If you had been following the case on YouTube, etc., there is not much new here. Basically the author took all info available out there and put it together into a book. I wish a narrator with American accent was used instead of British, as it seems a bit incongruent.
It sometimes felt repetitive and presented the victim as “controlling, attention-seeking, and crazy” while presenting the murderer as “hard-working, best husband and dad, and submissive”. Relied heavily on social media posts and text messages but I did appreciate the family interviews.
