The man who entered the room was a striking figure. Very tall, with a well knit frame, and a deeply bronzed face and neck, he dominated the assembly. Even Giraud seemed anaemic beside him. When I knew him better I realized that Gabriel Stonor was quite an unusual personality. English by birth, he had knocked about all over the world. He had shot big game in Africa, travelled in Korea, in California, and traded in the South Sea Islands. He had been secretary to a New York railway magnate, and had spent a year encamped in the desert with a friendly tribe of Arabs.  
His unerring eye picked out M. Hautet.
 
“The examining in charge of the case? Pleased to meet you, M. le juge. This is a terrible business. How’s Mrs. Renauld? Is she bearing up fairly well? It must have been an awful shock to her.”
 
“Terrible, terrible,” said M. Hautet. “Permit me to introduce M. Bex—our commissary of police, M. Giraud of the Sûreté. This gentleman is M. Hercule Poirot. M. Renauld sent for him, but he arrived too late to do anything to the tragedy. A friend of M. Poirot’s, Captain Hastings.”
 
Stonor looked at Poirot with some interest.
 
“Sent for you, did he?”
 
“You did not know, then, that M. Renauld calling in a detective?” interposed M. Bex.
 
“No, I didn’t. But it doesn’t surprise me a bit.”
 
“Why?”
 
“Because the old man was ! I don’t know what it was all about. He didn’t in me. We weren’t on those terms. But rattled he was—and badly!”
 
“H’m!” said M. Hautet. “But you have no notion of the cause?”
 
“That’s what I said, sir.”
 
“You will pardon me, M. Stonor, but we must begin with a few formalities. Your name?”
 
“Gabriel Stonor.”
 
“How long ago was it that you became secretary to M. Renauld?”
 
“About two years ago, when he first arrived from South America. I met him through a friend, and he offered me the post. A thundering good boss he was too.”
 
“Did he talk to you much about his life in South America?”
 
“Yes, a good bit.”
 
“Do you know if he was ever in Santiago?”
 
“Several times, I believe.”
 
“He never mentioned any special incident that occurred there—anything that might have provoked some against him?”
 
“Never.”
 
“Did he speak of any secret that he had acquired whilst sojourning there?”
 
“No.”
 
“Did he ever say anything at all about a secret?”
 
“Not that I can remember. But, for all that, there was a mystery about him. I’ve never heard him speak of his boyhood for instance, or of any incident prior to his arrival in South America. He was a French Canadian by birth, I believe, but I’ve never heard him speak of his life in Canada. He could shut up like a if he liked.”
 
“So, as far as you know, he had no enemies, and you can give us no clue as to any secret to obtain possession of which he might have been murdered?”
 
“That’s so.”
 
“M. Stonor, have you ever heard the name of Duveen in connection with M. Renauld?”
 
“Duveen. Duveen.” He tried the name over thoughtfully. “I don’t think I have. And yet it seems familiar.”
 
“Do you know a lady, a friend of M. Renauld’s whose name is Bella?”
 
Again Mr. Stonor shook his head.
 
“Bella Duveen? Is that the full name? It’s curious! I’m sure I know it. But for the moment I can’t remember in what connection.”
 
The magistrate coughed.
 
“You understand, M. Stonor—the case is like this. There must be no reservations. You might, perhaps, through a feeling of consideration for Madame Renauld—for whom, I gather, you have a great and affection, you might—enfin!” said M. Hautet getting rather tied up in his sentence, “there must absolutely be no reservations.”
 
Stonor stared at him, a dawning light of comprehension in his eyes.
 
“I don’t quite get you,” he said gently. “Where does Mrs. Renauld come in? I’ve an immense respect and affection for that lady; she’s a very wonderful and unusual type, but I don’t quite see how my reservations, or otherwise, could affect her?”
 
“Not if this Bella Duveen should prove to have been something more than a friend to her husband?”
 
“Ah!” said Stonor. “I get you now. But I’ll bet my bottom dollar that you’re wrong. The old man never so much as looked at a petticoat. He just adored his own wife. They were the most couple I know.”
 
M. Hautet shook his head gently.
 
“M. Stonor, we hold absolute proof—a love letter written by this Bella to M. Renauld, accusing him of having tired of her. Moreover, we have further proof that, at the time of his death, he was carrying on an with a Frenchwoman, a Madame Daubreuil, who rents the adjoining . And this is the man who, according to you, never looked at a petticoat!”
 
The secretary’s eyes narrowed.
 
“Hold on, M. le juge. You’re barking up the wrong tree. I knew Paul Renauld. What you’ve just been saying is impossible. There’s some other explanation.”
 
The magistrate his shoulders.
 
“What other explanation could there be?”
 
“What leads you to think it was a love affair?”
 
“Madame Daubreuil was in the habit of visiting him here in the evenings. Also, since M. Renauld came to the Villa Geneviève, Madame Daubreuil has paid large sums of money into the bank in notes. In all, the amount totals four thousand pounds of............
