One officer, who proved of great assistance to me, was Charles Nordrum. He became engaged in the case shortly after the Haymarket riot, and after a time became a regular attaché of the detective department. He was born in Norway on the 9th of November, 1858, and had lived in Chicago since 1868. He joined the police force in November, 1884, and, possessing a great deal of tact and shrewdness, his services were soon enlisted in the work of hunting up the red conspirators. He worked at times with Officer Schuettler, but reported to Ebersold. Both were known to my officers, but they did not know of my private workers. Nordrum was especially detailed to look after some meetings at Thalia Hall, at the Emma Street Hall, in the rear room of Zepf’s saloon, in the rear room of Greif’s saloon, at No. 600 Blue Island Avenue, and at the Northwestern Hall, and he did not overlook meetings held in the cellars of some of the more prominent Anarchists on the Northwest Side and of others who were in sympathy with the Anarchists. He wormed himself into the good graces of quite a number of the reds, and was always kindly received by them. After a time the police stopped the holding of meetings in some of the halls, and then the Anarchist sympathizers harbored the reds in their cellars, furnishing candles for illumination and nail-kegs for seats. On the 5th of July, 1887, Nordrum was exposed at No. 599 Milwaukee Avenue, and he was at once surrounded by an infuriated mob. The Anarchists with whom he had associated attempted to kill him, but the officer, after a desperate fight, succeeded in reaching the door before any serious violence had been done him. This, of course, destroyed his further usefulness among them, but out of his knowledge of the men and their affairs two arrests were effected. He and Officer Schuettler brought in Emil Wende and Frederick Kost, members of the Terra Cotta Union. These men had been selected to buy each member of their group a 42-caliber revolver and one box of cartridges, and the weapons so secured were to have been used on the police on the day of the execution. The weapons had been purchased, and as soon as the principals had been placed under arrest, a descent was made upon the supply. All the revolvers were captured and brought to the Central Station. [Illustration: UNDERGROUND CONSPIRATORS.] Noticing how successfully they had been circumvented in all their movements, the Anarchists naturally came to the conclusion that detectives were working in their ranks either in the interest of myself or of Billy Pinkerton, and they resolved to discover, if possible, the men so engaged. One day a very intelligent fellow called at my office and wanted to know if I desired any more men to work for me among the Anarchists. He stated that he was well acquainted with all the reds, and, if I would pay him well, he would render good service.
