With the information so far secured I became confident that I had an opening to the case, but, knowing that no aid could be had from the Central Headquarters, I refrained, I think wisely, from asking for assistance. In Mr. Grinnell and his staff, however, I had every confidence, and I went to his office. I told him what discoveries had been made, giving him all the details, and said to him that in working up the case I should frequently need his advice. He promptly said: “Schaack, you can command my services and those of every man in my office at any time.” I thanked him, and felt greatly strengthened in the task I had before me. Mr. Furthmann was directed to go with me and assist in the same way that he had assisted in working up the evidence in the Mulkowsky murder case. I then felt highly gratified, and stronger and more resolute than ever, because of my new partner in the case. When we were about to go, Mr. Grinnell said, “I will be up to-night and see you.” He called, as promised. We then told him what progress we had made during the day, and he expressed himself as greatly pleased. He urged us to keep everything as secret as possible and not to take any more people into our confidence than was absolutely necessary. Having given us this advice, he left us, but we continued our work until three o’clock the next morning. We met again—Furthmann and myself—the next day at nine o’clock, and that day we worked with great success. The boys brought us in good news every hour. Good citizens would leave letters at my house, and these would be immediately sent to me by my wife. Before eight o’clock that night we had gained an entrance to the conspiracy plot. Mr. Grinnell was sent for, and he called on us at once. He was informed of all the facts and said: “You boys have done well. You have found the missing link, and you have it right.” Mr. Grinnell became enthusiastic over the work accomplished and recognized the fact that the right parties were under arrest, and that what had been morally certain before as to a conspiracy had now been made a legal certainty susceptible of the strongest proof. In reaching this point, a great deal of work had been done, and in its performance talent, tact and ingenuity of a very high order seemed essential. Mr. Grinnell inspired us with confidence, however, and was kind enough to say, just before going home that night: “Schaack, I want to say that you are one of the greatest detectives in America.”
