Some weeks before, Jack, with a friend and confederate, Marlowe, formed a plan for entering a house on Madison Avenue, which, they had reason to believe, contained a considerable amount of plate. The owner was absent in Europe and the house was left during his absence under the care of Paul Hoffman and his mother. Paul, whose early history is recorded in “Paul, the Peddler,” was the proprietor of a street necktie stand, near the Astor House. He had on one occasion shown kindness to Julius, and the latter was grateful. Learning that Jack and Marlowe proposed to enter the house occupied by Paul, he showed his gratitude by giving the young street merchant an intimation of their intentions. Thus, when the attempt was made, Paul was prepared, and the two burglars walked into a trap. Jack was caught on the spot, but Marlowe for the time escaped. Had he left the city at once, he might have escaped wholly. But he was inflamed with bitter anger against the boy Julius, who, as he rightly judged, had betrayed them, and he was determined to be revenged. Following the boy to Staten Island, he overtook him in a lonely place, and but for timely interference might have murdered him, in which case the present volume would never have been written. But Julius was reserved for better things. His dangerous enemy was arrested, and being identified as having been concerned in the Madison Avenue robbery, was tried in due form, and sentenced to ten years’ imprisonment in Sing Sing. I have anticipated matters a little, as at the time the present story opens both he and Jack Morgan were temporarily confined in the Tombs, while awaiting trial. As for Julius, he was rewarded by a gift of fifty dollars, and, by the advice of his new friends, determined to seek a home in the West, going out under the auspices of the Children’s Aid Society. The company of which he was to be one was to start in a few days. Meanwhile Julius decided to enjoy a rest from his usual labors, having an ample supply of money to meet his small expenses. On the whole, he was pleased with the idea of going West. But, apart from this consideration, he felt that his life would not be safe in the city should Jack Morgan or Marlowe succeed in breaking jail, as they had done more than once before. The boy had good reason to apprehend danger, for he well knew their brutal natures, and their unscrupulousness, and that they would stop at no crime in wreaking vengeance upon him. Once out West, however, he would be out of their reach, and it was not likely that they would follow him out there. CHAPTER II. THE “GRAND DUKE’S OPREA HOUSE.”
