Agatha Christie’s Complete Secret Notebooks - Agatha Christie, John Curran, David Suchet

Endless Night is Agatha Christie’s final triumph, her last great novel and the greatest achievement of her last quarter century. It is written by an elderly upper middle class woman in the voice of a young working class male; it recycles her most famous trick forty years after she originated it; it is totally unlike anything else she ever wrote; and finally, it is a return to the multiple death scenarios of And Then There Were None and Death Comes as the End.

Endless Night really is a cracking read. It also appears that Curran's taste in Christie novels is quite close to mine.
