Magpie Murders by Anthony Horowitz, 477 pages
Editor Susan Ryeland has just been given the latest Atticus Pünd whodunnit by her cash-cow author Alan Conway, and immediately settles in to read the book. But just before the killer is revealed, the manuscript ends. When she tries to find the missing pages, she learns that Conway has died suddenly, thrusting her into a mystery of her own.
In Magpie Murders, Horowitz has created a book-within-a-book, a mystery-within-a-mystery, each as compelling as the other. I feel like I'd just read two books when I closed this one: the Agatha Christie-esque Atticus Pünd, and the more modern "real" mystery of Alan Conway's death and missing chapters. In doing so, Horowitz manages to both poke fun at and pay homage to whodunnits. I had a great time with both of these stories, and I highly recommend it to mystery readers.
