While visiting Marathon, Greece, Lord Muncaster of Britain is kidnapped by brigands, almost resulting in war. The pirates, led by Takos Arvanitakis, were experienced in kidnapping and had used it as a lucrative source of income for many years. However, their capture of Lord Muncaster and a group of English tourists proved to be more difficult to pull off than they anticipated.
Arvanitakis and his gang demanded £50,000 for the release of the captives. King George of Greece refused their ransom demands, offering instead to exchange himself for the hostages in an attempt to appease England. However, before any further negotiations could take place, a confrontation between the brigands and Greek troops resulted in the death of just about everyone involved, including Muncaster. Arvanitakis was one of the few who managed to escape the battle with his life.
The incident caused England to threaten war, but Russia interjected by siding with Greece. The crisis was averted after Greece conducted a major crackdown on the bandits. Although few of the people they arrested had actually played any role in the kidnapping, it eased the international tensions and greatly reduced the number of subsequent kidnappings in the country.
Arvanitakis was shot and killed two years later.
