Hard Sun

DCI Charlie Hicks, a malcontent police detective, grows suspicious of his new partner, DI Elaine Renko; their first investigation into what appears to be a straightforward case of suicide exposes a state secret that connects them for life.

Renko persuades a journalist to publish the Hard Sun dossier, instantly rendering her a target for Secret Services.

Renko investigates evidence that suggests Hicks and Butler were corrupt; a disillusioned former aid worker who believes the truth about Hard Sun wants to challenge God into revealing himself by targeting helpful people; Grace makes Hicks an offer.

London is under siege as the scale and bloodiness of Blackwood's killing escalates; Father Dennis becomes a public pariah; Hicks deduces where Renko has hidden the Hard Sun flash drive; Grace leaves Daniel with shocking information about his father.

The murder of a night jogger has dire personal implications for Renko and Daniel, and only Hicks and Renko understand the significance of his death; Daniel inadvertently discovers the Hard Sun flash drive, which puts him in Grace's crosshairs.

Tired of operating defensively, Hicks and Renko take the fight to Grace's door; DCS Bell arrests Grace and brings her in for questioning, but she will not remain outmaneuvered; Hicks, Renko and Grace's enmity culminates in a bloody dawn climax.
