Wilde, Darcie. Rosalind Thorne mystery.

"Inspired by the novels of Jane Austen, this new mystery series set in 19th-century London introduces the charming and resourceful Rosalind Thorne, a woman privy to the secrets of high society--including who among the ton is capable of murder... The daughter of a baronet and a minor heiress, Rosalind Thorne was nearly ruined after her father abandoned the family. To survive in the only world she knew, she began to manage the affairs of some of London society's most influential women, who have come to rely on her wit and discretion. So when aristocratic wastrel Jasper Aimesworth is found dead in Almack's, London's most exclusive ballroom, Rosalind must use her skills and connections to uncover the killer from a list of suspects that includes Almack's powerful patronesses--and her own former suitor Devon Winterbourne, now Lord Casselmaine. Torn between her old love and a growing attraction to a compelling Bow Street runner, Rosalind must not only unravel the mysteries surrounding Jasper's death, but the mysteries of her own heart as well.."--
