"In my opinion the judge was right. I do not think Penreath is insane, or even subject to fits of impulsive insanity. If you ask my opinion, I think he is still suffering from the effects of shell shock, and, like many other brave men who have been similarly affected, he endeavoured to conceal the fact. I have come to the conclusion that Penreath's peculiar conduct at the Durrington hotel, on which Sir Henry based his theory of _furor epilepticus_, was nothing more than the combined effect of mental worry and an air raid shock on a previously shattered nervous system. Penreath is a sane man--as sane as you or I--and my late investigations at the scene of the murder have convinced me that he is an innocent man also. The question is, are you going to allow professional etiquette to stand in the way of proving his innocence?" "But you have not shown me anything to convince me that he _is_ an innocent man. Your statement comes as a great surprise to me, and you cannot expect that I should credit your bare assumption. It would be exceedingly difficult to believe without the most convincing proofs, which you have not brought forward. I prepared the case for the defence at the trial, and I only permitted that defence to be put forward because there was no other course--the evidence was so overwhelming, and Penreath's obstinate silence in the face of it pointed so conclusively to his guilt." "Nevertheless, you were wrong. The question is, are you going to help me undo that wrong?" "You have not yet proved to me that it is a wrong," quibbled the solicitor. "Mr. Oakham, let me make this quite clear to you," said the detective sternly. "I have sent for you out of courtesy, because, as I said before, I like to do things in a regular way. As you force me to speak plainly, there is another reason, which is that I did not wish to make you look small, or injure your professional reputation, by acting independently of you. It would be a bad advertisement for Oakham and Pendules if it got abroad--as it assuredly will if you persist in your attitude--that an innocent client of yours was almost sent to the gallows through your wrong defence at his trial. It is in your hands to prevent such a scandal from becoming public property. But if you are going to stand on professional etiquette it is just as well you should understand that I am quite prepared to act independently of you. I have sufficient influence to obtain an order from the governor of the gaol for an interview with the condemned man, and I shall do so. I have discovered sufficient additional evidence in this case to save Penreath, and I am going to save him, with or without your assistance. You have had your way--it was a wrong way. Now I am going to have my way. I only ask you to trust me for a few hours. After I have seen Penreath you are at liberty to accompany me to the chief constable, to whom I shall tell everything. That is my last word."
