Anthony Horowitz has written a mystery novel within a mystery novel. It begins with a note from an editor, actually, a warning to the reader that “this book has changed her life” and that Magpie Murders is not the usual whodunit that one may be expecting to read. And indeed the reader will find that to be true about halfway into the novel. I found Magpie Murders to be one of the most clever mysteries that I have ever read, and I highly recommend it to fans of this genre. Horowitz has also written series for PBS television, including Foyle’s War and Midsomer Murders.
