In 1665, plague reaches the Derbyshire lead-mining village of Eyam in a bolt of flea-infested cloth ordered from London by a tailor, George Viccars, who lodges with the widow Anna Frith and becomes the first to die. The cordon protects the surrounding towns, but roughly a third or more of the village dies inside it over a year.
When a community faces mass death it cannot explain or stop, fear turns into a hunt for someone to blame, usually whoever is already marginal. In the novel, villagers murder Anys Gowdie, a herbalist healer, and her aunt Mem as witches, even though their remedies had helped the village. Scapegoating gives a panicked group a sense of control, and it destroys the very people whose knowledge could have helped them.
A collective sacrifice can be framed as shared, but its costs usually fall on whoever cannot leave. In the novel, the gentry Bradford family flees Eyam before the cordon closes, while laborers, servants and miners stay and die to protect outsiders. Some villagers, like Anna's father Josiah Bont, turn the crisis into a business by charging the desperate to dig graves. To judge a communal virtue, look at who had the option to exit and who profited from those who didn't.
Mompellion keeps the quarantine going by preaching the plague as God's test, a framing that gives people a reason to endure what they otherwise could not. As the deaths pile up without justice or pattern, the same framing collapses into despair and self-punishment, both for him and for the believers he led. Anna moves instead toward practical, empirical healing and midwifery. The novel's claim is that meaning imposed from above can drive heroic action, but it becomes brittle once events stop fitting it.
