A reread of a book bought back when £7.95 = R5.95, and when that was all a hardcover novel cost!
The film Gaslight came out in 1944. The term 'gaslighting' exploded into popular usage in 2016. Almost exactly half way between these two points of then-popular culture, came Sally Beattie's book ANNIE'S STORY (1983).
Annie Mainwaring's only friends are her dead uncle who speaks to her in aphorisims, platitudes and lyrics, and Horatio, the unfriendly cat.
After being undemined and overridden by her narcissistic mother, at age 50ish Annie becomes the target of 'Colonel' Carter, who has set his cap to finding a woman of independent means. After decades of being manipulated by her mother, her social isolation makes her a prime target for the colonel's avaricious intentions, and the gaslighting begins.
The previously mentioned grumpy cat did what grumpy cats do; the previously mentioned grubby colonel did what grubby men do; Annie did what downtrodden women seldom do, and claims her life for herself ... with no idea how to live it
