I don’t know Steve, he had been planning this a long while, although Sheila’s illness helped him, I’m sure he would have found other ways and means of tarnishing his sister and his hatred for the family. He was so quick to offer all the dirt on his sister it’s as though it was rehearsed.
And naturally, what interests me most, is when that growing hatred first took hold. Might it be that, as a small boy, being groomed to take over the family business, admiring of his "father" though he may have been, he already knew that farming wasn't for him? Might it have been the moment he was told that the father he'd worshiped, and tried his best to emulate, was, in fact, not related to him at all? Might it have strengthened when, just a short time later, the, now, non father and non mother decided it would be best for him to be sent away to school? Might it have been when his non sister appeared to get her own way in everything? She didn't like one school so was allowed to go to another. She managed to escaped and PAID to do it! Hairdressing, secretarial work, modelling, generally living it up? All he had to look forward to was a life of drudgery. THEN, instead of coming back to some sort of secretarial position on the farm, where she may have been of use, she finds herself a hippy boyfriend, gets pregnant and married, in that order, and gets it all paid for. Might it have been, after her marriage failed, when she succumbed to mental fragility and chronic illness, that a deep rooted plan finally took hold? Might it have been then that he saw his life becoming the same old, going forward to middle age, to support her medical needs and fund her children? Might he have envisaged a very different life for himself, if only he could get his hands on his inheritance, whilst he was still young enough to enjoy it?
