ten o'clock
Toward evening a mild breeze freshened from the southwest . The tender blue of the sky faded at sundown to a slaty gray . Long wraiths of cloud floated up with the rising wind . At ten o'clock a gale whooped riotously through the trees . And at midnight Hazel wakened to a sound that she had not heard in months . She rose and groped her way to the window . The encrusting frost had vanished from the panes .
