At the moment that I pen these final lines the pair are spending a blissful honeymoon at the great old château of Hetzendorf, high up above the broad-flowing Danube, the Baron having kindly vacated the place and put it at their disposal for the summer. Happy in each other's love and mutual trust, they spend the long blissful days in company, wandering often hand in hand, for when Walter looks into those wonderful eyes of hers he sees mirrored there a perfect and abiding affection such as is indeed given few men to possess. Together they have in secret explored the ruins of the ancient stronghold, and, by directions given them by the Baron, have found there a stone chamber by no means dissimilar to that at Glencardine. Meanwhile, Sir Henry Heyburn, impatient for his beloved daughter to be again near him and to assist him, passes his weary hours with his favourite hobby; his wife, full of sympathy, bearing him company. From her, however, he still withholds one secret, and one only--the Secret of the House of Whispers.
