My task was done. I had tracked this weak, vain, erring, hunted soul to its last refuge, and the knowledge bequeathed to me but a single duty. His sins were balanced by his temptations; his vanity and weakness had revenged themselves; and there only remained to tell the simple, faithful sister that her sacrifices were no longer required. I burned the evidences of guilt, despair and suicide, and sent the other papers, with a letter relating the time and circumstances of Otto Lindenschmidt's death, to the civil authorities of Breslau, requesting that they might be placed in the hands of his sister Elise.

This, I supposed, was the end of the history, so far as my connection with it was concerned. But one cannot track a secret with impunity; the fatality connected with the act and the actor clings even to the knowledge of the act. I had opened my door a little, in order to look out upon the life of another, but in doing so a ghost had entered in, and was not to be dislodged until I had done its service.

In the summer of 1867 I was in Germany, and during a brief journey of idlesse and enjoyment came to the lovely little watering-place of Liebenstein, on the southern slope of the Thuringian Forest. I had no expectation or even desire of making new acquaintances among the gay company who took their afternoon coffee under the noble linden trees on the terrace; but, within the first hour of my after-dinner leisure, I was greeted by an old friend, an author, from Coburg, and carried away, in my own despite, to a group of his associates. My friend and his friends had already been at the place a fortnight, and knew the very tint and texture of its gossip. While I sipped my coffee, I listened to them with one ear, and to Wagner's overture to “Lohengrin” with the other; and I should soon have been wholly occupied with the fine orchestra had I not been caught and startled by an unexpected name.

“Have you noticed,” some one asked, “how much attention the Baron von Herisau is paying her?”

I whirled round and exclaimed, in a breath, “The Baron von Herisau!”

“Yes,” said my friend; “do you know him?”

I was glad that three crashing, tremendous chords came from the orchestra just then, giving me time to collect myself before I replied: “I am not sure whether it is the same person: I knew a Baron von Herisau long ago: how old is the gentleman here?”

“About thirty-five, I should think,” my friend answered.

“Ah, then it can't be the same person,” said I: “still, if he should happen to pass near us, will you point him out to me?”

It was an hour later, and we were all hotly discussing the question of Lessing's obligations to English literature, when one of the gentlemen at the table said: “There goes the Baron von Herisau: is it perhaps your friend, sir?”
