Steered by his early 20th-century Bradshaw's railway guide, Michael Portillo boldly goes to the moon by way of the Cornish Riviera Express. On the trail of an historic achievement made at the dawn of the Edwardian era, he investigates the first radio signal to be sent across the Atlantic. In Plymouth, Michael uncovers what happened to surviving crew members of the most famous ocean liner in history, the Titanic. And at Fowey, he rediscovers a lost literary figure known as Q, who immortalised the town in his novels.
