Dave, again I have to say I see no reason to disbelieve Alison. I know absolutely nothing about her except that she is probably female. If she had concocted this story for whatever reason I reckon she would have made sure the details were watertight: the apparent vagueness and/or inconsistency is just what I would expect of a story from my own first-hand experience of events ten years ago. I believe things happened pretty much as Alison relates until someone offers evidence to the contrary. If you choose not to believe her, fine.
