The Ghost of Guir House, by Charles Willing Beale app for iPhone and iPad

Whatever may have been Mr. Henleys suspicions concerning the implication of the Guirs with the crime which he could no longer doubt had been committed in their house, they were promptly dispelled, so far as the young lady was concerned, upon meeting Dorothy at the breakfast table. Her innocent though serious face was a direct rebuke to any distrust he might have entertained; and he even doubted if she had any knowledge of the state of things he had discovered in the vault. This, of course, only added to the mystery; nor was Mr. Henleys self-esteem fortified by the memory of how unscrupulously he had become the guest of these people, and of how equivocal had been his treatment of their hospitality.
