"Just so! And now you have come round to the meaning of Anne’s letter!" Sophie proclaimed, and flogged the parchment several times with her ivory fan. At the same time, the tree-wall behind them let out a gasp as it was struck by a fist of cold air. The wind had changed from south to west; new weather was coming; Herr Schwartz’s joints had not misled him. The tree-wall flexed toward them as if trying to spread shelter above their heads, and a dry sleet of brown leaves and twigs made the air and the ground restless with tiny itchings and fidgetings. Sophie—who of all persons was least disposed to take a fart for a thunderclap—paid this no heed whatever. Perhaps she was too absorbed in conversation to care. Or perhaps she was so comfortable in this place that she could not muster any sense of concern.
