It was typewritten on rather thin, matt surfaced paper and, though Burnley was not an expert, he believed the type was foreign. Some signs of wear were present which he thought might identify the typewriter. The n’s and the r’s were leaning slightly to the right, the t’s and the e’s were below alignment, and the l’s had lost the horizontal bar at the top of the down-stroke. He held the paper up to the light. The watermark was somewhat obscured by the type, but after a time he made it out. It was undoubtedly French paper. This, of course, would not weigh much, as Felix by his own statement, was frequently in Paris, but still it did weigh. The Inspector read the letter again. It was divided into four paragraphs and he pondered each in turn. The first was about the lottery. He did not know much about French lotteries, but the statements made could at least be verified. With the help of the French police it would be easy to find out if any drawings and payments had recently been made, and he could surely get a list of the winners. A winner of 50,000 francs, living in or near Paris, should be easily traced. The second and third paragraphs were about the bet and the sending of the cask. Burnley turned the details over in his mind. Was the whole story a likely one? It certainly did not strike him as such. Even if such an unusual bet had been made, the test was an extremely poor one. He could hardly believe that a man who could invent the plan of the cask would not have done better. And yet it was undoubtedly possible. Another idea entered the Inspector’s mind. He had, perhaps, been thinking too much of the £988, and too little of the woman’s hand. Suppose there really was a corpse in the cask. What then? Such an assumption made all the circumstances more serious and explained partly the sending of the cask, but it did not, so far as the Inspector could see, throw light on the method of doing so. But when he came to the fourth paragraph he saw that it might easily bear two meanings. He read it again:-- ‘I send you my best congratulations on the greatness of your coup, of which the visible evidence goes to you in the cask, and my only regret is that I shall be unable to be present to see you open it.’ This seemed at first sight obviously to mean congratulations on winning the lottery, the ‘visible evidence’ of which, namely £988 in gold, was in the cask. But did it really mean this? Did a more sinister interpretation not also offer itself? Suppose the body was the ‘visible evidence’? Suppose the death was the result, possibly indirect, of something that Felix had done. If money only was being sent, why should Le Gautier experience regret that he could not see the cask opened? But if a corpse was unexpectedly hidden there, would not that statement be clarified? It certainly looked so. One thing at least seemed clear. If a corpse had been sent to Felix, he must know something of the circumstances leading up to it. The Inspector spoke again:--
