The Bishop's Secret by Fergus Hume

Although the palace was so near Beorminster, and the sphere of Gabriel's labours lay in the vicinity of the cathedral, Bishop Pendle did not judge it wise that his youngest son should dwell beneath the paternal roof. To teach him independence, to strengthen his will and character, and because he considered that a clergyman should, to a certain extent, share the lot of those amongst whom he laboured, the bishop arranged that Gabriel should inhabit lodgings in the old town, not far from The Derby Winner. It was by reason of this contiguity that Gabriel became acquainted with the handsome barmaid of the hotel, and as he was a more weak-natured man than his father dreamed of, it soon came about that he fell in love with the girl. Matters between them had gone much further than even Cargrim with all his suspicions guessed, for in the skilful hands of Miss Mosk the curate was as clay, and for some time he had been engaged to his charmer.

No one knew this, not even Mrs Mosk, for the fair Bell was quite capable of keeping a secret; but Gabriel was firmly bound to her by honour, and Bell possessed a ring, which she kept in the drawer of her looking-glass and wore in secret, as symbolic of an engagement she did not dare to reveal.
