I would like to nominate The Four Just Men by Edgar Wallace.
Quote:
"The Four Just Men", first published in 1905, was the novel that made Edgar Wallace famous as a writer of detective thrillers. A Spanish resistance leader's safety in England is threatened by the passage through Parliament of the Aliens Extradition Bill. The minister responsible receives a message from four mysterious figures, "The Four Just Men", warning him that he faces death unless he withdraws the legislation. Edgar Wallace maintains the suspense and excitement as the police struggle to protect the minister before the deadline imposed by the conspirators is reached.

Day of the Jackal is probably its closest modern (1971) counterpart.
Is it a classic? It is 100 years old, and still an enjoyable read.
