Tickler left and Spence dashed to his quarters and began stuffing his belongings into a travel frame, the soft-sided, collapsible carrier of lightweight design used exclusively for shuttle travelers. They were a status symbol back on Earth, identifying seasoned jumpvets. Naturally, they were copied by numerous manufacturers and sold to anyone who wanted one badly enough to pay the outrageous sums these frames fetched. His own bore the company logo in silver on the side and had been given to him prior to the jump.

Although allowed to take two frames with him on the trip, he decided to squeeze by with one. He did not care to be bothered with unnecessary baggage. Only at the last minute did he decide to take along his camera.

When it was ready he called housekeeping and asked them to send someone to take it down to the docking bay for him. He did not wish to be seen lugging his frame through the station; he had played it close this far and did not want to risk giving himself away so near to the payoff.

Within the hour a page came to take his frame down for him. "Do you know who I am?" Spence asked the young man. "No, sir." He acted as if it was a question he heard often. "I'd appreciate it if no one else knew either. If anyone asks, you never saw me and the frame belongs to Dr. Packer. Got that?" "Got it."

Spence handed him a stack of coins for his trouble. "Here, have one of whatever it is you guys have these days on me." "I never saw you, sir."

"Right."

The kid disappeared pulling the frame through the portal.

Spence went back to his quarters and carefully arranged everything to appear as if he had only stepped from the room and would be returning any moment. Why he went to the trouble he did not know. And he told himself that he was being ridiculous. But having adopted the undercover posture he found himself enjoying the intrigue.

He left the jumpsuit he had been wearing the night before hanging over the chair. Scattered papers lay on his desk, and a mug of cold coffee sat on the table beside the bed. The bedclothes themselves he left rumpled.

When at last he had satisfied himself that everything looked normal, he tiptoed out and left the lab. He had no sooner crossed the threshold of the portal than he ran smack into his assistant, Kurt Millen.

"Kurt!" he gasped, nearly knocking the young man over.

"Excuse me, Dr. Reston, I didn't see you coming. We're always bumping into one another."

"Yes-" Spence's mind raced to think of a way to escape without arousing suspicion. "I… I was just on my way to the commissary. Would you like to join me?"

For one sickening second he thought the cadet would accept his bogus offer.

"Thank you for inviting me, Dr. Reston. But I've got some things to do-Dr. Tickler left me a list of chores. I'd better not."

"You're sure? Just a cup of coffee? I'll buy." Spence fearlessly played the charade to the ragged edge.

"Maybe some other time?"

"Sure-no problem. I won't be a minute." He turned and started away. "I'd better go grab a place in line so I can get back."

He left the cadet standing in front of the lab entrance watching him. Spence kicked himself for overacting his part. He had quite possibly created suspicion where no suspicion existed before. So, to make it look good he strolled dutifully along to the commissary and went inside to stand in line for a few minutes.

He then left, darting back into the trafficway and losing himself in the between-shift throngs heading to and from the cafeteria. He suspected that Kurt would try to follow him. He told himself the notion was absurd, but dodged into a tube and changed levels a couple times anyway, arriving at Ari's door glancing over his shoulder and peering into every shadow.

"Spence! Oh, I'm so glad you came. I was afraid something had happened."

"Something almost did. But there's no problem now." He stepped quickly inside and came to stand in the middle of the room with Ari. They stood face to face, both pretending to be coolly friendly and neither one succeeding. "How long can you stay?"

"Just a few minutes. I should get down to the bay before the others start boarding-just in case."

"I understand."

"Ari, I wonder if you could do me a favor while I'm gone?" said Spence suddenly.

"Of course, anything."

"My dad's birthday… I got him a souvenir, but I forgot to send it. Could you make sure he gets it? I left it in my jumpsuit in my quarters."

"I'll take care of it right away, Spence. Don't give it another thought."

Delicate silence followed this exchange. Ari looked at her hands, clasping them and unclasping them. Spence watched her as if she were practicing magic.

Finally, she raised her head shyly. "I'll miss you, Spence. I miss you already and you're not even gone."

"I'll miss you, too. I've been thinking that-"

Suddenly she was very close and his arms were around her, pressing her to him. She murmured softly and he smelled the fresh, clean scent of perfume in her hair.

"Spence, you'll be gone so long..,"

"Not so long. It'll pass quickly. You'll see." The words came out in a rush, and it was all he could do to keep his composure.

Why this turmoil, this confusion over a mere girl? What's come over me, he thought to himself.

"Well, I'd better go," he said at last. He was beginning to fear that if he stayed with her any longer he would not be able to leave.

She released him and composed herself, putting on a cheery face and manner.

"I'll think about you every day."

She took him by the arm and led him to the door. "You run along now. I know you're going to have a beautiful time of it-running around in your little space suits all of you, playing scientist."

"I'll come back and tell you all about it." He laughed and his voice made a hollow sound.

"I planned to go down to the bay with you, but I won't. I don't want you to see me cry."

He turned her face to his and kissed her gently. "Good-bye, Ari," he whispered, and then darted away. She heard his footsteps in the corridor and listened until they merged with other sounds. Then she went back to begin her wait. …

THE DOCKING BAY HUMMED with activity. The boarding tube had been attached to the transport which bore the name Gyrfalcon in glittering gold letters across her bulging bow. Skids of supplies and baggage-most of it scientific instruments in cargo frames-were being shoved aboard. Outside the station a small army of maintenance men swarmed the surface of the transport, their arc lights playing over the sleek, black skin of the ship as they moved through their preflight check. It looked like a great black whale patiently enduring a precise grooming by a platoon of tiny silver fishes.

On the big chronometer above the boarding tube he saw that there was less than an hour to blast time. A few of the younger cadet passengers were standing around the bay looking jittery and laughing loudly. Spence allowed himself only a few seconds more to take in the rush of activity around the great spaceship. Then he slipped in behind a roboskid loaded with dehydrated rations and entered the boarding tube feeling like a stowaway, half expecting someone to challenge him with a "Halt! Who goes there?"

No one did. No one seemed to notice his arrival at all, which produced a peculiar sense of disappointment for Spence.

He reached the end of the brightly lit tube and entered the hold where dozens of men labored to position all the stores and baggage and lock them into place within huge cargo frames. He threaded his way through the confusion and started toward the head of the ship and the passenger quarters.

A few yellow-suited maintenance men moved along the ship's central gangways trailing black-and-green striped hoses and wagons with odd-looking metallic boxes with flashing lights which emitted chirps and clicks as they slid along the floorplates. Spence also saw the royal blue jumpsuits of the transport's crew, who were standing at their stations or talking quietly to one another as the yellowsuits fiddled efficiently around them.
