The sun had almost set, when figures entered the underpass from each end. At one end Joe could see a silhouette of tall man, at the other a shorter man carrying a stick. He tightened his grip on his cane and waited for them to get to him. Before they arrived an access cover shifted in front of him and a youngster with blue hair climbed out. She was followed by another young woman, who looked at him suspiciously.
"Leave your cane against the wall," she ordered. "Jimmy brought one for you without the implements of torture embedded in it." Joe did as he was told. The blue-haired child raised his cane and examined it speculatively. If the lab was right she was over fifty, but she looked ten at the most.
"Let's go," the second girl waved at the access tunnel. "Do you need help?"
"I think I can manage," Joe replied. "The control for the cane is on the brass ring. It is biometrically matched to me, so others can't use it, but I don't know what would happen if you try to break into it."
