Is Oscar Van Rhijn being scammed by Ms Beaton?

Is Oscar Van Rhijn being conned by Ms Beaton? Is Maud Beaton a scam artist! No one has met Ms Beaton before as she claims to have lived in France! No one had met her family! There is a rumour but no evidence that she is J Goulds illegitimate daughter! Where is her chaperone/companion/guardian that other wealthy young ladies have? Was the man in the office who Ms Beaton took Oscar to meet a 'Con Man', as shortly after we see him take a payment from Oscar! Why on earth would J Gould one of the most wealthy and influential billionaires of his day need his illegitimate daughter to secretly undertake important business on his behalf! Sadly, I think our lovable rouge Oscar is being hustled.
