What Books Feature Famous Detectives In Books With Chilling Cold Cases?

The absolute classic that comes to mind has to be 'The Hound of the Baskervilles'. Doyle’s Sherlock Holmes is just the blueprint, isn’t he? That cold, logical reasoning paired with the bizarre, almost gothic atmosphere of the moors creates a perfect storm. The image of Holmes and Watson with their lanterns, hunting for spectral hounds, is burned into my brain. It's a mystery that manages to feel like a supernatural horror story before the rational explanation clicks into place, which I think a lot of modern 'cozy' mysteries have lost sight of. The detective’s brilliance feels earned because the puzzle is so good. For a different flavor, Christie’s Hercule Poirot in 'Murder on the Orient Express' is pure, elegant deduction theater. The closed circle of suspects on a snowbound train is a trope she basically invented, and Poirot’s little grey cells working through everyone’s perfect alibi is a masterclass in structure. Miss Marple is also iconic, but she's a quieter force, often underestimated. Her village wisdom cutting through upper-class pretension in 'The Murder at the Vicarage' hits a different, wonderfully subversive note. I’d argue these are less about the puzzle-box and more about the keen, almost anthropological observation of human behavior that the detectives embody.

Interesting topic. I don't have a specific recommendation right now, but I'm definitely following this thread. The way people talk about these books makes me want to try one. Are they usually super depressing, or is there a satisfying feeling when they solve it?
