non-linear narration of a lifetime of investigations from the author

The author spent many years investigating, interviewing and trying to shed light on countless contradictions, lies and omissions on the process regarding Charles Mansons and the killings conducted by the family. The was a passionate, dangerous and frustrating work, many times obstructed by denials to obtain the information or even obstruct it. The author avoided building a linear narrative providing an alternate version of facts - that would make this a more easily digestible work but would simplify heavily on the findings, which most times were not irrefutable. He decided on presenting us with his journey. This makes it harder to grasp but allows us to learn many avenues he pursurd instead.
The historical facts and personalities involved and the account of this period of time are valuable. I wanted to learn about them and I did, even though carrying many of the author's doubts with me.
