What…On….Earth. Agatha Christie is an absolute genius and that ending has absolutely floored me. It was so clever and unexpected and has hugely elevated my opinion on ‘The Murder of Roger Ackroyd’. The book concerns the event of the title, though interestingly is narrated not by Poirot but Dr Sheppard who serves as a ‘Watson’ figure to Poirot. 

The characterisation of the protagonist did feel a little weak at times (though this did have a purpose) and also the cast of characters felt a little large and at places hard to follow, but the key to the murder mystery being the twist was perfection and really hinges the entirety of my review and the opinion on this book. Not to mention I finished it in a day which says a fair amount about the merit of this book!
