Chekhov so dominates 19th-century Russian drama that Turgenev doesn’t get much of a look-in. His best known play, A Month in the Country, was written before Chekhov was born but Patrick Marber’s adaptation, with its new nickname, feels like Chekhov scripted by a Chekhov app. Turgenev’s characters, his atmosphere and his scenarios feel entirely familiar but they lack the tragicomic gestures that give Chekhov his unique appeal.
