For the twenty-fifth book in the challenge, I read <a href=”http://www.goodreads.com/book/show/16352.Black_Coffee” target=”new”>Black Coffee</a> by Agatha Christie.
This is one of her Hercule Poirot books, and it actually started as a play. You can tell by the little things, when two characters ask a whole roomful of people to leave the room so they can have privacy, rather than move into the next room themselves. It was adapted into novel form by Charles Osborne.
In this book, a famous scientist contacts Poirot, fearing that his work as a physicist for the government has made him a target. Unfortunately, Poirot arrives too late to save the man, and must settle for catching his killer. I gave it four out of five stars.
