In The Essex Serpent, a widowed woman with a scientific mind becomes intrigued by a local legend and with her companion and odd young son in tow, she begins looking into things, much to the dismay of her London friends, some of whom are aware her rich, controlling husband was an abusive bastard and some who are not. (Cora has a scar on her neck in the exact shape of an ornate leaf decorating a candlestick that her husband once pressed into her flesh lhard enough to wound.)
The "mystery" of the serpent is eventually solved, but that particular plot thread is not the only one that holds our attention.
This is a character-driven book and the characters are fantastic. Cora is an extremely sympathetic character. For all her flaws (and her companion Martha freely points those out), she's also a generous woman with a prodigious intellect, a woman born a century too soon. (There are scenes where ehs has to endure "mansplaining" and has to bite her tongue and readers will bond with her over the experience.) But then there's Cora's complex relationship with her 11-year-old son Francis. She doesn't really like him and though she'd say she loves him, we sense it's only out of duty. He IS very odd, and nowadays would likely be diagnosed as being somewhere along the autism spectrum. But Francis is not just a gimmick of a character; he's fully realized and when he unexpectedly bonds with a sick woman, it is a touching and believable event.
Cora meets a kindred spirit in the most unlikely place--the local rectory. She's a Darwinist and an atheist and she's delighted that the local minister is open-minded and quick-witted, and more than happy to challenge her to debates on a subject both find fascinating. And meanwhile, there's mass hysteria at the village school, a missing girl, a Socialist who awakens the social conscience of a wealthy man, and more.
