The shop owner Adolf Verloc, member of an anarchist group and secret agent for a foreign government, is summoned to meet Mr Vladimir, the country’s ambassador, who asks him to carry out a terrorist attack at a famous London landmark. Verloc has misgivings, but Mr Vladimir knows how to make people do what he wants, and when the plan goes wrong, it is Verloc – as well as his young wife, Winnie – who must deal with the consequences.

A story of espionage, intrigue and corruption based on a real-life attempted terrorist attack in Victorian London, The Secret Agent was one of literature’s first political thrillers, and is widely considered to be among Conrad’s most compelling works.
