In one of those circular associations, that have occurred to me so many times that I am no longer surprised when they happen, I recorded the name of the estate as being Aswarby Hall. And when I researched M J James later I read that Aswarby Hall is the name of the house in the M R James story Lost Hearts (with the infamous hurdy-gurdy music in the BBC adaption). A lot more time needs to be spent going into all this.
