Who killed Wellington?

    I know Mr.Boone, Chris's father, killed Wellington because of a relationship he had with Mrs.Shears, it ended thus leading to the death. Mr.Boone is Mrs.Shears' neighbor and it was 2:00am so he must have been home. He used the pitchfork from Mrs.Shears garden and she didn't put it into her she

     I first thought he committed the crime because he's an alcoholic, tries to drink away his problems but that just leads to more problems and loss of memory."Father was sitting on the sofa watching snooker on the television and drinking scotch.There were tears coming out of his eyes"."And father was sitting down and she stood next to him and held his dad against her bosoms" which indicates that he was having a relationship with Mrs.Shears and it ended so Mr.Boone took his revenge.

     In this novel, I believe the red herring is when Mr.Boone says "Mr.Shears is evil" which to me indicates that he might have killed Wellington. Also I thought it was Mr.Shears because he might have wanted to get back at Mrs.Shears because of her relationship with Mr.Boone. But it doesn't make sense if you get back at them two years later.

     I know Mr.Boone killed Wellington because whenever Chris brought up the dog he would ignore it or say something like this:"It's a bloody dog,Christopher, a bloody dog", "leave it". Which makes me assume that he has something to do with it. Could mean that he has committed the crime and he's feeling guilty or having anxiety. When he says "Mrs.Shears is not a friend anymore.", that could mean his relationship is over with Mrs.Shears and he's sad about it because he can't "love".Meaning he has no partner and Chris doesn't like being touched or hugged, so everything he loves can't love him back. He killed the dog because of the way things ended with Mrs.Shears. Like I said before he loves to drink, so he probably committed the crime when he was drunk and late night because everyones sleeping.

With the evidence I have provided it is possible that Mr.Boone killed Wellington because of the way he responds to certain situations.This could've been prevented if both couples didn't go their "own ways" and then Wellington wouldn't have died.
