"You are like 'John Don't-know' in the fairy tale. He always answered, 'I don't know' to everything that was asked him. Of course you don't know the two witnesses either who could establish your innocence? In that case, my good fellow, you're no better off than you were before."
"But I do know one of them."
"What is his name?"
"Oh, I don't know his name."
"Well, how do you know him, then?"
"He has three hairs at the end of his nose."
"Rubbish! He may have cut them off since then."
"I should know him all the same by his face; it is just like an owl's."
"And where did you pick up the two masons?"
"They were mending the wall of the parish church."
