Chapter 10
"Doctor!" Martha yelled. "It's getting closer!"
She looked down at the servant robot that was making its way up the tower, and sighed. The day had started so well...
They had decided to pay a visit to a 34th century human colony on Neptune. Unfortunately, one of the local servant robots had chosen that moment to go haywire, and was now chasing Martha and the Doctor to the top of the communications tower.
"Intruders detected," the robotic voice boomed. "Must be terminated!"
"Are you done yet?" Martha wailed.
"Almost!" the Doctor replied. "I just need to reverse the polarity of the signal coming from this antenna, and then override its positronic brain,-"
"Then do it!"
Martha took a few steps back as the robot made steady progress towards the top. They had less than a minute before it reached them.
"Must be terminated!"
It was now only a few steps away from them. Martha closed her eyes.
Suddenly, from a distance, she heard the sound of... something flying. When she opened her eyes, she could hardly believe them. It was a boomerang, flying towards them. Martha ducked as the boomerang passed by her and flew directly into the robot.
"Must be t-t-eermmm-in-..."
Martha turned to the robot. The boomerang was lodged in its head, and it was on the ground, completely motionless. She stood there for a moment, completely dumfounded by what had just happened. She then turned to face the Doctor, who was also looking at it, similarly surprised.
The Doctor picked up the boomerang. "Well, I have no idea that came from." He examined it closely. "It's just a normal boomerang. Huh." Aiming towards the sky, the Doctor threw the boomerang as hard as he could. It didn't come back, instead flying out into space.
"So, what was that?" asked Martha as they climbed down from the tower. "How did that boomerang come out of nowhere?"
"Probably some piece of debris drifting through the vortex." replied the Doctor. "Nothing too abnormal. But you know what's really wierd?"
"What?"
"It didn't come back!"
