In this passage from In Cold Blood, Truman Capote seeks to describe Mr.Clutter as a lovely man through the way he interact with his wife Bonnie and daughter Nancy.
The ones close to Mrs.Clutter described her as having a “sheltering expression”; she suffered with her mental health and her husband stood by her side; even when there seemed to be no end to Bonnie’s dismay. Mr. and Mrs.Clutter can be compared to a “shadowed terrain sunlight”; she is filed with much despair that she cast a shadow upon her family’ while her husband is the sunlight that shines through her emotional termoral. Even when he disbelieved Bonnie when she tells him that the cause of her misery did not come from inside her mind; but is caused by a hurt “spine”; a “misplaced vertebrae”; he still wanted to hold onto some hope that she may return to her “old self”. This conveys he is a loving man. He wants to sit at Thanksgiving dinner with his family as it once was and give “unmarked gratitude” for not only his wife’s recovery but for her, who she is, and the "sheltering expression” that no longer is displayed.
Mr. Clutter is usually a stern man when it comes to his home and children, the “laws were laws”; but when it comes to his “real Southern belle”; Nancy, he becomes a gentle bull. Caring for his daughters every need and supporting all she does. He had even withdrew his own ”be home by ten” law just so Nancy could drive to Garden City to see “Spook Show” with her friends. This gentle bull was not all gentle when he sees red. Bobby Rupp was the epitome of this notion. Clutter had found him kissing his daughter and all he saw was red. Threatened by the possible corruption of his daughter; Clutter had suggested that Nancy “discontinue seeing so much” of the boy Bobby Rupp. He only wanted what was best for his daughter, and the boy was not. Throughout all this Mr. Clutter still keeps his loving status.
