Identity Theft and Other Stories Book

This was a novella set on Mars. In the future, Mars is home to fossil hunters after ancient fossils were discovered there. I thought it was an interesting premise for an origin of a Mars colony. I loved the mystery story told from the perspective of a private investigator and Alex Lomax was a great character. I learned that this novella was expanded into a full novel called Red Planet Blues, I'd like to learn more of this universe, so that's definitely on my list.
