Could you recommend me a really clever mystery book?

[samalama]

Everyone I know is either off on holiday for the bank holiday weekend or having BBQs or going on days out, but I'm alone and with no one to make plans with. So I thought I'll get myself lots of ice cream and chocolates and do some reading over the weekend.

Does anyone have any recs for a nice mystery book with some very clever detection? Either all the clues line up so nicely or the one big clue at the end makes everything clear and is very satisfying. I've read the Richard Osman ones and they don't fit the bill. I like Agatha Christie and Conan Doyle but I've read most of theirs. Still, any recommendations welcome, either old or new books.

Thank you so much for the recommendations. I'm going to work my way through these but I'm reading Janice Hallett at the moment (The Twyford Code) and it's exactly what I was looking for!

Thank you, found the first book in a charity shop yesterday after seeing your post! Going to take it on holiday 😊

Thank you for the recommendation. I'm now listening to The Defense on Audible 🎉

And what will we do when the series is over 😱 I hope she writes a new series of some sort 🤞🏻

Might be more thriller than mystery but I think the Washington Poe series by MW Craven is brilliant
