"I hope so," Julie said. "Well, we have to do something; we can't stay here."
"Take me to the hiding place, Julie," he begged; "we can work out something from there."
She looked at him briefly, considering the alternatives, her mind torn between affection for him and fear for the underground's safety. He knew she was recalling the many plans they had made for when all this was over, the legal matter of Helen, their home in a world where the air was free.
"If I stay here they will get me," he reasoned. "At least we have a chance the other way—if we hurry!"
In sudden determination, she said, "Come on, then."
She took him by the hand and led him deeper into the park. During the year he had been an unofficial member of the underground, supplying them with blueprints, he had never seen their headquarters, but he suspected it was close by, right under the noses of the authorities, and Julie did not disappoint him. She led him to a stone-block monument commemorating heroes of the Last War, and effortlessly pushed aside one of the blocks to reveal the darkness of a tunnel.
"Follow me," she directed and disappeared.
Arthur did, but first he dropped the silver disc a few feet away. When they were in the tunnel, Julie closed the entrance again and produced a flashlight. By its beams, they made their way downward.
They walked for perhaps a half-mile, when the tunnel broadened into what seemed a cavern. Their footsteps echoed from the opposite wall with a click-click-click, click-click-click.
"The old subway," Julie explained, her voice hollow, and Arthur nodded. With the coming of the helibus system many years ago, the subways had been discarded and their entrances sealed and checked periodically. Of course, they couldn't know about the monument entrance. At least, they hadn't, Arthur amended, thinking of the silver disc whose emanations could now be easily picked up by the robots.
