At the turn of the 20th century, London has become a haven for political exiles and anarchists. Frequent bomb threats and disturbances interrupt the lives of the city's inhabitants, who live in fear of the terrorists in their midst. One such terrorist is Verloc, a secret agent who is given the mission to strike at the heart of London's pride by blowing up the Greenwich Observatory. But his decision to drag his innocent family into the plot leads to tragic consequences.

Józef Teodor Konrad Nalecz Korzeniowski was born in the Ukraine on 3 December 1857. His parents were Polish and had both died in exile by the time Conrad was eleven. His uncle then became his guardian and looked after him in Krakow until he was sixteen when he went to sea and sailed on French and British ships. He was made British citizen in 1886 and changed his name to Joseph Conrad. In 1889 Conrad visited the Congo and his experiences there inspired Heart of Darkness. In 1894 he published his first novel, Almayer's Folly and went on to write nineteen more as well as many short stories, essays and a memoir. In 1896 he married Jessie George and they later had two sons. Conrad died on 3 August 1924.
