My Grandmother was a huge fan of Agatha Christie, and read and re-read what she referred to as her “Aggies.” When I was about 12 or 13, and summer meant reading just for fun, I decided to find out what Gram found so appealing. I soon discovered why Christie is the world's best-selling mystery writer, with interesting characters, exotic (well, to me) locales and plot turns that kept me guessing to the end. Christie became my summer author of choice when I was a teen, and this summer, I am going to revisit her work. I’ll start with The Secret Adversary, and then move on to some Miss Marple. Gram would be pleased!
