In "The Stolen Bacillus," the threat of terrorism is an important theme. We see this through the character of the Anarchist who uses deception to gain entrance into the Bacteriologist's laboratory. The purpose of his visit is to obtain the cholera bacillus which he will then use to wreak havoc on the streets of London. While Wells does not reveal the specific political motivations of the Anarchist, it is clear that he seeks personal notoriety and long-lasting fame:
"The world should hear of him at last."
In the contemporary world, terrorism remains one of the most pressing issues for political leaders and their governments, particularly since the September 11 attacks in the U.S. in 2001. The Bacteriologist's attempt at capturing the Anarchist is, therefore, very relevant to modern times because it remains a real and constant threat.
