Agatha Christie publishes Passenger to Frankfurt

When a bored diplomat is approached in a bleak airport by a woman whose life is in danger, he agrees in a moment of weakness to lend her his passport and boarding ticket.

Suddenly, Stafford Nye's own life is on the line, for he has unwittingly entered a web of international intrigue, from which the only escape is to outwit the power-crazed Countess von Waldsausen who is hell-bent on world domination through the manipulation and arming of the planet's youth, which brings with it what promises to be a resurgence of Nazi domination.

The book is noted for its ambiguous ending, unusual for Agatha Christie.
