Tom admitted that JANIG didn't know much. After all, he pointed out, it was impossible to check everyone in an office building of that size, or at least impractical. Furthermore, it was a cover operation, and any kind of a careful check on people in the building would warn them that something was going on. Tom agreed, however, that it was better to be safe than sorry. JANIG would run a check on the barber, even though Rick's evidence was no evidence at all.

Rick wasn't satisfied. He felt he had to talk it over with Steve Ames, and called the agent, who was in JANIG's New York office, as soon as he got home.

There was a small switch box next to the telephone in the library. It had only two positions, one marked "normal" and the other not marked at all.

Steve asked, "Who is it?"

"Rick."

"Throw your switch."

Rick did so, with no apparent results. "Nothing happened," he said.

"Nothing audible," Steve corrected. "I threw mine at the same time.

We're scrambled. Go ahead, Rick, what is it?"

Rick told him the story. Steve didn't laugh. He had had experience with Rick's hunches before. "All right. I've already talked with Tom Dodd. He told me the story and I agreed we should run a check. He also reported that Weiss had persuaded Marks to come to Spindrift so the team could work together. I have Dodd planning how to get him out of Washington."

"Tom told me why no check had been run on the people in the building," Rick said hesitantly. "Honestly, Steve, I thought you always checked on everyone who might have a connection with a case."

"We do," Steve said flatly. "But we can't check on everyone in the city of Washington. Consider, Rick. There are several hundred people that work in the building and perhaps as many more who go there regularly for perfectly legitimate reasons. We couldn't run a deep check on all of them, and a superficial check wouldn't mean anything.

So we don't check. Instead, we make sure we know about the people the scientists see regularly, and we give physical protection not only to the scientists but to the floor they work on. We keep a careful check to be sure our phones aren't tapped, and there's a scrambler on each line. Of course the moment we get even a slight odor of fish, we run a check. That's why we're working on your barber right now. We're also checking the elevator operator."

"All right. I was off base, I guess."

"Not at all. I'd be disappointed if you didn't ask for explanations."

There was one other question in Rick's mind. "How do you know we weren't followed back to Spindrift?"

Steve chuckled. "You had two cars on your tail. They'd have picked up anyone who tried to follow Tom. What's more, our men at the airport identified every plane that took off from the vicinity of Washington for two hours after your departure."

Rick said sheepishly, "Sorry, Steve."

"Forget it. I'll be in touch with you, Rick."

Steve was right, of course. JANIG was on the job and would plug any loose holes. And once Marks arrived, Spindrift would be the only base the JANIG men had to cover. That would make it simpler. Rick decided he might as well put the matter out of his mind.

Barby, Jan, and Scotty were waiting for him on the front porch.

Scotty asked, "What gives?"

"Steve says to forget it."

Jan frowned, her pretty face worried. "Barby told me about these odd hunches you sometimes get. Aren't they ever wrong?"

Rick grinned. "I'll say they are. Don't worry, Jan. You're safe here."

Her dark eyes flashed at him. "I'm not worried about myself. I'm worried about my father."

Rick apologized. "I didn't mean that quite the way it sounded. But don't forget, Jan. Our father is in this, too. So we'll worry with you--if there's any worrying to be done."

Barby changed the subject. "It's still early. Why can't we give Jan another swimming lesson?"

They had started the day before teaching Jan how to use underwater breathing apparatus. She was an excellent swimmer, almost as good as Barby. But she had never had experience with mask, fins, and snorkel, so lessons in the use of those were required before she could graduate to the aqualungs.

"Let's go," Rick said.

In a short time the four had changed to swimming suits and were testing the water off Pirate's Beach. It was cold, but not unbearable.

Once they were accustomed to it, Rick picked up the instructions where he had left off the day before. Jan was using Barby's mask, snorkel, and fins. They would get her some of her own on the first trip to Whiteside.

Barby had borrowed her father's equipment. The mask wasn't a perfect fit, but she was experienced enough not to mind a little leakage. The snorkel was all right, since no fit was involved, but the fins were ludicrous on her small feet. She had stuffed cotton in the toes to make them tight enough to wear, but that made the fins hard to control.

"Follow the leader!" Rick called. "I'll lead, Jan next, Scotty next, and Barby bring up the rear."

That was so Scotty would be instantly aware of any trouble Jan got into. Barby could swim as well as either of the boys and needed no watching.

Rick started by going straight out, watching the bottom through his mask. When he got to about the fifteen-foot depth, he bent at the waist and threw his legs upward. He slid smoothly into the water, rolling on his back to watch Jan. She imitated his movements perfectly, and he turned back, satisfied. She was graceful as a seal in the water. It wouldn't take much to make a first-cla.s.s diver out of her.

Rick went to the bottom and moved along, doing underwater acrobatics and touching a rock here and there. Then he turned over on his back again and started upward, eyes on Jan. She followed. He led the way back to the beach.

As the group emerged from the water and lifted their masks, Rick looked at Scotty. His pal nodded. "She'll do. She followed you like a shadow."

"Good. All right, Jan. Next step is clearing your mask of water. The principle is easy. Just remember that gas is lighter than liquid. Your breath is lighter than the water. So you hold the top of your mask and blow it full of air, which forces the water out the bottom. Watch."

He demonstrated a few times, then Jan tried it. She caught on easily.

The instruction continued, until at the end of two hours, Rick took all of Jan's equipment and threw it into twelve feet of water. "Now,"

he said calmly, "go after it and put it on in the water. Clear your mask and snorkel, then come back to sh.o.r.e with full gear on and operating. No surfacing to take a breath. Use only the snorkel."

Jan looked into the water thoughtfully. The moments ticked by. Finally Rick asked, "What is it?"

The girl smiled. "I'm planning how I'll do it. If I don't plan in advance, it will be too late after I've started, and I intend to do it right the first time."

Rick, Barby, and Scotty exclaimed together, "Good girl!" They laughed, and Rick explained, "That's what makes a safe diver. Know what you're going to do before you have to do it."

Jan filled her lungs and dove. The three swam out over her and watched through their masks. She found the mask, and there was a bad moment when she got it on upside down, but she quickly reversed it, held it to her face, and blew it clear. Only then did she bother with the strap that held it.

Rick watched, pleased. He hadn't told her it wasn't necessary to attach the mask before clearing. She put the snorkel mouthpiece in place, but did not bother to attach the rubber strap to her head.

Then, working smoothly but without waste of time, she slipped on the fins and flashed to the surface. The snorkel emerged and she blew it clear, then swam to the beach.

"Perfect," Rick applauded.

"You're a natural," Scotty added.

Barby just beamed.

Jan was obviously pleased at their praise, but she was a little shy, too, so she contented herself with smiling her thanks.

"Aqualung instruction tomorrow morning," Rick said. "Come on. I've worked up an appet.i.te."
