Signal Failure by David Wailing

Emily is heading home on the tube.  It's well past midnight and the train is fairly quiet.  Then it stops and all the lights go out.

This is a short(ish) story that's setting up for a bigger story.  It's quite insular and creepy.  The descriptions of the disused tunnels and rooms are very atmospheric and I felt like I'd been there.

After reading this taster, I'm definitely looking forward to the main course.
