Elephants Can Remember

Elephants Can Remember - Agatha Christie I should probably be happy now,but I am not,I am so sad,why?? Because,I was ready to be wowed.But this book failed to do that! Never have I read a Poirot mystery,which I could see what had happened how and why sooner than Poirot! It was my wish to be able to outsmart him,but I was wrong.I want him to be one step ahead of me,not me ahead of him! That's so sad!!
I should have read a better known novel by Agatha Christie,not this one! But I don't give up on her!
