Cards on the Table (Hercule Poirot, #15) - Agatha Christie

"Copy! Copy indeed! People are so unintelligent. I could invent a better murder any day than anything real. I´m never at a loss for a plot. And the people who read my books like untraceable poisons!"

 

Poirot, Superintendent Battle, Colonel Race and Ariadne Oliver in one book. Brilliant!
