A Twist in Time by Julie McElwain

This is such a fun series because the main character takes everything in stride refusing to act the part of a lady and instead doing the unthinkable - using her brain to solve a murder! Kendra is once again using her FBI skills to help get her boyfriend Alec off for the nasty murder of his ex-mistress who happened to be with child - aghast! Using all of the Duke's connections and help from her female friends in the Ton she will place herself in great danger and have to fight crime wearing uncomfortable shoes and too many petticoats. My only thought was in wondering how long it will be before Kendra finally bends to society's rules and marries Alec. For those who did not read the first book, there are enough hints for the reader to figure out that Kendra was a former FBI agent who traveled back to Regency England and for reasons unknown, can't return to the present.
