The Mercenary River
No city can survive without water, and lots of it. Today we take the stuff for granted: turn a tap and it gushes out. But it wasn't always so. For centuries London, one of the largest and richest cities in the world, struggled to supply its citizens with reliable, clean water. 'The Mercenary River' tells the story of that struggle from the Middle Ages to the present day. Based on new research, it tells a tale of remarkable technological, scientific and organisational breakthroughs; but also a story of greed and complacency, high finance and low politics.
