The Tuesday Club Murders by Agatha Christie

Although this book is presented in chapters, like a novel, it really contains thirteen short murder mysteries: two sets of six told over dinners, and one which Miss Marple prompts Sir Henry to solve. I particularly liked Miss Helier's story; it had a really unique twist. There's not a lot of action as almost all the stories are retold, but it's very enjoyable, and would be good to read over a period of time as you wouldn't have to remember much from sitting to sitting.
