Something in the big eyes, bigger and blacker than ever in the thin white face, fixed, so steadily on one object, had a sort of fascination for Mrs Jo after a time, and she watched the changes in them curiously; for Dan's mind was evidently not on the story, and he often forgot to laugh or exclaim at the comic or exciting crises. Sometimes they were soft and wistful, and the watcher was very glad that neither damsel caught that dangerous look for when they spoke it vanished; sometimes it was full of eager fire, and the colour came and went rebelliously, in spite of his attempt to hide it with an impatient gesture of hand or head; but oftenest it was dark, and sad, and stern, as if those gloomy eyes looked out of captivity at some forbidden light or joy. This expression came so often that it worried Mrs Jo, and she longed to go and ask him what bitter memory overshadowed those quiet hours. She knew that his crime and its punishment must lie heavy on his mind; but youth, and time, and new hopes would bring comfort, and help to wear away the first sharpness of the prison brand. It lifted at other times, and seemed almost forgotten when he joked with the boys, talked with old friends, or enjoyed the first snows as he drove out every fair day. Why should the shadow always fall so darkly on him in the society of these innocent and friendly girls? They never seemed to see it, and if either looked or spoke, a quick smile came like a sunburst through the clouds to answer them. So Mrs Jo went on watching, wondering, and discovering, till accident confirmed her fears. Josie was called away one day, and Bess, tired of working, offered to take her place if he cared for more reading. 'I do; your reading suits me better than Jo's. She goes so fast my stupid head gets in a muddle and soon begins to ache. Don't tell her; she's a dear little soul, and so good to sit here with a bear like me.' The smile was ready as Bess went to the table for a new book, the last story being finished. 'You are not a bear, but very good and patient, we think. It is always hard for a man to be shut up, mamma says, and must be terrible for you, who have always been so free.' If Bess had not been reading titles she would have seen Dan shrink as if her last words hurt him. He made no answer; but other eyes saw and understood why he looked as if he would have liked to spring up and rush away for one of his long races up the hill, as he used to do when the longing for liberty grew uncontrollable. Moved by a sudden impulse, Mrs Jo caught up her work-basket and went to join her neighbours, feeling that a non-conductor might be needed; for Dan looked like a thundercloud full of electricity. 'What shall we read, Aunty? Dan doesn't seem to care. You know his taste; tell me something quiet and pleasant and short. Josie will be back soon,' said Bess, still turning over the books piled on the centre-table.
