"So you saw the police box materialize out of thin air, and then three people walked out of it."
"Aye, Mr. Holmes."
John exchanged glances with Sherlock. "And when did this happen?"
"Just this morning." The heavyset man squirmed in the chair. "In Hyde Park. I've got a photo." He withdrew his cell phone from his jacket pocket and started looking at his pictures. Sherlock focused on him with cold, calculating eyes.
"Here," said the man, handing his phone over. John huddled over to view the small screen with Sherlock. A cobalt blue, old fashioned police box was situated between two trees. Neither Sherlock nor John had noticed a police box in the park before.
"Hhhhmm…" Sherlock thought as he twiddled his fingers. He then stood up from his seat. "This is a four. I don't leave the flat for anything less than a seven. John, do you think you could go have a look around?"
John Watson was accustomed to it, so he didn't even bother fussing. Both he and the man stood up, and John motioned for the door, "After you."
They reached the park in fifteen minutes. The man was chattering on about an array of small things; Which internet browser he prefered, how his nephews were doing, the color of his cat's sick, etc. "It was just here…"
The man scratched his head as he came up to the trees. There was no blue police box to be found. However, John's eyes noticed someone on the ground. Instincts took over and he lept over to the person, rolling them over to see their face. They were definitely dead.
The Time Lady danced around the laboratory, snatching up various tools, and returning to the large piece of machinery in the center of the lab. Moriarty was watching her very closely.
"So tell me, Master, that device, once finished, will draw the TARDIS from anywhere?"
"Please," she insisted, "Call me Missy."
"All right… Missy…" he corrected himself. He observed her pouring liquid in a tube. "So we'll plant a body everywhere that thing lands, leaving little clues for Sherlock to find how they are connected. Once he figures out the pattern, he'll know when and where the next victim will be killed, and he will be waiting."
"And we'll call the TARDIS, he'll go barricading in like a vigilante, and then POOF… send it off to another dimension," completed Missy, pulling a lever and looking into Moriarty's eyes.
"I love it… this is brilliant!" smiled Moriarty.
"Yes yes, it's quite devious. I can't wait to get them out of here and go back to where I came from," said Missy as she picked up a wrench.
Moriarty waited for her to turn around before he wiped his grin away and went back to analyzing what she was doing.
