‘That is quite clear, thank you,’ said La Touche.

‘I met the cask in London and brought it to the shed,’ went on the manufacturer. ‘There, after dismissing the carter, I opened the cask, took out the statue, packed it in a portmanteau I had with me, took the label off the cask and put it carefully in my pocket, replacing it with one addressed to Jacques de Belleville at the Gare du Nord. As you know, this Jacques de Belleville was myself.

‘As you found Dubois, the carter, you will have learnt the method by which I exchanged the casks, sending that containing the body from my house to Felix, while the other, which I had emptied in London, went back to Dupierre. You understand that part of it?’

‘Perfectly.’

‘So much then for the getting of the body to Felix. But it was my desire not only to give him the shock of opening the cask and discovering it; I wished also to make the police suspicious so that he would be watched and his attempts to get rid of the corpse discovered. In this case I intended he should be charged with the murder, incidentally clearing me. To ensure this result I set myself to construct such evidence as would weave a net round him from which he would be unable to escape. Gradually the details of my plan arranged themselves in my mind.

‘Firstly, it was necessary that I should really have the letter of farewell, the envelope of which I had prepared, and which I had pretended to find on going to my study. Collecting a number of specimens of my wife’s handwriting from her davenport, I forged the letter I showed to the French police. Putting it away for future use, I burnt the specimens to prevent them from being compared with the forgery.

‘The problem of getting Felix to meet the cask which I intended to send him, and while doing so to attract the attention of the police, then occupied my thoughts. After much consideration I decided on the plan you know. It happened that some three weeks previously I had been seated in the Café Toisson d’Or, when a bad neuralgic headache had come on, and I had moved into an alcove to be as private as possible. While there I had seen Felix come in and begin talking to a group of men. I had not made myself known, as I was in considerable pain, but I had overheard their conversation and learnt the arrangement Felix and his friend Le Gautier had made about the lottery. This I now decided to use, and I drafted a letter to Felix purporting to come from Le Gautier, mentioning this matter of the lottery to make it seem genuine. I also drafted a slip about money I intended to send in the cask. The contents of this letter and slip you know. These I put away in my pocket-book, to be used later.

‘The next evening, Monday, I pretended to unpack the cask. I brought the group I had taken out of it on the previous Saturday from the portmanteau in which I had hidden it, and placed it on the table in my study. On the floor, about the cask, I sprinkled some of the sawdust from the handbag. By this manœuvre I hoped if suspicion arose it would be argued that as the cask was not unpacked till Monday night, the body could not have been put into it on the night of the dinner. As you know, this ruse also succeeded. I also took the label off the cask and put it in my pocket.

‘Opening the cask again, I put in £52 10s. in English gold, to correspond with my slip. I hoped that, if the police got hold of the cask, they would assume that Felix had put in this money in order to strengthen his story that the cask had been sent to him. I put in sovereigns instead of French gold with the intention of making this theory more likely, as I hoped it would be argued that Felix in his agitation had overreached himself, and forgotten from what country the cask was supposed to be coming.

‘Calling François, I told him I had unpacked the statue, and when Messrs. Dupierre sent for the cask he was to give it to them. Then, informing him that I would be from home for a couple of nights, I left next morning by the early train for London.
