In a House of Lies by Ian Rankin
Private investigator Stuart Bloom was missing, presumed dead. Until now. His body is discovered in an abandoned car – in an area that had already been searched…Detective Inspector Siobhan Clarke combs through the mistakes of the original investigation. After a decade without answers, it’s time for the truth. But it seems everyone involved with the case is hiding something. None more so than Siobhan’s own mentor: former detective John Rebus.
