CHAPTER XV.  The Banshee.—­Disappearance of Grace Davoren.

In the meantime it was certainly an unquestionable fact that Grace Davoren had disappeared, and not even a trace of her could be found.  The unfortunate girl, alarmed at the tragic incident of that woful night, and impressed with a belief that Charles Lindsay had been murdered by Shawn-na-Middogue, had betaken herself to some place of concealment which no search on behalf of her friends could discover.  In fact, her disappearance was involved in a mystery as deep as the alarm and distress it occasioned.  But what astonished the public most was the fact that Charles, whose whole life had been untainted by a single act of impropriety, much less of profligacy, should have been discovered in such a heartless and unprincipled intrigue with the daughter of one of his father’s tenants, an innocent girl, who, as such, was entitled to protection rather than injury at his hands.

Whilst this tumult was abroad, and the country was in an unusual state of alarm and agitation, Harry Woodward took, matters very quietly.  That he seemed to feel deeply for the uncertain and dangerous state of his brother, who lay suspended, as it were, between life and death, was evident to every individual of his family.  He frequently took Caterine Collins’s place, attended him personally, with singular kindness and affection, gave him his drinks and decoctions with his own hand; and, when the surgeon came to make his daily visit, the anxiety he evinced in ascertaining whether there was any chance of his recovery was most affectionate and exemplary.  Still, as usual, he was out at night; but the mystery of his whereabouts, while absent, could never be penetrated.  On those occasions he always went armed—­a fact which he never attempted to conceal.  On one of these nights it so happened that Barney Casey was called upon to attend at the wake of a relation, and, as his master’s family were apprised of this circumstance, they did not of course expect him home until a late hour.  He left the wake, however, earlier than he had proposed to do, for he found it a rather dull affair, and was on his way home when, to his astonishment, or rather to his horror, he saw Harry Woodward—­also on his way home—­in close conversation with the supernatural being so well known by description as the Shan-dhinne-dhuv; or Black Spectre.  Now, Barney was half cowardly and half brave—­that is to say, had he lived in an enlightened age he would have felt little terror of supernatural appearances; but at the period of our story such was the predominance of a belief in ghosts, fairies, evil spirits, and witches, that he should have been either less or more than man could he have shaken off the prevailing superstitions, and the gross credulity of the times in which he lived.  As it was, he knew not what to think.  He remembered the character which had been whispered abroad about
