"Of what?" Fatboy asked.

"Of what the h.e.l.l do you think?" Tane answered a little testily, his head still throbbing.

Rebecca said, "Easy, Tane. Of the gamma-ray time-message-sender device, Fats. I have a feeling that we are going to need this, sooner than we thought."

"How soon?" Fatboy asked, but n.o.body answered.

Rebecca came back into the control room and, there being no spare seat, sat on Fatboy's knee. Tane stared out of the viewing window of the sub. He said, "I think I have a name for it."

Rebecca looked up. "Yes?"

"Well, it's like a telephone that sends text messages through time, right?"

"Well, sort of."

The name had floated into Tane's mind in between throbs of pain. Tele Tele was ancient Greek for "distance," and was ancient Greek for "distance," and phone phone was ancient Greek for "speech." So a "telephone" was a machine that let you speak across a distance. The ancient Greek word for "time" was was ancient Greek for "speech." So a "telephone" was a machine that let you speak across a distance. The ancient Greek word for "time" was chronos. chronos.

"It's a Chronophone."

Rebecca said, "I like it."

"Wouldn't it be a Chronograph?" Fatboy asked. "I mean, it's more like a telegraph, sending Morse code, than a telephone."

"Maybe, but a Chronograph is a kind of watch, so I think Chronophone is best," Tane insisted.

"Actually, Fatboy is right," Rebecca said.

"Okay, whatever." Tane shrugged and turned away.

There was an awkward pause. Fatboy coughed.

After a moment, Rebecca said brightly, "Chronophone will do fine. But what a paradox."

Tane groaned, "Oh, here we go. I suppose you want me to kill Grandad again."

"You killed Grandad?!" Fatboy asked.

"No, Fatboy, don't worry about it. What paradox?"

"Think about it." Rebecca's eyes were wide. "We're in the middle of sending ourselves plans for the Chrono...phone, right, from the future."

"This much we know already."

"But where did we get the plans from?"

"Which 'we' are you talking about?" Tane asked.

"Okay," Rebecca said. "Call the future Tane and Rebecca 'them.' Now, where did they get the plans from? From us, right?"

"From us?" Fatboy queried. "How did we send the plans to the future?"

Rebecca sighed with exasperation. "We didn't send them. We just hung on to them. Think about it. Tane and I are the future Tane and Rebecca, just not yet. So future Tane and Rebecca get the plans from us, but where did we get them from? From them! From them!"

"So who had the plans in the first place?" Fatboy asked.

"Exactly!" Rebecca thundered, leaving Fatboy no more the wiser.

"And this has something to do with Grandad?" Fatboy asked, and couldn't understand why Tane and Rebecca got the giggles.

"The plans must have come from somewhere," Fatboy insisted.

"Maybe this is one of those kinds of questions that our brains just can't comprehend," Rebecca said, wiping laughter tears from her eye. "Like the infinite size of s.p.a.ce. Or what existed before the universe."

"Or why in automatic cars you pull the gear lever backward to go forward, and forward to go backward," Tane contributed, and even Fatboy started laughing, in a confused kind of way.

Eventually Fatboy said, "Okay. So I don't really get all this paradox stuff, and I don't understand where the plans for the Chronophone came from, but did you guys ever think about what a weird coincidence this whole thing is?"

Rebecca, still sitting on his knee, twisted her head around to look at him. "Yeah, I know."

She idly lifted off his cowboy hat and put it on.

Tane asked, "What do you mean?

Fatboy hesitated. "Well..."

Rebecca said, "He means that us, well, you really, Tane, thinking up the idea of receiving messages from the future, just at the right time to stop Dr. Green and her Chimera Project, is a very unlikely coincidence. Right, Fats?"

Fatboy nodded. "Did anything else unusual happen, when you thought up the idea?"

Tane asked, "Like what?"

"Like, did you see anything, hear anything..."

Tane shut his eyes, remembering. "There was a shooting star."

Rebecca looked up sharply. "What?"

"The moment that I thought of the idea of messages from the future, I saw a shooting star. That's it. Nothing else."

Fatboy shook his head. "Maybe it wasn't an ordinary shooting star. Maybe the shooting star was actually a thought from the future hurtling through the atmosphere in some cosmic ray from the depths of the universe just before embedding itself in your brain."

Tane said, "That's nuts."

Rebecca was already adding it to the notebook where she kept the message dates and times. She spoke as she wrote. "Please remember to send a shooting star above West Auckland on the twenty-seventh of October at exactly nine-fifty-three p.m. That was the right time, wasn't it?"

"Close enough."

Fatboy grinned. "So maybe the whole thing wasn't Tane's idea at all."

"Bite me," Tane laughed. "I thought of it by myself."

Fatboy said, "Sure, with a little help from the future and their intergalactic brainwashing machine!"

He put his arms around Rebecca's waist and she leaned back into him.

Tane gritted his teeth. "I thought of the basic idea," he said.

His annoyance must have shown because Rebecca said, "He was only joking, Tane."

Tane snapped back, "Well, I'm sick of it."

He regretted saying it immediately. The confines of a submarine were no place for bickering and fighting, but the words were in the open now and there was nothing he could do about that.

"Easy, Tane," Fatboy said calmly.

Once started, it was difficult to stop, and his head was pounding.

"Easy! You blackmail us out of two million dollars, worm your way into our project, and start barking orders around like you're running the show. And you tell me to take it easy."

"Hey, Tane," Rebecca said gently.

"No, stuff it!" Tane shouted. "And stuff you! None of this, the submarine, the money, none of this would be here if not for me, and you just weasel your way into everything and take it all!" Even Tane knew that it wasn't the money that he was talking about.

"Chill out," Fatboy said, his jaw set.

"I'm sick of it," Tane cried, his voice suddenly hoa.r.s.e. "I'm sick of it and I'm sick of you."

"Enough!" Rebecca said suddenly and firmly. "That's enough, Tane." She stood and took Fatboy firmly by the hand and led him back into the sleeping cabin. She pulled the watertight door shut between the two compartments, pausing only to say, "We'll keep out of your way until you've calmed down."

The clang of the metal door and the whir of the wheel-lock turning were like a knife in Tane's chest. For some reason, he had thought she would agree with him. That she would tell Fatboy to back off and remember that he was just a one-third partner and there only by the grace of Tane and Rebecca. Friends since forever.

But it hadn't turned out like that at all.

"c.r.a.p!" he yelled suddenly at the top of his voice into the void of the water all around. "c.r.a.p!"

Then, after a quick consultation with the map, he changed course, just slightly.

It was a childish display of emotion. An ill-considered, impulsive thing to do.

And it probably saved their lives.

THE R RAINBOW W WARRIOR "Holy mother...," Fatboy said, his body still halfway through the doorway from the bunk compartment. "Where the heck are we?" his body still halfway through the doorway from the bunk compartment. "Where the heck are we?"

Tane stirred uncomfortably. He had slept in the driver's seat, and his back and neck now ached. He stretched, trying to work out the knots.

"Sorry about yesterday," he said.

"We all have days like that." Fatboy flashed a quick smile. "Don't worry about it."

Tane smiled. Fatboy picked his guitar out of a narrow locker, sat on one of the fold-down seats, and began to play. Music to soothe the savage beast, Music to soothe the savage beast, thought Tane. thought Tane.

Rebecca emerged silently from the compartment behind Fatboy and said nothing.

Fatboy asked, "Was it something to do with Rebecca? Do you not like that we-"

Tane interrupted, to avoid more pain, "I was just tired and grumpy, I'm okay now."

He avoided Rebecca's eyes.

"Where the heck are we?" she said at last, startling Fatboy, who dropped a chord but picked up the tune and continued.

Through the large twin gla.s.s domes of the Mobius, Mobius, the rusted bow of a ship reached plaintively out toward them. The water was clear and still, and the early light of the morning washed the bow in cobalt hues. The seabed around the ship merged with the blue of the sea behind, in a soft vignette. The railings of the bow were intact but encrusted with green and brown marine life. In death, the ship was the foundation of life. the rusted bow of a ship reached plaintively out toward them.

"The Rainbow Warrior, Rainbow Warrior," Tane said.

"Wow," Fatboy said, "it's amazing."

Beyond the p.r.o.ng of the bow, the rest of the ship lay on its side on the sandy bottom of the ocean, an artificial reef. The back of the ship was broken, and she lay twisted in her final resting place.

Tane wasn't quite sure why he'd diverted the sub. It just seemed like the right thing to do. For Rebecca.

"We are a long way off course," Rebecca said curtly.

"No," Tane said, "only a couple of hours. I...just...felt like a diversion."

"It'll cost us a day."

"But it's only a couple of hours out of our way," Tane protested.

"It means we won't make Motukiekie today. We'll have to stop over for an extra night, and do"-she hesitated-"the thing, tomorrow night instead. It's cost us a day."

"It's just one day," Tane mumbled. "I'm sorry."

"Tane, something bad is going to happen. We don't know what and we don't know when. One day extra might mean one day too late. We already talked about this."

c.r.a.p! Tane thought. Tane thought. c.r.a.p! c.r.a.p!

Rebecca's eyes were frosty, but she shut them for a while, and when they finally opened, they were clear.

"What a tragedy," she murmured, watching a school of colorful fish flit through the encrusted handrail on the point of the bow.
