Agent Craigie faces a crisis of international proportions after an attempted assassination of a Russian diplomat at a top-level international conference in London threatens negotiations. Craigie and the Department Z team must work to ensure the safety of all the delegates whilst investigating the attack. It soon becomes increasingly obvious that the attack they’re dealing with was run by a highly professional organisation and they’re starting to feel out of their depth.

Will Department Z be able to match wits with bullets as they attempt to take down the assassins? How will they negotiate the political minefield where one false step could lead to worldwide disaster?

The League of Dark Men is the 23rd novel in the Department Z series, and was originally published in 1947.
