At the bottom of the flight of narrow wooden steps there was a third security man. He greeted Joe.
"Major Holt told me to pick you up," he observed.
Joe walked to one side with him. Major Holt had promised to send a first-class man to meet Joe at this place, with orders to take instructions from Joe. Joe said curtly: "You're to snag as many Security men as you can, place them more or less out of sight under the Platform here, and tell them to turn off their walkie-talkies and wait. No matter what happens, they're to wait right here until they're needed, right here!"
He looked harassedly around him. The Security man nodded and moved casually away. This was close timing. Something made Joe look up. He saw the catwalk gallery nearly overhead. The expected guard was there. Haney, though, was with him. There was nothing else in sight. Not yet. But Haney was on the job. Joe saw a Security man step out of sight in the scaffolding. He saw his own assigned security man speak to another, who wandered casually toward the Platform's base.
Minutes passed. Only Joe could have noticed, because he was watching for it. There were eight or nine Security men posted within call. They had their walkie-talkies turned off and would be subject only to his orders if an emergency arose.
Gongs began to ring all around the edge of the Shed. They set up a horrendous clanging. This was not an alarm, but simply the notice of change-of-shift time.
There was a marked change in the noises overhead. A crane pulled back. Hammerings dwindled and stopped. There were the sounds of pipes, combined to form the scaffolds, being taken apart for removal. A sling-load of pipe touched the floor and stayed there. The crane's internal-combustion motor stopped. Its operator stepped down to the floor and headed for the exit. Hoists descended and men moved across the floor. Other men scrambled down ladders. The floor became dotted with figures moving toward the doors through which men went out to get on the busses for Bootstrap.
Nothing happened. More long minutes passed. The shift brought out by the busses was going through the check-over process in the incoming screen room. Joe knew that Major Holt had, within the past five minutes, gathered together a tight-knit bunch of armed security men to be available for anything that might turn up. The men doing the normal shift-change screening were shorthanded in consequence.
