"Look, I don't mean to be rude, but who the hell are you?" DI Greg Lestrade asked the tall, red-haired woman pointing around a strange metal torch that emitted a buzzing sound and had a green light faintly illuminating the areas she pointed it at.
"Hmm?' she replied, frowning as she turned it off and stared hard at it, her lips pressed into a thin line.
"Who are you?" Lestrade repeated himself. Sally Donovan snickered at her boss's predicament, knowing that any second the woman he was trying to interrogate was going to start talking and won't stop.
"Oh, sorry. Were you talking to me?" the woman finally looked at Lestrade, her sapphire blue eyes wide and innocent.
"Who are you and what are you doing at this crime scene?" Lestrade repeated crossly.
"Oh! Introductions!" She rubbed her hands together before offering her hand to Lestrade to shake "My name is Grace Yvonne Quae. I was examining the evidence." She crossed her arms and tipped her head to one side "And who are you?"
"Detective Inspector Greg Lestrade."
"Pleasure. Now, if you will excuse me, I must get back to my lab."
"Excuse me, sir. May I go outside for a bit?" asked Donovan of her boss.
"Yeah, sure." Lestrade was busy looking at the corpse. The man had been stabbed in the heart by a dagger that still resided there. He wore the clothes of a classic Highlander of Scotland. Based on what little he remembered of history from his school days, he seemed to be an early one. But that was impossible. How could a Highlander from 900 A.D. end up in modern day London?
Outside, Sally followed Grace to her 'lab'. Before she could enter, Sally called out "So this is the greeting I get for saving your life? Ungrateful Alien prick!"
Grace turned around, her eyes wide "Do I know you?"
"You should. I pulled your sorry ass out of a burning house in 1950 when you took me on a joy-ride in your brother's time-machine." Sally scowled at the female Time Lord.
"I haven't met you yet. Forgive me. I can't know anything about my personal future. What's your name?"
"Sally. Sally Donovan. You can find me at 223 Campham Road in Surrey in the year 1993 at about 3:00 in the afternoon. Remember to say that your name is Sister. It'll be funny because of what you wore that day. Say hi to the Doctor for me!" She ran back to the boss and the case. She smiled, thinking about how young the Doctor's kid-sister was.
