Okay - I know there's another thread on this series generally - but I have a specific question that's bugging me that I don't think was addressed last night unless I missed it. Who was the 'postman' that Danny was arguing with? Remember the newsagent bloke who is dead, in his evidence he said he saw Danny arguing with a bloke in a high vis. vest on the road. ??? I can only assume it was Joe 
Apart from this niggle I really enjoyed every episode
