All the Characters from Agatha Christie's Other Novels

Alongside the 12 Marple novels and 33 Poirot novels, Agatha Christie wrote a further 21 mystery novels with some of her most famous ones including ‘And then there were none’, ‘Crooked House’, ‘Endless Night’ and ‘The Pale Horse’ – all recently adapted for television and film.

Personally, some of my favorite novels fall into these ‘other’ works and although I love Hercule Poirot and Miss Marple the protagonists in the other novels are truly excellent – a few of christie’s strongest female characters can be found in these novels such as Emily Trefusis in ‘The Sittaford Mystery’, Virginia Revel in ‘The Secret of Chimneys’ and Victoria Jones in ‘They Came to Baghdad’. The dashing Mark Easterbrook in ‘The Pale Horse’ and Luke Fitzwilliam in ‘Murder is Easy’ are also worth meeting too.

There’s plenty of variety in these novels – whilst there are thriller and espionage tales such as  ‘The Man in the Brown Suit’ and ‘Destination Unknown’ and the Beresford novels ‘N or M?’ and ‘The Secret Adversary’, you also get ‘Crooked House’ displaying one of the best dysfunctional families created by Christie for a perfect closed circle who’done’it. Finally, ‘Death Comes at the End’ is the only novel set in another time, 2000MB Ancient Egypt. 

So if you’ve read all the Poirot and Marple novels and want something new or are interested in reading some of Christies best works – take a look at the list below. Full Character lists are included for each one. Click here to find out more about each mystery novel too.
