"A ghost! It is a ghost!" he exclaimed in French.

But a second look told Achille Garay that it was no ghost. It may have been a miracle, but it was Robert Lennox come back in the flesh, and his finger returned to the trigger. Another was quicker. The hunter saw him.

"That for you, Garay!" he cried, and sent a bullet through the spy's heart. Then, drawing the two lads with him, he rushed forward in pursuit.

The confusion in the French army was increasing. Its defeat was fast becoming a rout, but some of the officers still strove to stay the panic. Robert saw one on a white horse gallop before a huddle of fleeing men. But the soldiers, swerving, ran on. A bullet struck the horse and he fell. The man leaped clear, but looked around in a dazed manner. Then a bullet struck him too, and he staggered. Robert with a cry rushed forward, and received into his arms the falling figure of St. Luc.

He eased the Chevalier to the ground and rested his head upon his knee.

"He isn't dead!" he exclaimed. "He's only shot through the shoulder!"

"Now, this is in truth the hand of Providence," said Willet gravely, "when you are here in the height of a great battle to break the fall of your own uncle!"

"My uncle!" exclaimed Robert.

The Chevalier Raymond Louis de St. Luc smiled wanly.

"Yes, my nephew," he said, "your own uncle, though wounded grievously, on this the saddest of all days for France, son of my dear, dead sister, Gabrielle."
