“But what has this to do with Aylward?”
“I will show you. This evening after the assault I chanced to walk with some of my fellows, round yonder small fort upon the knoll to see if we could spy a weak spot in it. Some of them came to the wall to curse us, and among them whom should I see but a big man with a white face, red hair and a touch of Anthony’s fire upon his cheek? What make you of that, Squire Nigel?”
“That this man had crossed from the castle to the fort.”
“In good sooth, it must indeed be so. There are not two such ken-speckled men in the world. But if he crossed from the castle to the fort, it was not above the ground, for our own people were between.”
“By Saint Paul! I see your meaning!” cried Nigel. “It is in your mind that there is a passage under the earth from one to the other.”
“I am well sure of it.”
“Then if we should take the small fort we may pass down this tunnel, and so carry the great castle also.”
“Such a thing might happen,” said Simon, “and yet it is dangerous also, for surely those in the castle would hear our assault upon the fort and so be warned to bar the passage against us, and to slay the prisoners before we could come.”
“What then is your rede?”
“Could we find where the tunnel lay, Squire Nigel, I know not what is to prevent us from digging down upon it and breaking into it so that both fort and castle are at our mercy before either knows that we are there.”
