This isn't a murder mystery or thriller. Nor is this a horror story about shamanism. All those are cover for a study on basic human emotions. With a few murders to fill in the blanks.
People are selfish, people can be greedy, people can hold a grudge and shape a lifetime of experience and impression. The harder question is why can't people change ? Is personality hard wired or is it how one's mind fixated/dwell to much on the past that we can't get out of its trap? Nature AND nuture.
There are two stories to show all this. First the burial ground inheritance between two siblings. Which is also interwoven with land dealings. Second is the history of two detectives.
In both cases, emotions clouds judgement, which limits or hinders communication, and builds walls.
You really must have patience on this one. It has not the usual comedic relief but tension, albeit a slow burning one.
