What was in Edmund's locket? A Picture of his sweetheart?

The locket belonged to Octavie, who'd put it around his neck when he'd left for war. It held pictures of her parents inside.

The letter had made Edmond heart sick and home sick. He stretched himself on his back and looked straight up at the blinking stars. But he was not thinking of them nor of anything but a certain spring day when the bees were humming in the clematis; when a girl was saying good bye to him. He could see her as she unclasped from her neck the locket which she fastened about his own. It was an old fashioned golden locket bearing miniatures of her father and mother with their names and the date of their marriage. It was her most precious earthly possession.
