I know some of you can't see this on the actual BBC website, but if you live in the UK you can find this story here: link
No. 1, Gallows Gate Road. Part One. Written by Rupert Laight. Illustrations by Brian Williamson.
The first thing the Doctor heard when he woke was the sound of something tapping at a window.
He sat up in bed, ran a hand through his tangled hair and stared around him. Where am I, he thought. This isn't the TARDIS. It's a bed. A very uncomfortable bed. What am I doing in bed? I haven't got time for bed. This is madness.
The Doctor tested his memory. The last thing he remembered...
Before you ask, yes, I already know who Missy is. This is just two theories I have that involve her.
Theory 1: Gus and the Orient Express
I strongly believe that Missy was behind Gus and the events of the entire episode, "Mummy on the Orient Express".
1. Gus was an AI, as was Seb, Missy's receptionist that she most likely created.
2. Gus wanted to study the Foretold and reverse engineer the technology keeping it "alive". And this technology could very well be similar to what Missy used on her Cybermen army made out of corpses, much like the Foretold!
Kerry Coldeen a welsh waitress has been abducted by aliens who want to dissect her to find out about the human race, can the Doctor save Kerry or will she become part of the Roswalions bloody experiment ?
