How to Catch a Moving Train

I'm not good at descriptions, so here's the prologue:
I deserve a donut. I really do.

Here I am, quite selflessly, if may add, sitting in a jail cell after doing NOTHING wrong. Sure, harboring a fugitive, resisting arrest, tampering with a crime scene- those could be looked upon as arrest-worthy offenses, but...

I had a really good reason.

And I was about to have PROOF regarding the validity of that reason when, well, I'll get to that.

But for the moment I was here, in this thick-aired British jail, very deserving of a donut.

I heard a thick cough closeby and covered my face with my sleeve. Ugh, just think of all the diseases floating around here.

Oh, please God, don't let that random cougher have Tuberculosis.

Well, I guess it's about that time I tell you how a bright, thoughtful med student from the states like me got herself in this mess of a conspiracy filled with bombs, double agents, twins, and some accents that may or may not have clouded my judgement.
