"Should I wait here?" the pilot asked.

"Yes," Walton said. With accession to the permanent directorship he rated a private ship and a live pilot. "I won't be here long."

"I'm Walton, director of Popeek. I have an appointment with Security Head Martinez."

A screen was set in the inner door.

Martinez' face confronted him.
