Lusitania and Mauretania were built at Clydebank and Newcastle respectively. They were to become the most famous liners of the Edwardian era, holding the Blue Riband of the Atlantic between them. Built for speed, they surpassed all others on the Atlantic. Janette McCutcheon tells the story of both ships. The Lusitania was lost to a German torpedo in 1915 and the Mauretania was scrapped in 1935 after a long and successful career.
