Passenger to Frankfurt

U S paperback cover by Tom Adams. This stunning cover again uses elements of the British cover. This is Christie's worst book and it would have been kinder of Collins if they had 'lost' the manuscript. The book starts in utter silliness - can anyone believe that a woman could get into the U K on a MAN'S passport? I have read this book a number of times and I still cannot fathom out the ending.
