Their Frozen Graves by Ruhi Chowdhury

Two women found by a lake and they are strikingly similar. They are also very similar to a social activist Katy who lives nearby. When the detectives go to meet the family, they are taken aback because Katy is very much alive. This is where the actual mystery starts. On top of it all, Detective Mack is facing her own personal demons. Just separated from her husband, she is completely shocked by the re-appearance of her father who was supposed to have died twenty years ago, and whose corpse she and her mother secretly buried. Mack knows she has to be personal problems aside and deal with the investigation before her because there seems to be so much history behind the two mystery women who were murdered. There are plenty of secrets that have to be uncovered both in the two murders and in Mack's personal life and these are not going to be easy to face. Told only from Detective Mackenzie's perspective, the other detectives are just on the fringe the story is puzzling, and full of suspense till it all gets sorted out.
