I was so sure I’d finally outwitted Agatha Christie with this one – I had my theory, my suspect, my smug little smile – but nope, she absolutely floored me again. The way she twists the story just when you think you’ve got it all figured out is nothing short of genius.

The structure is so clever, with Poirot piecing together a murder from five different perspectives. It’s like a literary jigsaw puzzle, and every piece seems to fit perfectly... until you realise it doesn’t. The characters are so vivid, each one pulling you further into the mystery.

I thought I’d finally outsmarted the Queen of Crime, but she pulled the rug out from under me in the most brilliant way. If you think you’ve read Christie’s best, this one will prove you wrong. An absolute gem!
