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 morass, 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.
