She stopped before a keyboard like the console of a gigantic organ. Behind it rose massed ranks of vacuum tubes, all glowing, humming, flickering. The girl's fingers skipped nimbly on the keys, and notes of sound rose in tinkling, chiming sprays from the shafts. Colors stormed and raged in the crystalline forest, running up and down the visible octaves of light. One sensed other scales beyond, in both upper and lower wavelengths. Glass panels and crystal shafts vibrated to sound and light, like tuning forks. They stirred, quivered, vanished, then reappeared. A tall man appeared among the shafts and strode toward the travellers. "Khaljean!" said Pao Chung nervously. It was sufficient introduction. There was uncanny resemblance between father and daughter, like two matched paintings in different keys. The animal man listened quietly, while Teucrete explained the situation. He looked at Pao Chung and laughed. He shrugged. "A bargain is a bargain," said Khaljean. "Perhaps I should go back to Venus and fabricate some gnawed bones to convince the police searching parties that the animals devoured you. All of you had better remain here and wait till I send for you." "You are good at faked evidence," Pao Chung jibed bitterly. "In a good cause, yes," agreed Khaljean good-naturedly. "Even in a bad cause, this time. Stay here. You will be safer." "Wait!" ordered Ferris. Khaljean measured him mockingly. "Who are you to say?" "I am a gamma-man," Ferris told him. "That doesn't frighten me, youngster. So am I. Or was. Do you know the name Djevos Barian?" Ferris blinked. "But Barian was hunted down and killed, his remains positively identified." Khaljean smiled. "As Pao Chung said, I am good at faked evidence. I always had a skill with synthetics. A man thing I created lived long enough to be slaughtered in my place, and I had constructed him well, even to duplicating my fingerprints and brain patterns. Officially I am dead. But ten years ago Pao Chung found out about me. He has bled me systematically ever since. Until now." "Shall I kill him for you?" asked Angel, with malicious joy in the thought. "Now that you have access to his evidence, his life can be only a menace to you." Khaljean frowned. "I don't believe in killing. But sometimes Pao Chung has tempted me. No, let him live." "So you are Barian?" said Ferris admiringly. "Was Barian. I have become Khaljean. The real one was a small-time operator, dealing chiefly in dead animals. I was with him when he died. We were much alike in appearance. With plastic surgery, I became Khaljean. And I have made the name famous. You must be one of the seven recent escapees from the reservation. We will have much to talk about later." "Not later," insisted Ferris. "Now. Where does this maze lead?"
