In Cold Blood (outside reading book)

I have observed quite a lot about Capotes writing in, In Cold Blood thus far through the novel. Capote's writing is very distinctive in the way he uses description. Capote paints such a clear picture with not only the landscaping, but also the actions of people. He goes into such tiny details to how the eople thought, like hoe Mr. Cluter liked "apple eating weather" and how Mr. Clutter felt about Kansas being perfect if there hwas just an inch more of rain.
I do wonder how he managed to paint such detail of each family members final day(s), however, since they clearly cold not be interviewed. I think it is possible that he used some fiction , especially for Mrs. Clutter. She was so reclusive that it seems impossible to have reconstructed her last day factually.
THe book is well written with respect to detail if not just a bit over detailed in some spots. ther are times when the details become overwhelming and no longer do i have a clear picture in my head, but i am falling asleep. But, regardless of my opinion, i find the book fascinating to read thus far and will continue to!
