A new IRA has formed in the shadows under the very nose of MI5, who ignored vital intelligence from one of its controversial informants. This IRA reveals itself with a murderous first strike at the Commando Training Centre Royal Marines where 23 new recruits are killed.
Infamous MI6 interrogator Francesca Ford is recalled from Syria to turn or kill the rogue marine, who planned the attack. Ford and a 4-man team from a secret unit called the Increment execute Operation Requiem. Her objective: go to Belfast, drag this IRA back into the shadows and kill it. But when Ford arrives in Belfast, she realises this IRA is five steps ahead of her. Now she must navigate a dark web of informants, agent handlers and undercover operatives whilst being hunted herself by the IRA through the streets of Belfast.
When Ford's operation conflicts with a non-state sanctioned Black op called Kaleidoscope, she lures out a shadowy informant, Codenamed Ajax who gives her a chilling warning. She is being hunted. When Ford is kidnapped, only by exposing his cover can Ajax save her, but will he? But, Behind Those Eyes, everyone has a secret.
