Rosalind Thorne makes her way in a male-dominated society by helping the ladies of London’s haut ton resolve all sorts of domestic dilemmas. Most recently, Marianna Levitton has sought Rosalind’s help finding her niece, Cate, who disappeared from her house in Bath after a sojourn there. Marianna doesn’t know that Cate’s been living upstairs at the house Rosalind shares with writer Alice Littlefield ever since her niece was brought there, obviously sick, by Amelia McGowan, their housemaid. The presence of Cate, Amelia’s onetime paramour, upsets the deepening relationship between Amelia and Alice and puts Rosalind in a precarious position with Marianna and Beatrice, Cate’s mother. While Rosalind tries to sort out the Levittons’ domestic affairs, Bow Street runner Adam Harkness hopes to make her an offer of marriage by earning the reward offered for the capture of the fugitive George Edwards, a key figure in the Cato Street uprising. In between the two quests stand Jack Beachamp and Francesca Finch, a pair of miscreants who see fit to meddle in both family conflicts and matters of national importance. Fitting together all the pieces holds the key not only to solving the intricate puzzle but to finding a path forward in Rosalind and Adam’s life together.
