A railroad thriller/mystery! I enjoyed the story and the railroad stuff. I would read the next book in the series but unfortunately the author died. I'll have to keep a look out for her other books, though.

There was a light switch immediately to her left when she entered the back door, and then a second switch on the other side of the room at the door leading to the hall. She could handle one switch in the ON position when the lights were on, but when the lights were off, both switches had to be down or she didn't feel certain she could trust her eyes. -- page 125
