The Nigerian

A Nigerian conman is set up by MI6 to spy on Russia after the world's second Cullinan diamond is discovered in Moscow.

MI6 has been watching Debare Balogun's shady business deals for years and have more than enough evidence to force Nigeria to put him away for life in Kirikiri; the most notorious prison in Africa.

The Brits have one offer for the Nigerian: infiltrate Moscow and gather evidence on possibly the world's largest diamond heist that goes deep into the pockets of KGB, Federal Assembly and the Russian Mafia.

Can you count on the Nigerian to expose the plot of one of Russia's darkest mafia circles or will the Russians find out that the British are spying on them first?
