unfortunately the impossible is true
Doctor,
Am writing this from prison cell in Pentonville due to inability of Sherlock Holmes to grasp that mysterious tracks in corridor due to Dalek treads, that our disappearance and reappearance in the locked room was assisted by Tardis, and that you are in a weird Time Lord coma and not actually dead. He keeps on talking about logic and when eliminated impossible, etc.
I figure that if I write this now, you'll read it in the future and then come back and sort things out. Right?
Am in fifth cell on left.
Please don't take too long about it.
