Deep in the bowels of London, a network of Victorian tunnels has carried sewage beneath the city streets for more than 150 years. But in 2017 workers discovered something strange lurking in the dark. Longer than the famous Tower Bridge and approaching the weight of a blue whale, it was a monster of strangely – and disgustingly – human origin. But would the team be able to cast it aside?
At the beginning of the 19th century, London was home to around three million people. And while this made it one of the most populous cities in the world, it also led to some rather unpleasant conditions. In fact, most of the River Thames, which flows through the city, functioned as an open sewer at the time.
