With this sad but shocking revelation of Bowman's opioid addiction and how he’s on the verge of a withdrawal while on a mission, it sets the condition that the agent has to cope consistently to hide it from the other members of his team.
Bowman then suddenly finds himself absorbed into the Cell, a shadowy unit within the SAS, dedicated to fighting global organised crime. In a world where the Russian government is the real mob, it's the job of the Cell to defend British interests at home and abroad.
But the Russians have only just begun. When the Cell uncovers a sinister plot against a Seguma, they are quickly drawn into a deadly race against time to save the tyrant’s family in Karatandu.
After a tense and bitter battle with the rebels, Bowman and the surviving members of Cell are in for another shock - they learn that they are not told the whole truth about their mission in Karatandu. Will they fight back or walk away from the mass killings all around them?
