Anna the Adventuress by E. Phillips Oppenheim

Sir John, in a quiet dark travelling suit, was sitting in a pokey little room writing letters. The room was worse than pokey, it was shabby; and the view from the window, of chimney pots and slate roofs, wholly uninspiring. Nevertheless, Sir John had the look of a man who was enjoying himself. He seemed years younger, and the arrangement of his tie and hair were almost rakish. He stamped his last letter as Annabel entered.

She was dressed for the street very much as her own maid was accustomed to dress, and there was a thick veil attached to her hat.
