"And as to this individual document, Mr. Usbech might have signed it in your presence, for anything you know to the contrary?"
"He might have done so."
"Now, on your oath, Kenneby, is your memory strong enough to enable you to give the jury any information on this subject upon which they may firmly rely in convicting that unfortunate lady of the terrible crime laid to her charge." Then for a moment Kenneby glanced round and fixed his eyes upon Lady Mason's face. "Think a moment before you answer; and deal with her as you would wish another should deal with you if you were so situated. Can you say that you remember that Usbech did not sign it?"
"Well, sir, I don't think he did."
"But he might have done so?"
"Oh, yes; he might."
"You do not remember that he did do so?"
"Certainly not."
"And that is about the extent of what you mean to say?"
"Yes, sir."
