The Secret Agent by Joseph Conrad fits into the mystery fiction genre and was published in 1907. It is recommended for adult readers.
The Secret Agent was good but not at all what I expected. It follows the story of Adolf Verloc and his attempt to blow up the Greenwich Observatory. Verloc is a secret agent for the French Embassy in London and while he was previously invaluable to the Embassy he has grown redundant of late and was urged to do something big that would embarrass the British and give his employers the opportunity to inspire a revolution. He was told to strike at something scientific as that was the fad of the day. After much worrying and thinking upon the subject he finally decided to take some action. Nothing goes as planned leading to many deaths and the loss of everything he had. Nothing he did actually inspired a revolution.
