The Disappearance of Lady Frances Carfax

Lady Frances Carfax has abruptly left her room at the Hôtel National in Lausanne and has not been heard of for weeks. Had she not been a woman, she would have been set to inherit a large amount of money. Nevertheless, she is known to have expensive jewellery. Watson comes to Switzerland to investigate as Holmes has to stay in London. His only clue is that a bearded man was pestering her. "The Disappearance of Lady Frances Carfax" is part of "His Last Bow".
