Winter came early, and was very cold. Ammi saw Nahum less often than usual, and observed that he had begun to look worried. The rest of his family too, seemed to have grown taciturn; and were far from steady in their church-going or their attendance at the various social events of the countryside. For this reserve or melancholy no cause could be found, though all the household confessed now and then to poorer health and a feeling of vague disquiet. Nahum himself gave the most definite statement of anyone when he said he was disturbed about certain footprints in the snow. They were the usual winter prints of red squirrels, white rabbits, and foxes, but the brooding farmer professed to see something not quite right about their nature and arrangement.
