To have listened to Radio 4’s marathon ten-hour adaptation of Tolstoy’s War and Peace as it was being broadcast on New Year’s Day must have been both wonderful and a bit weird. Like soaking in an ever-replenishing warm bath, indulgent, luxuriant, all-absorbing. Yet at the same time I imagine it was quite hard by the end to step back into your own world after being so taken over by the fictional cares of the Rostov, Bolkonsky and Bezukhov families.
