The City of Masks — George Barr Mccutcheon

The city is New York and the masks are worn by titled foreigners whose fortunes have fallen so low that they have drifted into employments much below their station in life. Once a week the Princess who runs a pawnshop, the Lord who is a chauffeur, the titled English governess, and their friends gather at a salon held by the Marchioness who runs a fashionable dressmaking establishment. The governess is the real heroine of the story and her love affair ends happily after many exciting adventures.
