"Woodwalton Fen nature reserve is a buzzing oasis surrounded by agribusiness. Radio 4 in my studio stops me from being impatient, lets me keep fiddling with the bits Ìýthat aren’t going right. On a big task where I want so much detail, periods of being dispirited or just plain exhausted make it tempting to leave the room, which one does not do in the middle of a good play. So hurrah for Listen Again, which enables me to stay glued to the easel with dramas and all the episodes of Book of the Week or Bedtime."
