An hour had passed since Annie had returned from her break. She sat at her desk, her blonded hair in a bun, and resumed work. As she was typing into her computer, the Doctor showed up with a metal dog in tow.
"Hello, Doctor, nice to see you again," she said slightly surprised, "What brings you here?"
"Hello, Annie, K-9 here has detected a strange signal coming from this building. I'm here to investigate. Oh, by the way, this is my dog, K-9," the Doctor said as he pointed towards the robot.
Annie leaned over her desk and looked at the dog as if she was a shy child meeting a new friend.
"The signal seems to be coming from the room straight ahead, Master," stated K-9.
"That's the Executive's office," she said taking her seat again, "What kind of signal is coming from there?"
"A signal that does not belong to Earth," the Doctor replied.
"You mean it's alien, as in extra-terrestrial?" said Annie
"You may put it that way if you like," the doctor answered, "Tell me, Annie, has your boss been acting strangely recently?"
"Yes," Annie stated, "He has been acting differently this afternoon. When I came back from my lunch break, he demanded to know why I was gone. It seemed like he forgot that I have a lunch break, but that's not the only thing. As he was yelling, I smelled this weird odor, which smelled like iron, but I…"
"That explains it!" the Doctor interrupted, "Annie, I have a feeling that whoever is in that office, is not your boss."
"What do you mean?" said Annie, "Do you mean that my boss is now an alien? You can't expect me to believe that."
"I mean that something is posing as your boss. Most likely that something did not come from Earth," said the Doctor.
"Extra-terrestrials?" stated a shocked Annie, "I find that hard to believe, but you do have a sonic screwdriver and a robotic dog. So why not."
"Well that's good. Anyway, I'm going to need to see the executive so I can figure out what's going on."
"Alright, I'll give him a buzz, see what he's doing," she then pushed a button on a speaker and proceeded to talk into it. "Mr. Anderson. There is a man out here who wishes to see you."
"Tell him I do not wish to be disturbed," said a voice from the speaker.
The Doctor got closer to the speaker and said, "It will only take a few minutes."
"No! I am very busy at the moment. Please come back at a different time. Good day," replied the voice.
"Good day," said the Doctor sounding defeated. "I need to get in that office. Something is definitely not right. Come along K9."
"I'm coming too," declared Annie.
"No, it could be dangerous," said the Doctor.
"So? You may need my help in there. After all I am his secretary."
"Fine, but don't say I didn't warn you."
The Doctor, Annie, and K-9 quietly headed towards the executive's office. The Doctor pulled out his sonic screwdriver, unlocked the door, and slowly opened it. The three of them entered the office and found the office empty.
"Where did he go?" said a perplexed Annie, "Mr. Anderson? How could he have left his office without us seeing him? There aren't any exits in this room."
"Perhaps he was teleported," stated K-9.
"Perhaps indeed," said the Doctor as he looked around the office. He then picked up a strange looking device. "K-9, is this the source of the signal?"
"Affirmative, Master.," said K-9.
"Can you tell me more about this device?" asked the Doctor
"Affirmative. Scan suggests device is used for communication. Device is known to be used by Zygons."
"Zygons, just as I thought. A Zygon must have taken my sonic screwdriver earlier and now one is posing as Mr. Anderson."
"Zygons? What are those?" Annie inquired.
"Zygons: a metamorphic species that can pose as any living being," K-9 defined.
"It would appear that a Zygon has taken your boss and has been impersonating him for at least a couple of hours," the Doctor added.
"Why would a Zygon want to do that and what does it have do with Mr. Anderson?" Annie questioned.
"I'm not quite sure. Perhaps they need his position for their plan, whatever it may be."
"Where would they have taken him?"
"They would have taken him to their ship I'd imagine."
"Is there a chance he may still be alive?"
"Oh, quite certainly. The Zygons need living specimens in order to take their form. The question is where is the ship that he is being held in? K-9, are you able to identify the receiving end of the signal?"
"Negative. The signal can only be traced if it is active."
"Alright then. K-9, I'm going to send a message through this device. I want you to find out where the signal goes," with that the Doctor started pushing buttons on the communication device. Then the device made a strange noise.
"The signal is being directed towards a ship located approximately 38.7852 kilometers to the west," K-9 responded
"That would put it near Lake Apopka," Annie stated.
"Not near in," the Doctor corrected
"What do you mean?"
"Well if you had a spaceship from another world, wouldn't you want to hide it?" he said as he began walking towards the door. When he was walking, a small cylindrical object bathed in an unnatural light appeared next to Annie. Within seconds the object rapidly released a whitish gas.
"Nerve gas!" he exclaimed, "Annie don't inhale it." but his words were of no effect as Annie was already coughing violently and on the verge of passing out.
Within moments Annie was out and the Doctor felt faint while trying to combat the fumes. Then two large beams of light appeared in the room. Out of those beams two Zygons materialized. They were tall, red, and covered with suckers. They had a strange, earthy smell to them. When they fully materialized, one of them closed the nerve gas canister while the other checked to make sure that they would not meet resistance. K-9 detected them and fired laser beams at the intruders to stun them; the Zygons had a type of shielding on them, so the beams were of no effect. They took no notice of K-9. Instead they made sure the room was clear, then took the Doctor.
