Ghost map. How the most terrible epidemic of cholera in Victorian London changed science, cities

Summer 1854. London is becoming one of the first modern cities in the world. But without the infrastructure - garbage removal, clean water, sewage - necessary to support the fast -growing population, a huge city has become an ideal place for a terrible disease, before which all scientists and doctors were unsolved. As cholera begins the outbreak, the main characters of the book are investigating and ultimately decide the most urgent medical riddle of their time.
