Interesting article Steve, can I ask you, what is your theory on what happened? X
I think Jeremy got disillusioned with farming and after the foreign trips finally realized that he was stuck in that employment until his parents passed away. He saw a way out when he overheard Sheila's comment that all people should be killed and it was in his mind some kind of practical joke(could we have the snippet of him pouting in the back of the Police van at this point) that would relieve him of his responsibilities, put Sheila, June and Nevill out of their misery and allow Colin to start again without having the burden as Jeremy saw it of two children hanging on like a millstone around his neck.
