"Can you in that case expect the witness to come forward?"
"To prevent the condemnation of an innocent man? Yes, I think I may venture to expect even that."
"I repeat—why are you telling me all this?"
"Because, Mrs. Grimethorpe, you know, even better than I, how innocent my brother is of this murder. Believe me, I am deeply distressed at having to say these things to you."
"I know nothing about your brother."
"Forgive me, that is not true."
"I know nothing. And surely, if the Duke will not speak, you should respect his reasons."
"I am not bound in any way."
"I am afraid I cannot help you. You are wasting time. If you cannot produce your missing witness, why do you not set about finding the real murderer? If you do so you surely need not trouble about this alibi. Your brother's movements are his own business."
"I could wish," said Wimsey, "you had not taken up this attitude. Believe me, I would have done all I could to spare you. I have been working hard to find, as you say, the real murderer, but with no success. The trial will probably take place at the end of the month."
