Whilst investigating what appears to be the routine death of a hacker in London, mismatched detectives Charlie Hicks and Elaine Renko stumble upon proof that, due to a mysterious cosmic event, the world is facing certain destruction in five years – a fact the powers-that-be would very much like to keep under wraps.
Unruly police detective DCI Charlie Hicks is deeply suspicious of his new partner DI Elaine Renko. But their first investigation exposes a secret that will connect them for life.
The murder of a jogger has dire personal implications for Renko but she pretends it is a routine investigation. Hicks makes a startling revelation about the Alex Butler murder.
Renko persuades a newspaper to publish the Hard Sun dossier. The government shuts down the story but the detectives investigate a killer for whom the 'Hard Sun hoax' is very real.
