"The spirits are coming

"The spirits are coming!" Anne shrieked.

The Doctor spun around to face Donna. "Every alien has a weakness! Think Donna, think! What weakness could this one have?"

Donna pulled a face. "Umm, I dunno, they're weakness is their…..eternal beauty…no, that's just silly –"

The Doctor interrupted her immediately. "I like that eternal beauty idea! What sort of objects would they use to make themselves eternally beautiful?"

Anne lowered her finger towards the squirming King. Time was almost up.

"Diamond shoes, rings, earrings, crowns –"

"Go back to the crowns, yes. Anne Boleyn, the Queen of England, she'd most certainly have a crown. So I'm guessing that's where you've hidden your life support system?" The Doctor yelled triumphantly, spinning round to face her.

Anne resisted the flames that were licking at her fingertips and smiled broadly. "You are quite the detective…"

Donna looked at the Doctor with a puzzled expression on her face. "How do you come up with this stuff?" she asked.

"Well, you know, the clues are right there in front of you, you just have to follow them…" the Doctor said simply.

"But you have lost, Doctor. The spirits from the half-world are here to destroy this world, and they shall crown me on the field of the dead. I have hidden the crown deep inside a forest, where nobody will ever find it!"

Donna held up her hand. "Hold it! Can somebody explain to me what this crown-life support thing is all about?"

The Doctor waved his hand in the air. "Yes, I can do that. You see this alien creature living inside Anne Boleyn is still technically just a dead person in a live person's body. It needs that extra energy to keep it alive. I'm guessing you stored the energy you received from the time barrier into this crown, and are some how feeding it into your system."
Anne clapped coldly and smirked. "Bravo, Doctor. Yes, an energy that keeps me from crossing over is stored in the tiara. As long as the tiara exists, so do I."

Donna stepped forwards suddenly. "Well that's a shame isn't it? Because while I was poking around trying to find you people, I found this in a wardrobe."

And she held up the tiara. "No forest after all, eh?"

"NO!" Anne screamed, and ignoring the cowering King she sprinted forwards. Unfortunately, Donna was far too quick for the helpless Queen. The tiara was in pieces on the floor long before Anne arrived.

The alien intruder suddenly stopped, looking dazed and confused, and swaying violently on the spot, the body of Anne Boleyn fell to the floor.

A silvery-blue shape twisted out of the Queen's mouth and burst into the air like a cork from a wine bottle. It flew around the hall, screaming and writhing, before descending upon the Doctor like a hungry hawk.

The Doctor didn't have enough time to react, and the blue mass of dead alien wedged itself between his pursed lips.

Donna jumped over the lifeless corpse that was sprawled on the floor and cried out in anger. "You can't have the Doctor! YOU CAN'T HAVE THE DOCTOR!"

The alien spirit dug itself deeper into the Doctor's mouth. The Doctor looked oddly serene, as if he did not know what was happening. His eyes were blank and his senses seemed to be slack.

Donna tottered forwards, hair swinging behind her, and gazed around desperately for something to attack the creature. And then it came to her. It was the only thing she could think of, but she was sure it would work.

Bending down, she grabbed the screwdriver from the Doctor's open hand and pointed it upwards, as the last few cells of the blue creature disappeared into the Time Lord's mouth.

"How do I turn it on?" Donna said loudly, and she suddenly felt a warmth travel up her arms. Looking down, she saw the screwdriver flicker into life.

"Right then, Mr. Alien, it's time to call it a night!" Donna said spectacularly, and she aimed the blue light from the screwdriver onto the last atom of alien mass as it slid through the Doctor's lips.
