"We can talk here, sir, and we don't know who may be listening to us in there. What do you suppose is in that box, Captain Barclay?"

"I give you my word, Allardyce, that I have no idea."

"Well, I can only find one theory which will fit all the facts. Look at the size of the box. Look at all the carving and metal-work which may conceal any number of holes. Look at the weight of it; it took four men to carry it. On the top of that, remember that two men have tried to open it, and both have come to their end through it. Now, sir, what can it mean except one thing?"

"You mean there is a man in it?"

"Of course there is a man in it. You know how it is in these South American States, sir. A man may be President one week and hunted like a dog the next. They are for ever flying for their lives. My idea is that there is some fellow in hiding there, who is armed and desperate, and who will fight to the death before he is taken."

"But his food and drink?"

"It's a roomy chest, sir, and he may have some provisions stowed away. As to his drink, he had a friend among the crew upon the brig who saw that he had what he needed."

"You think, then, that the label asking people not to open the box was simply written in his interest?"

"Yes, sir, that is my idea. Have you any other way of explaining the facts?"

I had to confess that I had not.
