A Girl of High Adventure by L.T. Meade

Little Margot soon settled down into the life she loved best. Her object was to please her dear granddad. She was fond of her uncles and her old-young aunts and of dear, stately little Madam, but there was no one in all the world like The Desmond himself.

In her sweet presence he became a sort of child again. He went out, holding her little brown hand, and although it was still too early in the year to gather many flowers, such as grew in profusion in the south of France, they did find wonderful mosses, and the first, sweet, daring crocuses, and snowdrops and even primroses.
