A German language textbook giving twenty-five episodes of mystery and intrigue dealing with gangsters attempting to steal a secret formula for women's lipstick.
I bought this book for a dollar in the sidewalk bin at a used bookstore on Mission street in San Francisco. I was able to read it easily, so I guess my level of German proficiency is roughly what a U.S. high-schooler should have known in 1975. It was fun to read on the flight to Zurich.
