The Girl in the Taxi is the English-language adaptation by Frederick Fenn and Arthur Wimperis of the operetta Die keusche Susanne (1910 in Magdeburg), 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.
