This a revamped version of a story I started called "The Best Defense" as I began sketching the plot out a little more that title didn't seem to work so I renamed it something more appropriate. The previous version will be removed once this one has been posted.

The prologue below is essentially the same as before just expanded a little.

Enjoy.

PROLOGUE.

Southern England, near the Welsh border, five years ago.

The Corporal driving the land rover looked in his rearview mirror at his passengers. They were both women and he let his eyes linger on the younger of the two.

She was in her mid-thirties with clear blue eyes and curly auburn hair that was currently stuffed up under a black UNIT beret. Even without a hint of makeup and wearing a less than figure flattering UNIT uniform the driver could tell she was a very beautiful woman.

His eyes drifted to the other passenger. She was older maybe in her late forties or early fifties, but still very attractive. If the Corporal had known her when she arrived back in the 70s for her first tour of duty with UNIT he would agree that she'd barely changed at all. Her face had a few more lines and her honey-blond hair now had a few streaks of gray mixed in but she was still the same as she was all those years ago just a little older and certainly much wiser.

Sensing their driver was staring at them again the younger woman caught his eyes in the mirror and smiled at him. The Corporal blushed and quickly turned his attention back to the road.

Major Valentina Zebenlova looked back to the window at the world rushing by. The trip down from London had been long and uncomfortable and she was glad it was nearly over. Her fellow passenger had barely spoken a word since they left UNIT HQ two hours ago. Instead she'd spent almost the whole time staring at the photograph of the object they were coming to investigate.

The land rover suddenly stopped and Zebenlova noticed they had reached a checkpoint. An armed soldier approached the passenger side of the vehicle. She handed him her ID card and nudged her companion with her elbow.

"Hmm? Oh." She said absentmindedly as she reached in her coat pocket for hers.

The guard gave them a quick once over and returned them. He saluted the Major and waved the vehicle through.

Major Zebenlova noticed her friend watching the soldiers milling around the area. "We've had the area sealed off and a protective cordon set up." She said her voice still retaining that distinctive Russian accent even after spending nearly a decade in England.

"What cover story our we using?"

"An unexploded bomb left over from WWII. The demolition boys promise to have a nice explosion for us when we leave."

"What about the team working the dig sight?"

"They're currently under guard while Command decides what to tell the university about what they found. The Colonel seems to think that once they realize that signing the non-disclosure papers will allow them to return to working the dig once we've removed the artifact there shouldn't be any problem getting them to cooperate."

A few minutes later the land rover came to a stop again having reached their destination. The driver exited and quickly opened the door for the Major then ran round to the other side and did the same for the other woman.

"Major Zebenlova!"

Both women turned and saw a young leiutenant approaching them. He stopped in front of them and saluted.

"What's our status Lieutenant Reed?" The Major asked returning his salute.

"Secure ma'am. The bomb disposal unit arrived about thirty minutes ago and is making a good show of setting up. Once we give the word they can have a suitable explosive device ready for detonation within fifteen minutes and the ETA for the transport vehicle for the artifact is about twenty minutes."

"And the archeology students from the university?"

"Still under guard and not too happy about it either."

"Breaks my heart." Zebenlova muttered.

"Where's Nathan?" The other woman asked.

"He's waiting at the barrow." The Lieutenant answered. He turned his attention back to the Major. "Ma'am I've been ordered by Colonel Kaine to escort you and Doctor Grant to him as soon as you've arrived."

"Lead on Lieutenant Reed." Doctor Grant told him.

They followed the Lieutenant through the ruins of an fifteenth century church to an area just behind the ancient church. There was a large excavated area nearly thirty feet square with a stone structure set in the middle of it. It was still partially buried but a stone staircase had been uncovered that led into what the archeologists thought might be a Druid tomb of some kind.

Doctor Grant paused at the archway of the entrance for a moment. There was some kind of writing carved into the stone that resembled ancient Egyptian hieroglyphics. But that's impossible what would Egyptian hieroglyphics be doing on a 1000 year old Druid tomb?

Further into the structure, in the central chamber there was bustle of activity as several soldiers were busying setting up light stands while Major Zebenlova was conversing with another officer.

When the final light stand came on the officer nodded to Major Zebenlova.

"Alright clear the room."

Once they had gone the only ones remaining were Doctor Grant, Major Zebenlova, Lieutenant Reed and Colonel Kaine.

Lieutenant Reed was holding a video camera and was currently getting footage of the symbols on the strange object.

Colonel Nathaniel Kaine, a tall handsome man in his late thirties moved next to Doctor Grant who had not taken her eyes off the object since the lights came on.

"What do you think?" He asked her. "Jo?"

"I'm sorry." Jo Grant hesitantly stepped up to get a closer look. "It appears to be a sarchopagus and these hieroglyphics are certainly Egyptian, but these…" She pointed to the symbols next to them.

"Ring any bells?" Colonel Kaine asked.

She shook her head slightly. "Vaguely. I seem to remember something… but I…"

She reached out to touch the sun symbol and it moved. There was a loud hissing noise and suddenly the sarchopagus started opening. Major Zebenlova and Lieutenant Reed quickly drew their side arms and waited for their commanding officer to give the word.

Kaine and Jo saw a hand appear. Reed and the Major tensed up but Kaine waved at them to hold off. Slowly the figure of a woman rose up.

She gasped and took several deep breaths as she looked around. From the look on her face both Kaine and Jo could see she was very frightened. Jo starting moving toward the woman before Kaine could stop her.

She held her hand out to the woman. "Don't be afraid." Jo said softly. "We're not going to hurt you."

"…please… we need…" She whispered. Suddenly the woman tensed up and her voice changed. "Please…" They were amazed to see her eyes start to glow. "…you must help us…"

more to come…
