"Johnny, this is important. I don't send Archie because he is needed here, and Saul is not available."
"Yes, sir. Shoot."
"The Michael Walsh whom you followed this morning has been released by the police because they don't know if he is the one they want. They have put a shadow on him, so it would be dangerous for you to pick him up even if you knew where to look. It is very important for Archie to get in touch with him. Since he is pretending to the police that he is not the man they seek, there is a strong probability that he will stick to the ordinary routine of his life; that is, that he will go to work this evening. But if he does that he will certainly be followed there and a detective will be covering the entrance all evening; therefore Archie could not enter that way to see him. I am covering all details so that you will know exactly what we want. Is it true that when a building project is boarded up, there is boarding where the construction adjoins the sidewalk but not on the other sides, where there are buildings? I would think so; at least it may be so sometimes. Very well, I wish to know by what means Archie can enter that building project at, say, seven o'clock this evening. Explore them all. I understand from Miss Fox, who was there last Thursday evening to talk with Mr. Walsh, that they have just started the steel framework.
"Miss Fox also tells me that Mr. Walsh goes to work at six o'clock. I want to know if he does so today. You can watch the entrance at that time, or you may perhaps have found another vantage point for observing him from inside. Use your judgment and your wit. Should you phone here, use code as far as possible. Be here by six-thirty with your report."
"Yes, sir." Johnny stood up. "If I have to sugar anybody around the other buildings in order to get through, I'll need some cash."
Wolfe nodded with some reserve. I got four fives from the safe and passed them over and Johnny tucked them in his vest. Then I took him to the hall and let him out.
