A bomb destroys a police station near Lancaster Gate and kills officers who appear to have been selected deliberately. Thomas Pitt’s investigation meets resistance from within the Metropolitan Police, suggesting that the attack may be connected to corruption rather than indiscriminate political violence.
As Pitt and Charlotte trace the histories of the dead men, they encounter evidence of protected criminals and compromised senior officers. The case forces Special Branch to decide whether preserving public confidence matters more than exposing treachery inside law enforcement.
