Because Davies thought this would be exactly the kind of message an alien intelligence might send, he figured it would be easy for the SETI people to figure out. He distributed his picture to everybody at the conference.
Nobody could figure it out.
When Davies explained it, they all agreed it was a clever idea, and a perfect message for extraterrestrials to send. But the fact remained that none of them had been able to figure out this perfect message.
One of the people who had tried to figure it out, and had failed, was Ted.
"Well, we didn't try very hard," Ted said. "There was a lot going on at the conference. And we didn't have you there, Harry."
"You just wanted a free trip to Rome," Harry said.
Beth said, "Is it my imagination, or have the door markingschanged?"
Norman looked. At first glance, the deep grooves appeared the same, but perhaps the pattern was different. If so, the change was subtle.
"We can compare it with old videotapes," Barnes said. "It looks the same to me," Ted said. "Anyway, it's metal. I doubt it could change."
"What we call metal is just a liquid that flows slowly at room temperature," Harry said. "It's possible that this metal is changing."
"I doubt it," Ted said.
Barnes said, "You guys are supposed to be the experts. We know this thing can open. It's been open already. How do we get it open again?"
"We're trying, Hal."
"It doesn't look like you're doing anything."
From time to time, they glanced at Harry, but Harry just stood there, looking at the sphere, his hand on his chin, tapping his lower lip thoughtfully with his finger.
"Harry?"
Harry said nothing.
Ted went up and slapped the sphere with the flat of his hand. It made a dull sound, but nothing happened. Ted pounded the sphere with his fist; then he winced and rubbed his hand.
"I don't think we can force our way in. I think it has to let you in," Norman said. Nobody said anything after that. "My hand-picked, crack team," Barnes said, needling them. "And all they can do is stand around and stare at it."
"What do you want us to do, Hal? Nuke it?"
"If you don't get it open, there are people who will try that, eventually." He glanced at his watch. "Meanwhile, you got any other bright ideas?"
Nobody did.
"Okay," Barnes said. "Our time is up. Let's go back to the habitat and get ready to be ferried to the surface."
DEPARTURE
Norman pulled the small navy-issue bag from beneath his bunk in C Cylinder. He got his shaving kit from the bathroom, found his notebook and his extra pair of socks, and zipped the bag shut.
"I'm ready."
"Me, too," Ted said. Ted was unhappy; he didn't want to leave. "I guess we can't delay it any longer. The weather's getting worse. They've got all the divers out from DH-7, and now there's only us."
Norman smiled at the prospect of being on the surface again. I never thought I'd look forward to seeing Navy battleship gray on a ship, but I do.
"Where're the others?" Norman said.
"Beth's already packed. I think she's with Barnes in communication. Harry, too, I guess." Ted plucked at his jumpsuit. "I'll tell you one thing, I'll be glad to see the last of this suit.
They left the sleeping quarters, heading down to communications. On the way, they squeezed past Teeny Fletcher, who was going toward B Cylinder.
"Ready to leave?" Norman said.
"Yes, sir, all squared away," Fletcher said, but her features were tense, and she seemed rushed, under pressure.
"Aren't you going the wrong way?" Norman asked.
"Just checking the diesel backups."
Backups? Norman thought. Why check the backups now that they were leaving?
"She probably left something on that she shouldn't have," Ted said, shaking his head.
In the communications console, the mood was grim. Barnes was on the phone with the surface vessels. "Say that again," he said. "I want to hear who's authorized that." He was frowning, angry.
They looked at Tina. "How's the weather on the surface?"
"Deteriorating fast, apparently."
Barnes spun: "Will you idiots keep it down?"
Norman dropped his day bag on the floor. Beth was sitting near the portholes, tired, rubbing her eyes. Tina was turning off the monitors, one after another, when she suddenly stopped.
"Look."
On one monitor, they saw the polished sphere. Harry was standing next to it.
"What's he doing there?"
"Didn't he come back with us?"
"I thought he did."
"I didn't notice; I assumed he did."
"God damn it, I thought I told you people - " Barnes began, and then stopped. He stared at the monitor.
On the screen, Harry turned toward the video camera and made a short bow.
"Ladies and gentlemen, your attention, please. I think you will find this of interest."
Harry turned to face the sphere. He stood with his arms at his sides, relaxed. He did not move or speak. He closed his eyes. He took a deep breath.
The door to the sphere opened.
"Not bad, huh?" Harry said, with a sudden grin.
Then Harry stepped inside the sphere. The door closed behind him.
* * *
They all began talking at once. Barnes was shouting over everyone else, shouting for quiet, but no one paid any attention until the lights in the habitat went out. They were plunged into darkness.
Ted said, "What's happened?"
The only light came through the portholes, faintly, from the grid lights. A moment later, the grid went out, too.
