Frank thanked him, and putting the pass carefully away in his pocket, walked out of the hotel fully satisfied on one point, and that was, if his success depended upon the good wishes of his friends, failure was impossible. He walked slowly down the street toward the place where the soldiers were encamped; for as it lacked fully an hour and a half of the appointed time, he did not wish to be seen loitering about the house, as it might excite the suspicions of its inmates, who would not fail to send word to Mr. Abbott that the house was being watched. Time moved altogether too slowly for the impatient young officer, but at length he heard the flag-ship's bell strike half-past seven, and as it had begun to grow dark, he walked toward the house, and took his station in the shadow of some trees on the opposite side of the street. At the end of an hour his patience was rewarded, for he heard the sound of approaching footsteps, and a man passed by the house. Frank knew, from the suspicious manner in which he gazed about, that if it was not the man for whom he was waiting, it was some other guilty fellow who ought to be secured. Presently he returned, and after again looking cautiously about him, ascended the steps and knocked lightly at the door, which was almost instantly opened, and a voice exclaimed: "Massa Abbott, I'se glad to"-- The rest of the sentence Frank did not hear, for the moment the man entered the hall, the door was closed again. Now was the time for Frank, who hastily crossed the street, and noiselessly ascended the steps. Here he paused for a moment to draw his revolver, and then suddenly opened the door and sprang into the hall. He was met by the negro, the same, no doubt, whom he had heard welcoming his master, who, not liking the looks of the huge six-shooter which the officer flourished before his eyes, beat a hasty retreat. Frank kept on and entered the parlor, where he found his man standing in the middle of the floor, pale and breathless. No one else was in the room. "Mr. Abbott," said Frank, "you're my prisoner!" The man, who was so terrified that he seemed to have lost even the power of speech, surrendered his weapons and submitted to his captor, who led him out of the house and toward the flag-ship, which they reached in safety. The admiral received Frank with great cordiality, and after listening to his account of the manner in which the capture of the prisoner had been effected, he ordered the cutter called away, and the young officer, rejoicing over his success, was sent on board his vessel.
