Ada Harris, a London charwoman in the 1950's, sees a Dior dress and decides that she's going to own one. First, she scrimps and saves her money, but when she has enough, and takes a trip to Paris, she learns that buying an original couture creation is a little harder than simply plunking down cash. Along the way to her goal, she manages to befriend a count, unite young lovers, and dodge customs.

In Tiger Bay, the docklands of Cardiff, rough-and-tumble street urchin Gillie witnesses the brutal killing of a young woman at the hands of visiting Polish sailor Korchinsky. Instead of reporting the crime to the authorities, Gillie merely pockets a prize for herself — Korchinsky's shiny black revolver — and flees the scene. When Detective Graham discovers that Gillie has the murder weapon, the fiery young girl weaves a web of lies to throw him off course.

When a nobleman is threatened by a family curse on his newly inherited estate, detective Sherlock Holmes is hired to investigate.

There had been some strange comings and goings the night the horse disappeared including a race tout trying to get inside information on the upcoming race.
