Hello everyone! I'm back and here is the sequel to Dangerous Secrets. This is a crossover between Thunderbirds Are Go! and The 39 Clues. Disclaimer: I do not own any of the Thunderbirds characters and equipment, nor do I own any of The 39 Clues characters. But I do own Rae and Adam. It is not absolutely necessary to read Dangerous Secrets first, but you can if you want to. Enjoy!

Two months and one week after Dangerous Secrets epilogue...

Scott Tracy relaxed on the beach in a deck chair. This was the life – sunny beaches, good meals (the restaurants in Perth, Western Australia served excellent food) and a week's holiday, free from his job in International Rescue. But, as much as he was enjoying himself, he still could not help calling into Tracy Island or Thunderbird 5 at least once a day to make sure everything was alright. He lazily watched as some seagulls landed on the sand near his deck chair and fixed him with their beady little eyes. Scott chuckled and threw them crumbs of some Turkish bread he had been snacking on.

As the seagulls gobbled it up, he realized that he had forgotten to call into International Rescue to make sure everything was running smoothly. He was still trying to get used to handing the reigns of IR to Jeff after holding them for years. He knew that they could all handle it, but the years of being leader and watching over his family caused him to daily check in.

He pulled out his phone to call his father and was about to dial the number when he happened to glance up at the sky and froze. His heart pumped faster as fear raced through him. Scott's training kicked in and he jumped off his chair. Other people had noticed the threat hurtling towards them and were screaming and running in all directions looking for shelter. Scott began directing people off the beach to a place he knew would protect them. "I'm part of International Rescue. Come on, follow me!" he yelled and turned and began running away from the beach, a flock of people following him.

But some people refused to listen to Scott and stood there on the beach and watched the deadly burning comet as it hurtled towards them.

TOKYO, JAPAN

Tanusha "Kayo" Kyrano stared out the window of the taxi as they travelled through Tokyo. She was dressed in a grey t-shirt and navy blue trousers. Rae sat in the seat next to her, wearing a blonde wig and blue eye contacts, and was wearing a black leather jacket and black trousers. Her mind went back to her very first memory.

#START OF MEMORY#

"Good night, Tanusha."

Tanusha smiled as her mother tucked her in bed. She was about two years old. " 'Night, Mummy," she whispered as her mother stroked her cheeks.

"Did you enjoy your birthday, baby?" her father asked as he suddenly appeared, leaning over her mother's shoulder.

"Yes, Daddy. I wish we could've gone fishing today, though," Tanusha sighed. Her father leaned down and kissed her on the forehead.

"We can do it tomorrow. A late birthday present," he suggested. Tanusha nodded. "Just sweet talk your mother into baking a chocolate cake," he winked.

There was a loud crash. Her father went to check on it. He got to the bedroom door, then it burst open and four people dressed in black, their faces covered, came in. One of them hit her father over the head and dragged him out. Two others grabbed her mother, who was screaming and crying. They dragged her out. "You should never have done it," one of them growled at her mother. The fourth came and picked her up and carried her through the house. Out the front, the person put her down on the grass and bent down to tie a loose shoe lace. Tanusha ran out through the front gate and down the street. Gunshots ran out and she heard them running after her.

#END OF MEMORY#

The next thing she remembered was Grandma Tracy feeding her while she sat in a high chair. Jeff had told her how he had found her hiding in an alleyway and took her in, taking care of her. She had remembered her parents names when she was eight, but they were not able to find them. Then about six weeks ago, Tanusha had received an anonymous e-mail. The sender's name was Ebenezer William Kyrano, her father's name. The e-mail had simply read S.O.S. They were not able to trace the source, so Kayo, with Parker's help, had begun investigating, sniffing around. They had finally found a person who claimed to know what had happened to her parents and where they were. She had agreed to meet at Daiichi Sankyo Building in Tokyo. She decided to bring Rae with her, with Penelope and Parker following along (they and the car were disguised) to protect them.

Kayo felt tears fill her eyes and quickly blinked so she would not cry. She prayed she would find her parents. Rae placed a hand on her shoulder. "It'll be fine," she said quietly. Kayo hoped so.

PERTH, WESTERN AUSTRALIA

"Scott? Scott, are you there?"

Scott turned on his com watch as he ran. "John, what is it?"

"I know you've probably noticed, but there appears to be a big comet heading your way. With several smaller ones going to hit after it," John informed him. "You need to get to that Research building. It's cellar will protect you."

"That's where we're headed," Scott grunted. Him and the people following him were thrown to the ground as something hit the beach. Standing up, ears ringing, Scott looked back and saw a large, smoking crater in the sand, the dead bodies lying around it. He had tried to warn the people to come with him, but they would not. They wanted to stay. And now they are dead, Scott thought sadly, wishing he could have saved them. He looked up just as the smaller comets slammed into the road. Some hit buildings. Parts of buildings fell onto the street, crushing people. Scott and some others were flung backwards as one of the comets hit the road close to them.

Scott was in a daze. His hearing faded out. A man's face filled his vision, was shouting something, but Scott could not hear him. The man pointed frantically in the direction of the ocean. Then his hearing came back. "-the water's pulling out, mister!"

What?

Scott blearily sat up and looked out at sea. The water was being pulled out. But he was still dazed, and did not comprehend. He heard someone, sounded like his brother John, calling his name. He snapped awake and stood up. He cried out in pain and looked down at his left leg. There was a big gash, and blood was coming out. Scott had seen the comets up close and there was something strange about them. They looked like bolts of energy up close, not comets. "Scott? Bl**dy pick up, please!" John shouted over the com watch. The desperation and fear in his brother's voice made him forget about the comets.

"John I'm here," he grunted, trying to walk a little, but his injured leg made it impossible. He ended up leaning on the man who had been pointing out a sea.

"Oh, thank God," John breathed. "I've been trying to tell you. Two of the comets hit the ocean. The water's pulling out!" Then Scott realised. That's why the water was pulling out. His blood ran cold. He looked back out a sea. A big tsunami wave was heading straight for the city. "Get to the nearest highest grounds NOW!" John shouted.

The trouble was, Scott could not walk and some of the people had been injured. Scott then saw that they were standing next to a skyscraper. "Everybody who is not injured, take the wounded and get inside the skyscraper as high as you can go!" Scott ordered. But he knew not all of them would make it.

People carried the injured inside. There was an elevator, but they could not use it when there was a tsunami. They would have to take the stairs. "Up the stairs!" Scott directed. They got to the second floor.

Then the tsunami hit the building.
