Next of Kin

GP Mona Harcourt hears that her brother, Kareem, has been kidnapped on his way home to the U.K. for his charity clinic in Lahore. It all unravels on the same day that a terrorist attack brings London to a standstill.

After contacting Danny in Pakistan, Mona heads to Lahore to identify Kareem's body. The trip provides her a chance to make contact with Danny but also leads her into danger.

Despite her injuries, Mona heads back to the U.K. intending to investigate Danny's potential links to radical Islam. Her attempts to get Danny to safety on the day of Kareem's funeral results in unexpected consequences for the family.

After Mona is released from custody, she agrees to help police bring in Danny. The outcome of her actions at home is devastating, with her marriage almost at tipping point.

Omar attempts to step in and rescue Danny, but he puts the entire counterterrorism operation in danger; with the terror cell compromised and off the grid, the police's trust in Danny is severely compromised.

Barnes and the counterterrorism unit face a race against time to foil the imminent terror attacks while Mona and Danny are still trapped within the terror cell.
