The Mysterious Affair at Styles by Agatha Christie
I'm not sure how I have never read a Hercule Poirot mystery until now. (I have read Giant's Bread written under Agatha Christie's Mary Westmacott pen-name.) After watching the 2017 version of Murder on the Orient Express, I decided I was missing out. I was right. Agatha Christie weaves a well-written story of intrigue with nearly every character as a possible suspect. Even with all the clues on the page, Poirot doesn't "play his hand" until the end when the solution to the crime is revealed. I am excited to read another...and another.
