The novel begins in Verloc's home, as he and his wife discuss the trivialities of everyday life, which introduces the reader to Verloc's family. Soon after, Verloc leaves to meet Mr. Vladimir, the new First Secretary in the embassy of a foreign country. Although a member of an anarchist cell, Verloc is also secretly employed by the Embassy as an agent provocateur. Vladimir informs Verloc that from reviewing his service history he is far from an exemplary model of a secret agent and, to redeem himself, must carry out an operation – the destruction of Greenwich Observatory by a bomb explosion. Vladimir explains that Britain's lax attitude to anarchism endangers his own country, and he reasons that an attack on 'science', which he claims is the current vogue amongst the public, will provide the necessary outrage for suppression. Verloc later meets with his friends, who discuss politics and law, and the notion of a communist revolution. Unbeknownst to the group, Stevie, Verloc's brother-in-law, overhears the conversation, which greatly disturbs him.
