It's 1924 and war widow fashionista Ginger Gold's new Regent Street dress shop, Feathers & Flair, is the talk of the London fashion district attracting aristocrats from Paris to Berlin to Moscow.

Ginger is offered her first job as a private detective when her sister-in-law's stage actor friend goes missing, and though the dress shop takes most of her time, Ginger takes the case.

But when a Russian grand duchess dies at the shop's official grand opening event, Ginger ignores the missing person to chase a killer. It's a decision she will live to regret.
