Always Sherlock for me, although if we are talking about TV adaptations I really enjoyed Elementary too. The books are still favourites. Agatha Christie books (but only Poirot with David Suchet and Miss Marple with Joan Hickson).

I’ve just started reading the Harry Bosch books. The first one was good. I’ve not seen the TV series.

I liked the Campion series with Peter Davison.

Cost murder mysteries not so much for me.
