Dashiell Hammett and Hans Olav Lahlum

Oh my, you say, why a double post for these different books? Well, to save time. And I want to try to express how the one made me think of the other. Let's see if I can muddle through that chain of thought... I read my first Dashiell Hammett first, and after that Lahlum's pastiche based on mostly Agatha Christie, but anyway it did remind me a bit of Hammett, so I went oh, he's trying to be a bit methodical and hard-boiled like Hammett. But it's not that much alike, really. Well, apart from Lahlum's being an utter pastiche on old-fashioned crime novels. Are you with me?
