And then there's the middlebrow mysteries, where the detective ruminates. Donna Leon's Brunetti series, set in Venice, resembles Louise Penny's Gamache series, set in Quebec in featuring philosophical uxorious detectives amid lots of food & local color. Nothing too hardboiled although there's always the risk of disaster.
And now I go home and try to keep myself from finishing the latest Leon in one go. Savor, El, savor!
