Alyce I am sure you wrote somewhere that you know this area of Cambs. or had driven past the Royston Home. I had a look at Ian's old home that he shared with Diane and I noticed that that was a converted barn. I couldn't find the age but I did idly wonder if that was not on mains sewage.

Ultimately it doesn't matter but it had never occurred to me as a place to hide a body and it's such an odd thing for the
old owner to say about H.Lodge IF it was likely to be ever drained. (Appreciate all systems are different and no idea how long it takes for an
inactive system to clear of crust. Could be decades.)
I'm only idly wondering as there was no hearing today so there's nothing new today.... so what might he be happy to leave the following occupants to deal with- whoever they may be - after he himself had died.
