"No!" Hockley shouted. "That won't be necessary. I know now—"

He almost laughed aloud to himself. This was an incredible piece of good luck. Waldon Thar was probably out at the space port right now—unless one of those ships taking off had been the Ryke—

He wondered why Thar had not tried to contact him. Of course, it had been a long time, but they had been very close at the center. He dialed the field control tower. "I want to know if the ship from Rykeman III has departed yet," he said.

"They were scheduled for six hours ago, but mechanical difficulty has delayed them. Present estimated take-off is 1100."

Almost two hours to go, Hockley thought. That should be time enough. "Please put me in communication with one of the aides aboard named Waldon Thar. This is Sherman Hockley of Scientific Services. Priority request."

"I'll try, sir." The tower operator manifested a sudden increase of respect. "One moment, please."

Hockley heard the buzz and switch clicks of communication circuits reaching for the ship. Then, in a moment, he heard the somewhat irritated but familiar voice of his old friend.

"Waldon Thar speaking," the voice said. "Who wishes to talk?"

"Listen, you old son of a cyclotron's maiden aunt!" said Hockley. "Who would want to talk on Sol III? Why didn't you give me a buzz when you landed? I just found out you were here."

"Sherm Hockley, of course," the voice said with distant, unperturbed tones. "This is indeed a surprise and a pleasure. To be honest, I had forgotten Earth was your home planet."
