Haven't seen the documentary yet but will do soon. Coming at this very late in the day and from a different angle, I know the Police looked at others with the same name as a possible mistaken identity murder but that is where I was drawn. It is a common name and the fact that the person at the door asked for Alistair Wilson, it sounded like he did not know that he lived there, or surely he would have just said "Is Alistair in?". Someone from the pub opposite would know exactly where he lived and what he looked like so to me it sounds like they did not know him. Even a hired professional killer would have known the correct person and location (opposite the Havelock Arms). So that brought me back to mistaken identity and no professional killer would use an Antique gun like that, too unreliable. So an amateur, getting the wrong person but what motive? The envelope with Paul on it was perhaps the best clue. My first thought was Paul the Apostle, a controversial figure in the development of Christianity, and known to engender strong feelings. Not 20miles away was the Highland Theological College and one of their Teachers went by the same name (not sure where he lived could be closer or further away). He published a Paper on Paul's letters to the Thessalonians in 2004 and has covered the subject in other papers subsequently. Is it possible that someone with extreme opposing views sought him out? Was this ever thought of as a possibility or am I clutching at straws, opinions welcomed. One final thought, I just don't buy the planning application theory, surely anyone annoyed with Alistair would have sent him a nasty letter, posted something disgusting through his letter box, shouted at him, beat him up, you get the gist, it makes no sense to kill him for that and as I have said, they would not ask for name confirmation as they knew him and the envelope makes no sense in this scenario. Just my thoughts, not sure if I am swimming against the tide here.
