A dying wish. A secret world.

Can this grieving investigator stay on the right track?

PI Kelly Pruett is determined to make it on her own. And juggling clients at her late father's detective agency, a controlling ex, and caring for a deaf daughter was never going to be easy. So she takes it as a good sign when a letter left by her dad ties into an unsolved case of a young woman struck by a train.

Hunting down the one person who can prove the mysterious death was not just a drunken accident, Kelly discovers this witness is in no condition to talk. And the closer she gets to the truth the longer her list of sleazy suspects with murderous motives grows.

On a crash course with a killer, she must piece together the puzzle of what really happened to the victim that rainy night, before her own fate is sealed and she loses everything near and dear, including her life.
