My problems with the POW theory are:
- the police attended the pub and interviewed the relief landlord the day after Suzy went missing and knew about his part in her story, i.e. he was known to them, the situation was known to them. He would have been considered. THey knew about the phone calls between him / his wife / Suzy / her bank, and they knew she had plans to go there and collect her items. This scenario would have been considered.
- it requires either a complex conspiracy (the relief landlord is part of a group of people who conspired to abduct Suzy through a complicated plot involving stealing a postcard, a chequebook and a pocket diary and then having the relief landlord pretend to find these items, call her bank and arrange for her bank to get them to call his wife at the pub at a time when a stock take was going on and the regular landlord might still be around. Or at the very least a conspiracy silence between a group of people to cover up either a spur of the moment, brutal killing or an accident as the relief landlord was not alone at the pub, his wife and probably other staff must have been there.
-- A body lying in a cellar under some rubble where people do and could access for decades is not that plausible, and if the body was moved in the small window of time that would have been available it would have been done with the knowledge of others, who amazingly kept silent about this horrific event for decades, every day being terrified that someone woudl find the body.
-- we are not privy to most of the evidence and intel that the detectives working on the case are
I don't know, when you break it down, it doesn't seem that convincing any more.
