‘How can I be of service to you?’ I asked.

‘By coming up with me.’

‘To the Castle?’

‘Precisely.’

‘When?’

‘At once.’

‘But what do you intend to do?’

‘I shall know what to do.  But I wish you to be with me, all the same.’

Well, it was never in my nature to refuse an adventure, and, besides, I had every sympathy with the lad’s feelings.  It is very well to forgive one’s enemies, but one wishes to give them something to forgive also.  I held out my hand to him, therefore.

’I must be on my way for Rossel tomorrow morning, but tonight I am yours,’ said I.

We left our troopers in snug quarters, and, as it was but a mile to the Castle, we did not disturb our horses.  To tell the truth, I hate to see a cavalry man walk, and I hold that just as he is the most gallant thing upon earth when he has his saddle-flaps between his knees, so he is the most clumsy when he has to loop up his sabre and his sabre-tasche in one hand and turn in his toes for fear of catching the rowels of his spurs.  Still, Duroc and I were of the age when one can carry things off, and I dare swear that no woman at least would have quarrelled with the appearance of the two young hussars, one in blue and one in grey, who set out that night from the Arensdorf post-house.  We both carried our swords, and for my own part I slipped a pistol from my holster into the inside of my pelisse, for it seemed to me that there might be some wild work before us.

The track which led to the Castle wound through a pitch-black fir-wood, where we could see nothing save the ragged patch of stars above our heads.  Presently, however, it opened up, and there was the Castle right in front of us, about as far as a carbine would carry.  It was a huge, uncouth place, and bore every mark of being exceedingly old, with turrets at every corner, and a square keep on the side which was nearest to us.  In all its great shadow there was no sign of light save from a single window, and no sound came from it.  To me there was something awful in its size and its silence, which corresponded so well with its sinister name.  My companion pressed on eagerly, and I followed him along the ill-kept path which led to the gate.

There was no bell or knocker upon the great iron-studded door, and it was only by pounding with the hilts of our sabres that we could attract attention.  A thin, hawk-faced man, with a beard up to his temples, opened it at last.  He carried a lantern in one hand, and in the other a chain which held an enormous black hound.  His manner at the first moment was threatening, but the sight of our uniforms and of our faces turned it into one of sulky reserve.

‘The Baron Straubenthal does not receive visitors at so late an hour,’ said he, speaking in very excellent French.

’You can inform Baron Straubenthal that I have come eight hundred leagues to see him, and that I will not leave until I have done so,’ said my companion.  I could not myself have said it with a better voice and manner.
