Complex Regency mystery

Rosalind Thorne , daughter of Sir Reginald Thorne, (habitual drinker, gambler and forger), is supporting herself by offering her services to those wanting the know how around running the gauntlet of polite society. Years before, Rosalind’s father, heavily in debt, had fled to Paris taking her sister Charlotte, leaving behind Rosalind and her mother. Returning to England years later, Charlotte, now a highly sought after courtesan has relocated their alcoholic father to Bath in the care of minders. He escapes with the help of one Russell Fullerton, an opportunist not above blackmailing others. Indeed he’s well known for being a blackguard. Fullerton has plans to ruin Rosalind. When Sir Reginald is found dead, other factors come into play.
Currently Rosalind is helping a Mrs Walford throw a ball for charity. In reality she’s been hired to investigate a man the daughter of the house is being pursued by, a Mr. Horatio Salter.
Rosalind has become somewhat of a private problem solver for high ranking members of the ton. She has a close affinity with a Bow Street runner Adam Harkness. She is on speaking terms with Countess Lieven, a patroness of Almanack’s.
Indeed her forays into discreet inquires for others of high society has earned Rosalind more friends than she knows.
What she doesn’t anticipate is where her investigations for the Walford's might lead, including espionage and troubled rumours of Bonaparte supporters.
A well constructed, solid and enjoyable read overlaid with surprising revelations and a quiet romance in the wings.
