THE BENEVOLENT SOCIETY OF ILL-MANNERED LADIES

Three interlinked stories that give their twin heroines a chance to shine in much more physically active roles than early-19th-century England would ever have allowed.

It seems the fate of 42-year-old spinster Lady Augusta Colebrook to be constantly called on to rescue other women from the clutches of evil men and male-dominated institutions, and the fate of her widowed twin sister, Lady Julia, to be swept along as her accomplice while they keep their snooty and entitled brother, the Earl of Duffield, ever in the dark. After a spirited prologue suggesting a lower-tech James Bond pre-credit sequence, “Till Death Do Us Part” is kicked off by a report from Georgina Randall, an old friend of the twins’ late mother, that Millicent Defray, one of her daughters, suspects Sir Reginald Thorne of having imprisoned his wife, Caroline, Millicent’s sister. Gussie’s plan to find and free Caroline brings her into close contact with Lord Evan Belford, back in England after having been transported to Australia for a fatal duel he fought 20 years ago. The sparks between the two are so quick and hot that it’s no surprise to see Lord Evan, aka Jonathan Hargate, return in “An Unseemly Cure” to help Gussie rescue Marie-Jean, a 12-year-old who’s been kidnapped, kept in a brothel, and offered as a Virgin Cure for the pox, or in “The Madness of Women,” in which Gussie eagerly responds to Lord Evan’s plea to help him spring his sister, Lady Hester Belford, from Bothwell House asylum. All three adventures are marked by successively mounting complications that fans of either the Regency period or take-no-prisoners feminism will cheer.

Think of the Bridgerton novels with the steamy sex replaced by female-forward action sequences.
