‘By Jove! sir, I see it now. He got a sheet of paper and an envelope to write to Mr. Avery. He left the envelope and vanished with the sheet.’
‘Of course. It occurred to me when Mr. Avery told me of the empty envelope. I guessed what he was going to do, and therefore I hurried to the docks in the hope of being before him. And now about that label on the cask. You might describe it again as fully as you can.’
‘It was a card about six inches long by four high, fastened on by tacks all round the edge. Along the top was Dupierre’s name and advertisement, and in the bottom right-hand corner was a space about three inches by two for the address. There was a thick, black line round this space, and the card had been cut along this line so as to remove the enclosed portion and leave a hole three inches by two. The hole had been filled by pasting a sheet of paper or card behind the label. Felix’s address was therefore written on this paper, and not on the original card.’
‘A curious arrangement. How do you explain it?’
‘I thought perhaps Dupierre’s people had temporarily run out of labels and were making an old one do again.’
Burnley replied absently, as he turned the matter over in his mind. The clerk’s suggestion was of course possible, in fact, if the cask really contained a statue, it was the likely one. On the other hand, if it held a body, he imagined the reason was further to seek. In this case he thought it improbable that the cask had come from Dupierre’s at all and, if not, what had happened? A possible explanation occurred to him. Suppose some unknown person had received a statue from Dupierre’s in the cask and, before returning the latter, had committed a murder. Suppose he wanted to get rid of the body by sending it somewhere in the cask. What would he do with the label? Why, what had been done. He would wish to retain Dupierre’s printed matter in order to facilitate the passage of the cask through the Customs, but he would have to change the written address. The Inspector could think of no better way of doing this than by the alteration that had been made. He turned again to his visitors. ‘Well gentlemen, I’m greatly obliged to you for your prompt call and information, and if you will give me your addresses, I think that is all we can do to-night.’
Inspector Burnley again made his way home. But it was not his lucky night. About half-past nine he was again sent for from the Yard. Some one wanted to speak to him urgently on the telephone.
