Having learnt so much, Lady Newborough being in Paris in the year 1823, had recourse to a stratagem by which she expected to gain additional information. Accordingly she inserted in the newspapers, "that she had been desired by the Countess Pompeo Borghi to discover in France a Count Louis Joinville, who in the year 1773 was with his Countess at Modigliana, where the latter gave birth to a son on the 16th April, and that if either of these persons were still alive, or the child born at Modigliana, she was empowered to communicate to them something of the highest importance. Subsequently to this advertisement, she was waited upon by a Colonel Joinville, but he derived his title only from Louis XVIII. But before the Colonel was out of the door, she had a call from the Abbe de Saint-Fare, whom she gave to understand that she was anxious to discover the identity of a birth connected with the sojourn with the late Comte de Joinville. In the course of conversation, this Abbe is stated to have made most injudicious admissions, from which Lady Newborough gathered that he was the confidential agent of the Duke of Orleans, being currently said to be his illegitimate brother. Lady Newborough was now convinced in her own mind that she was the eldest child of the late Duke of Orleans, and hence was the first princess of the blood of France, and the rightful heiress of immense wealth. But this discovery brought her no happiness, and subjected to her to much discomfort and misery. Her story--whether true or false--will in all probability remain a mystery to the end of time, being one of those political puzzles which must remain an open question.
