But the claims even of righteous claimants are apt to become wearisome to the public, and the interest in them dies away unless it is now and again fanned into a flame.  The Duke of Normandy found it so, and devised a new means of attracting attention.  Although he had gone with his followers to return his grateful thanks to God at the shrine of St. Arnould, he was not a member of the Roman Catholic Church, but he discovered the error of his past ways, and was desirous to embrace the orthodox faith.  Accordingly, he was openly received as a disciple and proselyte in the church of St. Roche.  His conversion was followed by that of his wife and children; but it cost him a very good friend.  It was hoped that the governess would have consented to change her creed with the others.  But the Swiss girl was a good and conscientious Protestant, and this wholesale conversion aroused her suspicions as to the cause in which she was engaged; she reviewed the pretensions of the duke a little more judiciously than she had ever done before, and as the result of her investigations, threw up her post and returned to her father, convinced that she had been ignorantly aiding an imposture.

But if he lost a very efficient assistant, he gained many partizans who had only refrained from acknowledging him previously by a fear lest the throne should be snatched from the Catholic party.  These late adherents came to pay their homage bringing gifts, and their accession to his ranks and their contributions to his purse stimulated the duke to still more ostentatious displays of regal magnificence.  His court grew to an alarming size, and at last a hint was sent from the prefecture of police, that if he did not moderate his pretensions, and behave with greater circumspection, it would be necessary for him to have an interview with the judges of the Assize Court.  The threat was quite sufficient.  Nauendorff withdrew to a quiet abode in the Rue Guillaume, and granted his interviews in a more secret manner.  Indeed, from open clamour he turned to underhand plotting, and so mysterious was his conduct that his landlord requested him to betake himself elsewhere.  He found a yet more retired asylum, and still more suspicious-looking friends, until the police began to suspect that a conspiracy was on foot, and favoured him with a domiciliary visit.  They seized his papers and read them; but they treated him with no great severity.  They hired three places in the diligence which, in 1838, travelled between Paris and Calais.  The duke occupied one of these seats, and two police agents the others, and when they reached the famous little port, his attendants placed him on board the English packet, and watched her speeding towards Dover with the prisoner of the Temple as a present to the English nation.
