Every winter, the Zelverhauses, a wealthy family of tea merchants, hosted the clocksmith at their country home for the parties and entertainments given during the week of Nachtspel. The house itself was a model of merchant restraint, all dark wood, stolid brick, and hard lines. But it was perfectly situated by a lake that froze early for skating, and it was effusive in its comforts, with fireplaces alight in each room to keep the house always snug and merry, and every floor polished to the warm syrup shine of a glazed cake.
