The Murder of Roger Ackroyd
"The Murder of Roger Ackroyd" is the supreme, the ultimate detective novel. It rests upon the most elegant of all twists, the narrator who is revealed to be the murderer. This twist is not merely a function of plot: it puts the whole concept of detective fiction on an armature and sculpts it into a dazzling new shape. It was not an entirely new idea ... nor was it entirely her own idea ... but here, she realised, was an idea worth having. And only she could have pulled it off so completely. Only she had the requisite control, the willingness to absent herself from the authorial scene and let her plot shine clear.
