Those of our readers who have met the Castletons before in The Head Girl at the Gables, will remember that they were a very large family. Morland, the eldest, had been at the war, had won the D.C.M., and was now learning engineering; Claudia was studying singing in London; Madox had been sent for his first term at boarding-school; and the four little ones, Constable, Lilith, Perugia, and Gabriel, were still in the nursery. There was only one gap. Landry, poor Landry, who had never been like other boys, had passed over the divide and joined the beautiful mother whom in features he had so strongly resembled. A painting of him, as a little child in her arms, hung on the studio wall. In some respects it was the most brilliant portrait which Mr. Castleton had ever achieved. He always showed it to visitors as a specimen of his best work.

At the time this story begins, Beata and Romola were fourteen and thirteen years of age. They thoroughly maintained the family reputation for good looks. There was a certain resemblance between them, and yet a difference. Beata's eyes were clear grey, with dark lines round the iris, and her hair was the exact shade of one of her father's best English gold picture frames. She was a clever, capable girl, with a great love for music, and was beginning to play the violin rather well. She got on quite tolerably with her stepmother, and was fond of the little half-brothers and sisters, though the warmest corner of her heart was reserved for Madox, who was the baby of the elder portion of the family.

Romola, blue-eyed and ethereal, with long amber hair like a Saxon princess, was her father's favourite model whenever he wished to depict scenes of olden times. She figured as 'Guinevere' in a series of illustrations to the Morte d'Arthur, as 'Elaine' her portrait had been exhibited in the Academy, as 'The Lady of Shalott' she had appeared in a coloured frontispiece of The Art Review, she inspired a most successful poster of 'Cinderella,' and was the original of a series of fairy drawings in a children's annual. She was not so clever or go-ahead as Beata, and was rather dreamy and romantic in temperament, with a gift towards painting and poetry, and a disinclination to do anything very definite. She left most of the problems of life to Beata, and seldom troubled to make decisions for herself. She was rather a pet with Violet, her young stepmother, who, while preferring her to her sister, found her the less useful of the two.

"You go, Beata, you're so quick!" Violet would say, when she wanted an errand done, and for the same reason gave the charge of the children to the one who was the more capable of assuming the responsibility.

It was not that Romola consciously shirked home duties, but she would any time rather pose for an hour on the throne in the studio than take temporary command of the nursery. Beata, on the contrary, hated sitting still, and considered there was no greater penance than to be commandeered by her father as a model. Her energetic temperament liked to find its expression in outdoor activities. She had set to work upon the neglected garden, and was busy trying to make flower-beds, and she looked forward keenly to the forthcoming hockey season at school. The daily drive to Durracombe and back was pure delight, and formed her greatest compensation for leaving Porthkeverne and The Gables.

The Haven, as the house occupied by the Castletons was called, had been changed into its present form by an old retired sea-captain, and there was much about it that suggested a nautical atmosphere. The panelled walls of the parlour might have been taken from a ship's cabin, the dining-room contained convenient lockers, there was a small observatory upstairs built to accommodate a big telescope, and the figure-head of a vessel adorned the garden. Young Mrs. Castleton, whose tastes inclined towards up-to-date comforts, often grumbled at its inconveniences, but on the whole the family liked it. They would not have exchanged it for a suburban villa for worlds. Just on the opposite side of the harbour, with the jetty and the broad strip of green water in between, was the furnished house rented at present by the Macleods. It stood in the more aristocratic portion of Chagmouth, apart from the town and the fishing, in company with one or two other newly-built residences. It was charmingly pretty and artistic, in a perfectly modern fashion, and had been designed by a famous architect. Its owner, a retired naval officer, had gone abroad for a year, and had let the place in his absence, rejoicing to have secured a careful tenant. He might certainly congratulate himself upon leaving his house in such good hands. Mr. Macleod was an American gentleman, who, owing to a nervous breakdown, was travelling in Europe, and happening in the course of the summer to wander to Chagmouth, he had fallen in love with the quaint old town and had decided to spend the winter there. The factor which largely influenced this decision was the presence of Mr. Castleton. Mr. Macleod was an enthusiastic amateur painter, and the prospect of being able to take lessons from so good an artist was sufficient to chain him to Chagmouth. His wife encouraged the idea.

"George is just miserable if he's nothing to do," she explained to her friends. "The doctor told me not to let him read too much or take up any special mental hobby, but sketching strikes the happy medium. He thoroughly enjoys pottering about in Mr. Castleton's studio, or making drawings down on the quay. It's not arduous work and yet it keeps him occupied. I like the house, and Fay can go to school near, so I expect we're fixed here until next spring at any rate. If I get too bored I shall run over to Paris and see my sister, but really I haven't been well lately myself, and it will do me good to take a thorough rest for a while."

Fay, who had formed an enthusiastic friendship with Beata and Romola, was as pleased with Chagmouth as her parents. From the windows of Bella Vista she could look across the harbour to The Haven, and had already arranged a code of signals by which she might communicate with her chums. She was a bright, amusing girl, rather grown-up for her age, and the constant companion of her father and mother.

"Fay runs the house!" Mrs. Macleod would declare sometimes; but she was immensely proud of her young daughter, and unwilling to thwart her in any of the projects which she might care to take up. These, indeed, were many. Fay dabbled in numerous hobbies, and her demands varied from photographic materials to special sandals for toe dancing. She thoroughly enjoyed life, and the freshness of her enthusiasm provided her parents with a perpetual interest. To those friends who urged boarding-school her mother was ready with the reply:

"Why must we be parted from her? She's her father's best tonic! She keeps him young and makes him laugh. She's getting her education and living her home life at the same time, and that seems to me ideal. We shall probably have to spare her later on to be married, so we may as well make the most of her now while we've got her. It's the chief tragedy of parents that the children grow up and go away. We'll enjoy our nest while we have our one chick here. When the young ones are fledged, the old birds stop singing."
