Nicolette Jones's book is brilliantly researched and entertainingly written. It tells the story of how the formidable George Plimsoll campaigned to regulate merchant shipping in the late 19th century, eventually giving his name to the load-line that appears on all ships today. On the face of it not a promising subject but Plimsoll is a larger than life character, who more or less invented the single-issue campaign. The ship-owners who opposed him are the epitome of moustache-twirling Victorian villainy. As a matter of course they would despatch over-loaded and over-insured "coffin ships", confident that they'd turn a profit whether or not the ship reached its detsination. The book goes to the heart of the Victorian debate about free trade and social responsibility. It has great insights into the attitudes, social history and the politics of the age.
And it explains how plimsolls (the rubber-soled gym shoe that we all wore in the Jurassic era before trainers were invented) got their name. Highly recommended.
