The Diva's Ruby by F. Marion Crawford

The _Erinna_ was steaming quietly down the Channel in a flat calm, at the lazy rate of twelve knots an hour, presumably in order to save her coal, for she could run sixteen when her owner liked, and he was not usually fond of going slow. Though September was at hand, and Guernsey was already on the port quarter, the sea was motionless and not so much as a cat's-paw stirred the still blue water; but the steamer's own way made a pleasant draught that fanned the faces of Logotheti and Baraka as they lay in their long chairs under the double awning outside the deck-house.

The Tartar girl wore a skirt and jacket of dark blue yachting serge, which did not fit badly considering that they had been bought ready-made by Logotheti's man. She had little white tennis shoes on her feet, which were crossed one over the other on the deck-chair, but instead of wearing a hat she had bound a dove-coloured motor-veil on her head by a single thick gold cord, in the Asiatic way, and the thin folds hung down on each side, and lay on her shoulders, shading her face, and the breeze stirred them. Logotheti's valet had been sent out in a taximeter, provided with a few measurements and plenty of cash, and commissioned to buy everything that a girl who had nothing at all to wear, visible or invisible, could possibly need. He was also instructed to find a maid who could speak Tartar, or at least a little Turkish.
