The Witch of Prague by F. Marion Crawford

After leaving Unorna at the convent, the Wanderer had not hesitated as to the course he should pursue. It was quite clear that the only person to whom he could apply at the present juncture was Keyork Arabian. Had he been at liberty to act in the most natural and simple way, he would have applied to the authorities for a sufficient force with which to take Israel Kafka into custody as a dangerous lunatic. He was well aware, however, that such a proceeding must lead to an inquiry of a more or less public nature, of which the consequences might be serious, or at least extremely annoying, to Unorna. Of the inconvenience to which he might himself be exposed, he would have taken little account, though his position would have been as difficult to explain as any situation could be. The important point was to prevent the possibility of Unorna's name being connected with an open scandal.

Every present circumstance in the case was directly or indirectly the result of Unorna's unreasoning passion for himself, and it was clearly his duty, as a man of honour, to shield her from the consequences of her own acts, as far as lay in his power.
