I'm no one to question Agatha Christie but this book was totally ridiculous. It was supposed be to espionage but was reduced to an utter pile of fail. I really, really don't want to disrespect the Queen of Crime but Passenger to Frankfurt was boring, and along with being pointless it was also plotless.
It started off with a diplomat being asked to lend his identity to a woman on an airport or else she would have been killed and he agreed to it!
Now, why would someone agree to simply lend his passport and clothes to a strange woman on such short notice? This act of stupidity bothered me from the first chapter only.
Then comes the part where he tries to track down that woman - which was a little interesting but then the book took a major U-turn where it became all about creating another world with superhumans, swaying a crowd with words and all those Hitler concepts.
That's when I lost even the little interest I had in this book and started reading it just for the sake of finishing it. In the last couple of chapters a murderer/traitor is revealed - the topic which was completely sidelined in the middle and then comes a very unrelated epilogue and da-dum. Book is over.
What a complete waste of time. It takes me mere hours to finish Christie's books on an average but this time it took me 2 whole days! I think that says what a monotonous read this must be.
Not recommended to anyone. Not even hardcore Agatha Christie fans.
