I decided to write this in response to AryaUchiha1999 writing challenge. I do not own any Thunderbirds characters in this story.

Chapter 1

It was 5:45 am in the morning and the Tracys hated being woken up early. Especially after a big birthday celebration the night before. But the alarm had been sounded on the western perimeter of Tracy Island and Kayo Kyrano had decided to go check it out. She went alone, but had told everyone else to be ready in case she needed back up.

It was also a freezing morning as it was the middle of winter and even though Kayo was dressed for it, she still felt the cold bite of the wind as it blew around the island. She pulled her jacket closer to her and swept the beam from the light on her helmet around. The alarm had been triggered on the beach, so that's where she was headed.

"How's everything, Kayo?" John Tracy asked over the comms on Kayo's suit. John was the space monitor up in Thunderbird 5.

"Everything seems okay, John. I haven't arrived at the Western Perimeter yet," Kayo replied. She had a secret crush on the space man. But, something had set off the alarm. And whenever something set off the alarm on Tracy Island, it was always something bad. It can't be the Hood. Or the Mechanic, Kayo thought. They've both been arrested. She had bought her gun along just in case and pulled it out now as she neared the area. Kayo turned off the safety catch just in case.

Arriving at the western part of the beach, the African nineteen-year-old swept the area with the life scanner. It showed two persons lying on the sand half a mile ahead. She shone the light around the beach. Did not see anything.

She walked on cautiously. Why were the two people lying down? Were they injured? Dead? Dying? Kayo shone the head torch around the beach after she reached the spot. But she did not see anything. Where are they? She thought. Then, she turned towards the shore line and found them. Two people were half submerged in the water, lying in the sand. She turned her comms on again. "Scott?"

"Yes, Kayo?"

"I've found something. Two people lying half submerged in water," Kayo reported, her eyes on the two prone figures. I wonder how they got here? Kayo wondered.

"How do they look?" Jeff's calm voice came over the comms in her helmet. They had found him eight months ago and she was still becoming used to seeing him around the place. But it was good. She had her 'father' back.

Kayo replied that she was going in for a closer look. "Be careful, sis." This time it was Gordon, the squid, who spoke.

"Always," she assured them and proceeded forward. She knelt down beside the nearest person. The person was a female, looked about twelve or thirteen, had blonde hair that was soaking wet, and was dressed in a light blue, button-up top and khaki trousers. Kayo placed two of her fingers on the girl's neck. There was a pulse, but very faint. And in this cold, she was not going to survive much longer. The girl also had several scratch's and bruises on her face. Kayo pulled her out of the water and further up the beach until the female was under the canopy of one of the palm trees.

She went back to the other body. This one had short auburn hair and was lying on the person's stomach. Kayo flipped this body over with her boot. Also female, with a pilot's uniform on. Her face looked really blue. Kayo felt for a pulse. There was none. She pulled the body out of the water and searched for any sign of identification.

She found a wallet, pilot's licence and a USB device. Kayo called into Jeff and informed him of what she had discovered. She noted that near to where she found the two females, was a piece of wreckage from what she assumed was a plane crash. She then pocketed the wallet, licence and the USB, picked up the girl and headed back to the house.
