As you are aware, the mob took possession of the prisons, chose three so-called judges to pass sentence upon the unhappy aristocrats, and then tore them to pieces when they were passed out into the street. My father had been a benefactor of the poor all his life. There were many to plead for him. He had the fever, too, and was carried in, half-dead, upon a blanket. Two of the judges were in favour of acquitting him; the third, a young Jacobin, whose huge body and brutal mind had made him a leader among these wretches, dragged him, with his own hands, from the litter, kicked him again and again with his heavy boots, and hurled him out of the door, where in an instant he was torn limb from limb under circumstances which are too horrible for me to describe. This, as you perceive, was murder, even under their own unlawful laws, for two of their own judges had pronounced in my father's favour.

'Well, when the days of order came back again, my elder brother began to make inquiries about this man. I was only a child then, but it was a family matter, and it was discussed in my presence. The fellow's name was Carabin. He was one of Sansterre's Guard, and a noted duellist. A foreign lady named the Baroness Straubenthal having been dragged before the Jacobins, he had gained her liberty for her on the promise that she with her money and estates should be his. He had married her, taken her name and title, and escaped out of France at the time of the fall of Robespierre. What had become of him we had no means of learning.

'You will think, doubtless, that it would be easy for us to find him, since we had both his name and his title. You must remember, however, that the Revolution left us without money, and that without money such a search is very difficult. Then came the Empire, and it became more difficult still, for, as you are aware, the Emperor considered that the 18th Brumaire brought all accounts to a settlement, and that on that day a veil had been drawn across the past. None the less, we kept our own family story and our own family plans.

'My brother joined the army, and passed with it through all Southern Europe, asking everywhere for the Baron Straubenthal. Last October he was killed at Jena, with his mission still unfulfilled. Then it became my turn, and I have the good fortune to hear of the very man of whom I am in search at one of the first Polish villages which I have to visit, and within a fortnight of joining my regiment. And then, to make the matter even better, I find myself in the company of one whose name is never mentioned throughout the army save in connection with some daring and generous deed.'

This was all very well, and I listened to it with the greatest interest, but I was none the clearer as to what young Duroc wished me to do.

'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.
