Hard Sun

DCI Charlie Hicks, a malcontent police detective, grows suspicious of his new partner. Their first investigation into what seemed to be a straightforward 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; 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.

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.

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.
