I've discovered a new author named R N Norris who writes detective crime fiction centred around St Petersburg in the late 1800s. Nothing new about that you may say, but he has taken Dostoevsky's investigator, Porfiry Petrovich, and extended his character to this new series of books. So far I have found it works really well. I'm reading the second in the series, A Vengeful Longing, at the moment.
