“I’ll throw that one and you can throw the other, Carbone,” Abarno said. “Now listen. We will meet here Tuesday morning at six o’clock to the minute. We will get to the Cathedral just at 6.20. Then we’ll light the bombs, and the fuses will burn slow for twenty minutes, so as we can get over to the Madison Avenue car and then we can all get to work on time, and we will have a good alibi all right. Then we’ll get together Tuesday night and go some place and have a good time to celebrate throwing a scare into Fifth Avenue, boys! Tuesday morning, six o’clock sharp?” Carbone and Polignani assented, and Abarno left. Polignani kept in close touch with me from that moment forward. Ever since the day when Carbone had sent him to the drug store for black antimony, with instructions to bribe the drug clerk if he could not easily obtain it, we had had a double check on the conspirators, for I had assigned two men to shadow them constantly. The case was building towards a climax. Polignani had shrewdly kept the slip on which Carbone wrote the prescription for the explosives, and when Carbone asked where it was he said, “I tore it up. I didn’t want it to be found on me. It would get me into trouble.” The anarchist praised the detective for his forethought. The two men from the Bomb Squad never let Abarno and Carbone out of their sight, so that for a month we had not only the direct evidence of Polignani of what the conspirators said and did in his presence, but evidence from the two shadows which accounted for their time more fully, probably, than they could have recalled themselves. And so when Polignani--who did not know he was being observed--told me of the final plans, I passed the information on to the two shadows, and we formulated a counter-campaign for Tuesday morning. Shortly after sunrise on Tuesday, Polignani tumbled out of bed and into his clothes. He ate a hasty and nervous breakfast at a cheap lunch-room around the corner, and hurried to the sidewalk before 1341 Third Avenue, arriving a few minutes after six. Abarno joined him at 6.30. “Where’s Carbone--isn’t he here?” he said by way of greeting. “No,” replied “Baldo.” “Well, we can’t wait for him. We can’t lose any time. I got to be at work at 7.30. Come up and get the bombs with me. We’ll probably meet him on the way down the street. Or maybe he’s at the shoe-shop.” The two men went upstairs and into the third-floor-back. “Give me the key,” Abarno muttered. Polignani did so. Abarno opened the trunk and took out the two bombs. “You take one and I’ll take the other,” he whispered. “Come on. Put it under your coat.”
