“‘I have seen him from where I was hidden under the bed in his state-room!’ replied the lad promptly; ‘and,’ continued the little fellow, ‘I can assure you, madame, beyond all question, he is the very man you are after.’
“‘What is the number of his state-room?’ inquired the black domino.
“Then the boy made an answer which I did not distinctly hear, as they both began to converse in a low, hurried tone. There is a stack of mattresses on the larboard side, and I was leaning against it, and they were on the other side. After a long, whispered conversation, they began to talk a little louder, and then I heard the boy say:
“‘I have found out all you wish to know about Napoleon, and you had better act promptly.’
“‘No, not yet,’ replied the black domino, ‘my plans are not ripe yet; but you must keep your eye on him until I am ready.’
“‘You may depend on me to do that,’ replied the lad; ‘he never shall leave this boat without your consent.’
“‘You are a splendid detective, and shall be abundantly rewarded for your faithful services.’
“‘I have already been rewarded,’ said the boy, ‘ten times more than I deserve. I would do anything to please you!’
“‘I thank my little friend, and mean to show my gratitude in a tangible shape one of these days. I am going to purchase a nice cottage for your mother if I ever get enough money.’
“‘You are too kind, miss; you have done more for me than I deserve; but I will serve you as long as I live. I hope you will succeed in bringing that bad man to punishment for his wicked crimes.’
