Torry had learned that at once last night.

But Grannar's return to the police car cut short his reverie. Torry watched the official cross the spaceport toward him, impressed by the lithe grace and sureness of movement over treacherous sand. Mars does something to a man who stays there. The body dries up and the soul withers, but if he survives, a man grows into something lean and leathery with pantherish strength and easy, poised motions.

Grannar vaulted to the driver's seat and slammed on power. With a skirl of steering runners, the half track took off toward the bubble city of New Chicago, named without tenderness by some long forgotten exile. Grannar drove with careless violence, but the half track skimmer shot among the dunes and low, lichen-clad hills without incident.

There is no truth to the charge that it takes as long to get from the spaceport to New Chicago as it does to reach Mars from Earth. But the distance is impressive and the going rough. Grannar talked as he drove, seeming casual, but his questioning had the same icy skill and unerring judgment.

"We'll start at the beginning," he said.

"There is no beginning," Torry jerked out angrily. "I got in last night. Fresh from the spaceport and customs, I put a coin in the public visiphone and asked Central Information about Roper. Central had no information and returned my coin. It was a police trap. Your men picked me up, searched me with a Geiger counter and found the coin. You keep faintly radioactive coins in the visiphone machines for Central to return when someone is curious about police business. It came out even. You found out I was curious about Roper, and I found out he is police business, and his case is current. Do you think I'd be fool enough to call such attention to myself if I knew about Roper's prison break?"

"You might be. And it might be smart. That way you'd find out what the police knew and what they were doing. And it could be an alibi in case the breakout was delayed. We'll skip those possibilities for now. You were mulish last night about certain questions. I'm still not clear about why you are so desperate to find Roper. Why?"

Torry smiled coldly. "That's easy. I have to find him for a legal release. Preferably dead, which will make things easier for everybody. But if he's alive, I want his signature and prints on some papers."

"Why? What papers?"

Torry hesitated. "It's a touchy subject. A personal matter. Nothing to do with the police."
