There was a small, square window opening into the bas.e.m.e.nt room of the mill. The young hussar disengaged himself from the saddle and flew through it as the clown goes through the hoops at Franconi's.

An instant later he had opened the door for us, with the blood streaming from his face and hands.

'He has fled up the stair,' said he.

'Then we need be in no hurry, since he cannot pa.s.s us,' said Savary, as we sprang from our horses. 'You have carried his first line of entrenchments most gallantly, Lieutenant Gerard. I hope you are not hurt?'

'A few scratches, General, nothing more.'

'Get your pistols, then. Where is the miller?'

'Here I am,' said a squat, rough little fellow, appearing in the open doorway. 'What do you mean, you brigands, by entering my mill in this fashion? I am sitting reading my paper and smoking my pipe of coltsfoot, as my custom is about this time of the evening, and suddenly, without a word, a man comes flying through my window, covers me with gla.s.s, and opens my door to his friends outside. I've had trouble enough with my one lodger all day without three more of you turning up.'

'You have the conspirator Toussac in your house.'

'Toussac!' cried the miller. 'Nothing of the kind. His name is Maurice, and he is a merchant in silks.'

'He is the man we want. We come in the Emperor's name.'

The miller's jaw dropped as he listened.

'I don't know who he is, but he offered a good price for a bed and I asked no more questions. In these days one cannot expect a certificate of character from every lodger. But, of course, if it is a matter of State, why, it is not for me to interfere. But, to do him justice, he was a quiet gentleman enough until he had that letter just now.'

'What letter? Be careful what you say, you rascal, for your own head may find its way into the sawdust basket.'

'It was a woman who brought it. I can only tell you what I know.

He has been talking like a madman ever since. It made my blood run cold to hear him. There's someone whom he swears he will murder. I shall be very glad to see the last of him.'

'Now, gentlemen,' said Savary, drawing his sword, 'we may leave our horses here. There is no window for forty feet, so he cannot escape from us. If you will see that your pistols are primed, we shall soon bring the fellow to terms.'

The stair was a narrow winding one made of wood, which led to a small loft lighted from a slit in the wall.

Some remains of wood and a litter of straw showed that this was where Toussac had spent his day. There was, however, no sign of him now, and it was evident that he had ascended the next flight of steps.

We climbed them, only to find our way barred by a heavy door.

'Surrender, Toussac!' cried Savary. 'It is useless to attempt to escape us.

A hoa.r.s.e laugh sounded from behind the door.

'I am not a man who surrenders. But I will make a bargain with you.

I have a small matter of business to do to-night. If you will leave me alone, I will give you my solemn pledge to surrender at the camp to-morrow. I have a little debt that I wish to pay. It is only to-day that I understood to whom I owed it.'

'What you ask is impossible.'

'It would save you a great deal of trouble.'

'We cannot grant such a request. You must surrender.'

'You'll have some work first.'

'Come, come, you cannot escape us. Put your shoulders against the door!

Now, all together?'

There was the hot flash of a pistol from the keyhole, and a bullet smacked against the wall between us. We hurled ourselves against the door. It was ma.s.sive, but rotten with age. With a splintering and rending it gave way before us. We rushed in, weapons in hand, to find ourselves in an empty room.

'Where the devil has he got to?' cried Savary, glaring round him.

'This is the top room of all. There is nothing above it.'

It was a square empty s.p.a.ce with a few corn-bags littered about. At the further side was an open window, and beside it lay a pistol, still smoking from the discharge. We all rushed across, and, as we craned our heads over, a simultaneous cry of astonishment escaped from us.

The distance to the ground was so great that no one could have survived the fall, but Toussac had taken advantage of the presence of that cart full of grain-sacks, which I have described as having lain close to the mill. This had both shortened the distance and given him an excellent means of breaking the fall. Even so, however, the shock had been tremendous, and as we looked out he was lying panting heavily upon the top of the bags. Hearing our cry, however, he looked up, shook his fist defiantly, and, rolling from the cart, he sprang on to the back of Savary's black horse, and galloped off across the downs, his great beard flying in the wind, untouched by the pistol bullets with which we tried to bring him down.

How we flew down those creaking wooden stairs and out through the open door of the mill! Quick as we were, he had a good start, and by the time Gerard and I were in the saddle he had become a tiny man upon a small horse galloping up the green slope of the opposite hill.

The shades of evening, too, were drawing in, and upon his left was the huge salt-marsh, where we should have found it difficult to follow him.

The chances were certainly in his favour. And yet he never swerved from his course, but kept straight on across the downs on a line which took him farther and farther from the sea. Every instant we feared to see him dart away in the mora.s.s, but still he held his horse's head against the hill-side. What could he be making for? He never pulled rein and never glanced round, but flew onwards, like a man with a definite goal in view.

Lieutenant Gerard and I were lighter men, and our mounts were as good as his, so that it was not long before we began to gain upon him. If we could only keep him in sight it was certain that we should ride him down; but there was always the danger that he might use his knowledge of the country to throw us off his track. As we sank beneath each hill my heart sank also, to rise again with renewed hope as we caught sight of him once more galloping in front of us.

But at last that which I had feared befell us. We were not more than a couple of hundred paces behind him when we lost all trace of him.

He had vanished behind some rolling ground, and we could see nothing of him when we reached the summit.

'There is a road there to the left,' cried Gerard, whose Gascon blood was aflame with excitement.

'On, my friend, on, let us keep to the left!'

'Wait a moment!' I cried. 'There is a bridle-path upon the right, and it is as likely that he took that.'

'Then do you take one and I the other.'

'One moment, I hear the sound of hoofs!'

'Yes, yes, it is his horse!'

A great black horse, which was certainly that of General Savary, had broken out suddenly through a dense tangle of brambles in front of us.

The saddle was empty.

'He has found some hiding-place here amongst the brambles,' I cried.

Gerard had already sprung from his horse, and was leading him through the bushes. I followed his example, and in a minute or two we made our way down a winding path into a deep chalk quarry.

'There is no sign of him!' cried Gerard. 'He has escaped us.'

But suddenly I had understood it all. His furious rage which the miller had described to us was caused no doubt by his learning how he came to be betrayed upon the night of his arrival. This sweetheart of his had in some way discovered it, and had let him know. His promise to deliver himself up to-morrow was in order to give him time to have his revenge upon my uncle. And now with one idea in his head he had ridden to this chalk quarry. Of course, it must be the same chalk quarry into which the underground pa.s.sage of Grosbois opened, and no doubt during his treasonable meetings with my uncle he had learned the secret. Twice I hit upon the wrong spot, but at the third trial I gained the face of the cliff, made my way between it and the bushes, and found the narrow opening, which was hardly visible in the gathering darkness. During our search Savary had overtaken us on foot, so now, leaving our horses in the chalk-pit, my two companions followed me through the narrow entrance tunnel, and on into the larger and older pa.s.sage beyond. We had no lights, and it was as black as pitch within, so I stumbled forward as best I might, feeling my way by keeping one hand upon the side wall, and tripping occasionally over the stones which were scattered along the path. It had seemed no very great distance when my uncle had led the way with the light, but now, what with the darkness, and what with the uncertainty and the tension of our feelings, it appeared to be a long journey, and Savary's deep voice at my elbow growled out questions as to how many more miles we were to travel in this moleheap.

'Hush!' whispered Gerard. 'I hear someone in front of us.'

We stood listening in breathless silence. Then far away through the darkness I heard the sound of a door creaking upon its hinges.

'On, on!' cried Savary, eagerly. 'The rascal is there, sure enough.

This time at least we have got him!'
