 			<p>“I also have had some news,” said <abbr>M.</abbr> Chauvet, when he had heard Burnley’s and Lefarge’s reports. “I sent a man up to that pump manufactory and he found out enough to substantiate entirely Boirac’s statement of the hours at which he arrived there and left on the night of the accident. There is also a despatch from Scotland Yard. On receipt of <abbr epub:type="z3998:name-title">Mr.</abbr> Burnley’s wire immediate inquiries were made about the cask sent by Havre and Southampton. It appears it arrived all right at Waterloo on the morning after it was despatched from here. It was booked through, as you know, to an address near Tottenham Court Road, and the railway people would in the ordinary course have delivered it by one of their lorries. But just as it was being removed from the van of the train, a man stepped forward and claimed it, saying he was the consignee, that he wished to take it to another address, and that he had a cart and man there for the purpose. He was a man of about medium height, with dark hair and beard, and the clerk thought he was a foreigner, probably French. He gave his name as Léon Felix and produced several envelopes addressed to himself at the Tottenham Court Road address as identification. He signed for, and was handed over the cask, and took it away. His movements after that were completely lost sight of, and no further traces of him have been discovered. A photo of Felix was shown to the Waterloo people, but while the clerk said it was like the man, neither he nor any of the others would swear to it.</p>
 			<p>“Inquiries have also been made about Felix. It turns out he is an artist or designer in <abbr epub:type="z3998:name-title">Messrs.</abbr> Greer and Hood’s, the advertisement and poster people of Fleet Street. He is not married, but keeps an elderly servant-housekeeper. This woman was on a fortnight’s holiday from the 25th of March to the 8th of this month.</p>
 			<p>“So much for London,” continued <abbr>M.</abbr> Chauvet. “Now, let us see what we have still to do. First, that lady’s maid at Dijon must be interviewed. I think, Lefarge, you might do that. Tomorrow is Sunday. Suppose you go tomorrow. You can sleep at Dijon, and get back as early as possible on Monday. Then, <abbr epub:type="z3998:name-title">Mr.</abbr> Burnley, that matter of the statue sent to <abbr>M.</abbr> Boirac must be gone into. Perhaps you would be good enough to make inquiries at Dupierre’s on Monday morning, and please keep in touch with me by phone. I will look into some other points, and we shall meet here at the same time that evening.”</p>

 			<p>On Monday morning Burnley called to see <abbr>M.</abbr> Thomas at the showroom in the Boulevard des Capucines.</p>
 			<p>“I’m back again, <abbr>M.</abbr> Thomas,” he said, as they greeted one another. He explained what had been learned about the casks at the Gare <abbr>St.</abbr> Lazare, continuing, “So you see, two must have been sent out. Now, can you give me any information about the sending out of the second cask?”</p>
 			<p>“Absolutely none, monsieur,” returned Thomas, who was evidently amazed at this new development, “I am quite positive we only sent one.”</p>
