During the whole conversation the man kept his improvised mask on, and made it clear that his motive in so doing was to prevent the possibility of his being made to appear in court to verify the statements he desired to communicate. He gave information mainly bearing on the conspiracy meeting which had been held on the evening of May 3, at No. 54 West Lake Street, and the interview lasted until about three o’clock.
When we parted I was no wiser as to his identity than I had been before, and to this day I don’t know with whom I talked there in my back yard that early morning.
In the forenoon of the 9th of May my trusted assistants again met in the office to compare notes. At this meeting I told Mr. Furthmann what a ghost I had seen that night, and in our deliberations that ghost aided us a great deal.
As a result the detectives started out with new instructions, and they were ordered to be back at the office at one o’clock in the afternoon. All reported promptly except a few who had struck a good trail and who kept out until six o’clock. The reports of those present showed good results. They started out again at two o’clock with new instructions and were ordered to report as soon as they had completed their work. Between three and five o’clock that afternoon things became exceedingly lively. The Anarchists began to move about like hornets disturbed in their nest, and some jumped around as if charged with electricity. Towards six o’clock the detectives reported back to the office, and an exchange of notes showed that it had been a day more fruitful of results than the day preceding. I found that a strong chain had been wrought connecting all the leading Anarchists in Chicago with the Haymarket murder, and I knew that no mistakes had been made in the arrest of those who had already been locked up.
During the same evening Mr. Grinnell and Mr. George Ingham gave me a call, and anxiously inquired about the progress made in the case. Mr. Grinnell assured Mr. Furthmann and myself that Mr. Ingham was all right, being with them, and with this statement all the facts were laid before them.
When the whole situation had been explained, Mr. Ingham said:
“Mr. Grinnell, now you have a case.”
“George,” replied Mr. Grinnell, “up to the time when Capt. Schaack began his work I had no case whatsoever. I would have been laughed out of court, but now I say we have a good, strong case, and it will be in excellent shape. The boys are making it stronger every day. They have got things down fine, and they are going to bring out everything there is in it.”
We worked that night until one o’clock, and met again the next morning at eight, vigorous and keen for further developments. At this time we had our hands full, with an abundance of material on which to work. During the night several letters were dropped in my letter-box, and they all contained good news. Some of the letters were somewhat obscure, their import having to be guessed at from suggestive circumstances, but they nevertheless helped. With fresh instructions the detectives started out for the day and reported back at one o’clock as per orders. Everything was discovered to have worked well. About two o’clock a man was noticed standing across the street from the station. His actions were somewhat strange, and one of the officers remarked that the fellow appeared to be watching the building very closely. I told the officer to keep watch of him, and in the event of his walking away to follow him. The man did not move, and as he remained there for nearly half an hour I ordered the officer to go across the street and ascertain what the stranger was watching. The man declined to speak at first, but, after the officer had threatened to lock him up, he stated that he desired to see me, but did not want to go into the building. He then requested the officer to tell me that he would meet me at the corner of La Salle and Chicago Avenues, and I was so notified.
I started at once to see the man, but as soon as he saw me he started off. When he got to the corner he turned north on La Salle Avenue, and I followed. When I got within twenty feet of him he looked around, and then dropped a letter, pointing his fingers to it as he passed on, without stopping. I picked up the letter and went back to the station. This letter contained very important matter and kept us busy for two days. This man was a stranger to me. I had never seen him before to my knowledge, and I have never seen him since.
