The Capture

Carey is under pressure to charge James Whitlock, with Pierson keen for them to work together to close the case. Both soon find they have other problems to deal with, and Whitlock is left to Latif and Tan to 'break'.

Carey's inability to reach Napier leads to her facing the consequences of her actions, and through Danny Hart, an unlikely group of allies presents itself. Pierson is also facing the consequences of his actions and must convince his colleagues that he is fit for the job.

Meanwhile, an off-the-record military group known as ‘E-Squadron' seek advice from the mysterious Simon on how to get their plans back on track. Simon suggests ‘executive action', and a deadly trap is set for Rachel Carey.

Carey and Pierson escape into a network of underground tunnels as Pierson's past comes back to haunt him. Unarmed and with no back-up, Carey has no choice but to hear Pierson's story. She is horrified by what Pierson has been through and the extent of the conspiracy that they are now both entangled in.

Simon's real identity is revealed as Carey's allies above ground piece together the truth about Pierson. Carey forges an uneasy alliance to bring down the forces truly responsible for Isaac Turner's murder.

With Pierson deemed MIA, Carey finally gains full control of SO15 and immediately releases Whitlock, leaving Figgis with no choice but to act. The Correction Inquiry hears a shocking revelation from Sir Rowan Gill, thrusting Garland into the glare of the world's media. Pierson takes the initiative and, with some help from Wizard, gets back on his feet.

E-Squadron go on the offensive, and Carey becomes entangled in an increasingly complex and dangerous situation. Every action she takes appears to have been predicted and premeditated. With few allies left to trust, sacrifice is inevitable – just how far is Rachel Carey willing to go to protect the truth?
