschner-Platz, so I carried down the last boxes after breakfast at Backstein bakery. The cellar smelled of cold stone and wet cardboard. Behind a broken chair, I found a small brass key tied to a paper label. In blue pencil, someone had written “Dach”, roof. I took it upstairs and knocked on Herr Brandt’s door, one floor above mine. He opened it in a wool cardigan and looked at the key for a long time. “Do you know this?” I asked. “No,” he said, then folded his hands. “I have never seen it.”
This entry is dated 13 January. A note lay under my door when I left for work in the morning. It was written on the back of a tram timetable. “Please bring the key to the top floor at ten tomorrow,” it said. There was no name, but the handwriting was neat and narrow, like the numbers on Herr Brandt’s mailbox. I put the note and the key in a bowl beside my kettle. That evening, I made Kartoffelsuppe and kept looking at the bowl while I ate.
This entry is dated 14 January. At five minutes before ten, I climbed to the top floor with the key in my coat pocket. Herr Brandt was waiting beside a grey metal door I had not noticed before. “You said you had never seen it,” I said. “I had not seen that key,” he replied. “I thought it was lost when the old caretaker left.” He pointed to the lock. “Try it.” The key turned easily, and the door opened onto the roof. Snow lay in thin lines between wooden planting boxes. Dry rosemary and small rose bushes stood above the snow, each marked with a faded wooden sign. A green bench faced the roofs of Leipzig.
This entry is dated 14 January, later. Herr Brandt touched one of the planting boxes with his glove. “The tenants used to grow things here,” he said. “I watered the plants for years, until the roof door was locked.” He looked at the empty boxes, then at me. “Would you like to help when spring comes?” Before I could answer, he opened a thermos from his bag and poured coffee into two blue cups. I took one cup and sat beside him on the green bench. Below us, tram line 10 rang its bell at the stop. Herr Brandt lifted his cup, and snow slipped quietly from the roof door onto the steps.
