Bangs gave him his instructions and he went out of the office by the rear entrance. He saw De Forest in the alley, but as he had nothing to do with him, let him go. He went down Chestnut street, turned into Third, where the cars start from, and, as he had a few hours to spare, determined to see some of his old friends. He had been loafing around about an hour when one of the detectives of the city force stepped up to him, and, tapping him on the shoulder, said: "You are my prisoner." "What have I done to deserve arrest?" demanded Rivers, completely dumbfounded. "Never you mind that! you're my prisoner, and if you don't come along quietly, you'll pay for it!" was all the consolation he got from the detective. "But I haven't done anything," pleaded Rivers. "There, just shut up, now! I don't want any of your talk. I know my business, and you're my prisoner; so just you come along." Rivers, finding resistance useless, went with him. At the same time he saw De Forest looking on, and seeming to rather enjoy his predicament. As the detective was taking him up Chestnut street toward his headquarters, they passed the Adams Express Office. Bangs happened to step out at this moment, and was much amazed to see Rivers under arrest. They said nothing, but Rivers looked steadily at Bangs, and Bangs at him. Without a moment's reflection, Bangs rushed off to report the arrest of Rivers to me. I was holding a consultation with Madam Imbert and Miss Johnson, at the Merchants' Hotel. Everything was working well, and I felt particularly happy, when Bangs rushed in and dispelled my happiness by stating that Rivers had been arrested. At the news, my heart fairly jumped into my mouth. I had felt success almost within my grasp, and now my plans had fallen through entirely.
