Magpie Murders by Anthony Horowitz
I should have loved Magpie Murders. It's definitely a book for mystery readers. Not only does it have two well-plotted mysteries, it has some great quotes about the nature of mysteries and reading.
“You must know that feeling when it's raining outside and the heating's on and you lose yourself, utterly, in a book. You read and you read and you feel the pages slipping through your fingers until suddenly there are fewer in your right hand than there are in your left and you want to slow down but you still hurtle on towards a conclusion you can hardly bear to discover.”
“As far as I'm concerned, you can't beat a good whodunnit: the twists & turns, the clues and the red herrings and then, finally, the satisfaction of having everything explained to you in a way that makes you kick yourself because you hadn't seen it from the start.”
The set up is great, a novel within a novel, both murder...
