Yes he said that.
Ive revisited ep 1-4. Things I noticed:
Clearly Elmer Weysmith is based on Jonathan, guardian of the estate, his Roland-alike son scampering around at his command. It wasn’t him.
Jonathon’s brother / BIL, Eliot’s father, is very shifty and in need of money in Corfu (where Jonathon also appears as himself, the elder son). He looks horrified when it’s pointed out the penalty for murder would be death by firing squad. We know very little about E’s real-life father, except that he and wife moved to America and he’s returned not very rich.
The Doctor was one of Miriam’s lovers. She gave him his cars / money for them.
The doctor covered up Miriam’s murder because, why? Life insurance or, more likely, other things would come out. There’s something significant about the taxidermy; the chemicals used, the doctor’s treatment of Miriam’s husband. The doctor and his wife detest child-Eliot because he was ‘sneaky’. He must have know something about the doctor, what, bumping off the husband?
I’ve been trying to work out who Sophie is in the present day. Is she the tour-guide, partner of adopted-bother Fred? Could she be the doctor’s daughter? She knows way too much. Sophie at the will-reading looked horrified and said ‘she can’t have been (poisoned)’, in a way that suggested she knew something else.
Gillian was my other thought but that doesn’t seem right. She acts almost like a nurse appointed to look after Eliot, rather than his wife.
Luan (sp?) the driver / gardener is important.
