Upon Another Edge Broken

Murder has found its way to the colony of Edge.
Ash doesn't want anything to do with tracking down a killer. She doesn't want to delve into the anger and darkness that caused such a horrible event. It frightens her deep down into the core of her being.
But.
Well, it's just that she's curious. More so when she discovers the killer might not even be from Edge. Was this the murder of an innocent scientist, or an attack from a neighboring colony? Is this the culmination of a bitter personal dispute, or is this the start of a war?
To uncover the truth, Ash needs to become the greatest detective Edge has ever seen.
It's not like there's a lot of competition.
She can probably hit the top five, at least.
