Clues from author's intent

Every murder has its motives. Assumed motives only can be proved by adequated evidences. Trifle the murder story although gives assumed motives but no assured evidences. This story satirizes Men's carelessness and self-righteous reasoning that blinds their eyes and minds. On the contrary, women's opposite provides more and more clues and reasonable evidences. However, they seem assume John's wife strangled her husband because to revenge her husband wrung her canary's neck, there's no evidence to prove John killed the bird for what motives. Story itself although provided some details about John and her wife's conducts, relationship, and ect., they are all weak to suggest the murder motives. Therefore, i rely on author's intent as her purpose on this story to find its real clues. Clearly, the investigators don't help but instead sneer the women's careful seeking for evidence. Thus, i depend on the women's assumptions also it's author wanted us to depend on.
