You are getting very forgetful Adam you have been told several times in other posts that Bews and co could hear Crispy whining / barking as they approached.
He never mentioned Crispy in his massacre plans to Julie? strange I am sure he would have been concerned about the dogs. But everything in her WS could have been obtained elsewhere anyway.
Not at all. There was no mention of the hitman, nor a glove coming off in the fight with Nevill. There were no biographical details of their relationship, which gives the motive and the justification for the crimes.
