Magpie Murders by Anthony Horowitz

I picked this up because the author also writes the British TV series Midsomer Murders and the twists and turns in this book are just like the series with possibly less blood.  When mystery author Alan Conway sends the proof of his latest book, Magpie Murders, to his editor Susan Ryeland, the last chapter is missing - and Alan is dead - an apparent suicide.  But the character in the novel and the real life Alan share many similarities. Ryeland suspects that there are clues to be followed in this final book that will not only allow her to finish the mystery but also satisfy her growing belief that it wasn't suicide at all.  Serious mystery readers will probably recognize many Agatha Christie like characteristics. It made a great airplane read!
