We were present the following morning at the examination of Renauld. Short as the time had been, I was shocked at the change that had taken place in the young prisoner. His cheeks had fallen in, there were deep black circles round his eyes, and he looked haggard and distraught, as one who had wooed sleep in vain for several nights. He betrayed no emotion at seeing us.  
The prisoner and his counsel, Maître Grosíer, were accommodated with chairs. A formidable guard with resplendent sabre stood before the door. The patient greffier sat at his desk. The examination began.
 
“Renauld,” began the , “do you deny that you were in Merlinville on the night of the crime?”
 
Jack did not reply at once, then he said with a hesitancy of manner which was piteous:
 
“I—I—told you that I was in Cherbourg.”
 
Maître Grosíer frowned and sighed. I realized at once that Jack Renauld was on conducting his own case as he wished, to the despair of his legal representative.
 
The magistrate turned sharply.
 
“Send in the station witnesses.”
 
In a moment or two the door opened to admit a man whom I recognized as being a porter at Merlinville station.
 
“You were on duty on the night of June 7th?”
 
“Yes, monsieur.”
 
“You witnessed the arrival of the 11:40 train?”
 
“Yes, monsieur.”
 
“Look at the prisoner. Do you recognize him as having been one of the passengers to alight?”
 
“Yes, Monsieur le juge.”
 
“There is no possibility of your being mistaken?”
 
“No, monsieur. I knew M. Jack Renauld well.”
 
“Nor of your being mistaken as to the date?”
 
“No, monsieur. Because it was the following morning, June 8th, that we heard of the murder.”
 
Another railway official was brought in, and confirmed the first one’s evidence. The magistrate looked at Jack Renauld.
 
“These men have identified you . What have you to say?”
 
Jack his shoulders.
 
“Nothing.”
 
M. Hautet exchanged a glance with the greffier, as the scratching of the latter’s pen recorded the answer.
 
“Renauld,” continued the magistrate, “do you recognize this?”
 
He took something from the table by his side, and held it out to the prisoner. I as I recognized the aeroplane .
 
“Pardon,” cried Maître Grosíer. “I demand to speak to my client before he answers that question.”
 
But Jack Renauld had no consideration for the feelings of the wretched Grosíer. He waved him aside, and replied quietly:
 
“Certainly I recognize it. It is a present given by me to my mother, as a souvenir of the War.”
 
“Is there, as far as you know, any duplicate of that dagger in existence?”
 
Again Maître Grosíer burst out, and again Jack him.
 
“Not that I know of. The setting was my own design.”
 
Even the magistrate almost at the boldness of the reply. It did, in very truth, seem as though Jack was rushing on his fate. I realized, of course, the vital necessity he was under of , for Bella’s sake, the fact that there was a duplicate dagger in the case. So long as there was supposed to be only one weapon, no suspicion was likely to attach to the girl who had had the second paper-knife in her possession. He was shielding the woman he had once loved—but at what a cost to himself! I began to realize the magnitude of the task I had so lightly set Poirot. It would not be easy to secure the acq............
