Curran's book Agatha Christie’s Secret Notebooks is now available in the UK.
For the Guardian, he selected a top ten list of Agatha Christie mysteries.

And Then There Were None (1939)Read about the other nine titles on Curran's list.
Ten people are invited to an island for the weekend. Although they all harbour a secret, they remain unsuspecting until they begin to die, one by one, until eventually … there are none. Panic ensues when the diminishing group realises that one of their own number is the killer. A perfect combination of thriller and detective story, this much-copied plot is Christie's greatest technical achievement.
