The Girl in the Taxi is the English-language adaptation by Frederick Fenn and Arthur Wimperis of the operetta Die keusche Susanne, with music by Jean Gilbert. The German original had a libretto by Georg Okonkowski. The story begins with a man and a woman, both married, who flag the same taxi and then decide to share it, as they have the same restaurant destination. Various naughty supper rendezvous, and much hiding under tables or behind screens, ensue.

Arthur Harold Wimperis was an English playwright, lyricist and screenwriter, who contributed lyrics and libretti to popular Edwardian musical comedies written for the stage. But, with the advent of talking films, he switched to screenwriting, finding even greater success in this medium.
