"Eustace de Brin never turned a deaf ear to the pleading of a friend," he said in a quieter tone. "For our friendship's sake, then, if thou dost intercede for their lives' on behalf of thy wife I will listen. If 'tis for aught else I will not move one single hair's breadth from my purpose."

"Hearest thou, Beatrice? Wilt thou----?"

De Maupas stopped and looked enquiringly at his formidable companion. De Brin had given a sudden start, and appeared to be gazing at the window with an intent expression on his face.

Roused by De Maupas's sudden silence, Beatrice lifted her face from her hands and looked at the two men. Both were listening intently, and she caught a sound as of the winding of a distant horn. It ceased as though broken off short, and the two men looked significantly at one another.

"Didst hear?" said De Maupas laconically.

"Yes--an attack," growled De Brin, grinding his teeth with fury. "So much the worse for the attackers. Come--to horse, De Maupas; we have tarried with this obstinate girl too long already;" and with a dark look at Beatrice, De Brin hurried from the room, followed closely by his companion. The moment they were gone Beatrice rushed to the window and peered eagerly out. The trampling of steeds on the flagstones of the courtyard, the winding of horns, and the shouting and cheering of the men-at-arms indicated that the garrison were about to issue forth in force. Clearly something had occurred to alarm the inmates of the castle seriously. What could it be? Think as she would, Beatrice could find no satisfactory answer.

CHAPTER XIX

The Assault

"The dam is down!" cried Father Armand excitedly, rejoining Edgar in the woods opposite the castle gateway as the latter was superintending the construction of two great mangonels. "The dam is down and the water is rushing away like a mill sluice."

"'Tis well," replied Edgar; "in an hour or so the moat will be half-empty, and we can begin to make ready for the first assault."
