The show begins with a British agent being killed. However, before this happened, the man was able to broadcast a message--that the Minister of Defense in this African nation had just signed a secret treaty with the Chinese. When the Prime Minister of this African country is presented with this information, he doesn't believe it--but allows Drake to stay there and investigate...with utmost discretion. However, this isn't all that helpful because the incriminating document is probably locked up in a ministry safe and the Ministry of Defense seems impregnable. So, Drake decides to use his powers of persuasion to force someone in the department to assist him. In other words, he extorts this help! What's next? See this excellent episode and find out for yourself.
Drake is a bit more devious than usual here and, uncharacteristically, uses a James Bond-like gadget to extricate himself from the custody of a Chinese spy. All in all, well written and interesting.
