"I suppose I'm in serious trouble now," stubbornly answered Walter, "but I won't take back what I said. The _Juan Lopez_ has a lot of freight on board that doesn't belong there, and I intend to find out all about it." Captain Brincker leaned forward in his chair, his strong, brown hands resting upon his knees, his keen eyes almost mirthful. "You are frank with me," said he. "We are at cross-purposes, you and I. I give you my word of honor as a soldier that I know nothing whatever about this stolen freight. It is safe to tell you the truth, because I cannot let you go free until after the _Juan Lopez_ sails. I am not her captain. I am in charge of the expedition. There may be a change of government in San Salvador very soon. Perhaps I shall assist. The plans are in the hands of my employer, in whose house you have the honor to be." "Then it is a filibustering expedition," cried Walter, all interest and animation. "And you are going to mix up in another revolution? Whew, but I wish you would take me with you." "With your arm in a sling? Besides, my employer detests Americans. Do you believe I am telling the truth?" "It sounds that way," confessed Walter. "But what about that checker? He must be in the house right now." With a shrug, Captain Brincker explained: "He comes to see my employer. It is not my affair. I have had no words with the young man except this afternoon at the wharf. I was instructed to see that certain supplies were taken on board. I asked him about them. I did not look at the stuff. It was his business to check it up." It was quite obvious that Captain Brincker was anxious to clear himself in the eyes of this honest, ingenuous accuser. He may have committed many a greater crime against the law, but he disliked being thought a commonplace thief. Tempted by the amicable drift of the interview, Walter ventured a dangerous question: "Your employer--who is he?" Captain Brincker scowled. This was treading on forbidden ground. He may have been inwardly disgusted that the man he served should have stooped so low as to pilfer supplies for the expedition, but the matter was not for him to meddle with. He had an odd code of loyalty, a sadly twisted sense of honor, but such as they were he was stanch to them. He would not break with the man who had bought his sword and his services. "My employer?" said he. "That is not for me to tell you. I shall have to lock you up for the present. It would be most unfortunate to have the expedition of the _Juan Lopez_ spoiled by the tongue of a meddlesome boy. The American government would seize the ship and arrest all hands if the news leaked out. You know too much to be at liberty."
