Passenger to Frankfurt

Sir Stafford Nye's flight home from Malaya takes an unprecedented twist when a young woman confides in him that someone is trying to kill her. In a moment of weakness, he agrees to lend her his passport. Unwittingly, the diplomat has put his own life on the line. When he meets the mystery woman again, she is a different person, and he finds himself drawn into a battle against an invisible—and altogether more dangerous—enemy. . . .

Agatha Christie is the most widely published author of all time, outsold only by the Bible and Shakespeare. Her books have sold more than a billion copies in English and another billion in a hundred foreign languages. She died in 1976, after a prolific career spanning six decades.
