Love and Hatred by Marie Belloc Lowndes

Laura and Oliver Tropenell walked across the grass in silence, and still in silence they passed through under the great dark arch formed by the beech trees.

Laura was extraordinarily moved and excited. Her brother, her dear, dear Gillie, coming home? She had taken the surprising news very quietly, but it had stirred her to the depths of her nature. Without even telling her of what he was going to do, the man now walking by her side had brought about the thing that for years she had longed should come to pass.
