Shadow kill / Chris Ryan.

Held up by rebel forces in a brutal siege, John Porter is tested to the limit in the African jungle. Strikeback hero John Porter is sent on a mission with Regimental scallywag John Bald. Where Porter plays it by the book, Bald will always want to break the rules. They are sent to Sierra Leone to extract Ronald Soames, a former CO of the Regiment and now right-hand man to the President. But when Porter and Bald arrive the Englishman has disappeared, leaving a trail of destruction in his wake. Rebels are threatening to take over the country and its diamond mines - and to massacre all foreigners. Porter and Bald find themselves fighting shoulder to shoulder with the Regiment psychopath who is already embedded in the country. But it soon becomes clear that the Firm has lied to them about the true nature of the mission. What seems at first to be a battle to control Sierra Leone's diamond mines will turn out to about a much greater evil - and with a trail that leads back to both Westminster and the Kremlin.
