Passenger to Frankfurt - Agatha Christie

I have about 35 pages left of this book, but I´m afraid I´m quite drunk at this point. Well, let´s say tipsy, it doesn´t sound quite so bad. 

 

I have to admit, it´s the proper state to plough through this book, because

 

a pacifying drug has been mentioned, which probably will cure all the young, Arian, misleaded students of their sickness, delusion, whatever ... at least I think so. I´m sorry, but I am drunk. And I´m dreading the end. What can possibly happen? Based on the rest of the book, it can´t be anything good.
