"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."
Nigel clapped his hands with joy. "'Fore God!" he cried. "It is a most noble plan! But alas! Simon, I see not how we can tell the course of this passage or where we should dig."
"I have peasants yonder with spades," said Simon. "There are two of my friends, Harding of Barnstable and West-country John who are waiting for us with their gear. If you will come to lead us, Squire Nigel, we are ready to venture our bodies in the attempt."
What would Knolles say in case they failed? The thought flashed through Nigel's mind, but another came swiftly behind it. He would not venture further unless he found hopes of success. And if he did venture further he would put his life upon it. Giving that, he made amends for all errors. And if on the other hand success crowned their efforts, then Knolles would forgive his failure at the gateway. A minute later, every doubt banished from his mind, he was making his way through the darkness under the guidance of Black Simon.
