I am currently reading Murder at Archly Manor by Sara Rosett. This book is the first in the High Society Lady Detective series and will be released October 15.
Unable to live with her domineering step-mother, Olive Belgrave moves to London, assured she can easily find a job and support herself. Unfortunately, Olive soon learns that jobs are much harder to find, even for an educated young lady in 1923. A call for assistance from a wealthy cousin turns into a job. After all, why pay a detective to ferret out information on a shady looking suitor, when the money can be kept in the family. Soon Olive is crashing a house party to glean information on the wily fiance. Circumstances change however when Olive sees a blonde woman shove him over a balcony to his death. Now instead of looking into his life, she's investigating his death and trying to prove her cousin innocent of his murder.
