black man runs tower block gets killed young child takes over

A veteran beat cop and teenage girl fall to their deaths from a tower block in south-east London, leaving a five-year-old boy and rookie police officer Lizzie Griffiths on the roof, only for them to go missing. Detective Sergeant Sarah Collins is drafted in to investigate, working to find Lizzie before she comes to serious harm, but also to uncover the truth behind the grisly tower block deaths.

A father takes justice into his own hands when he thinks his son has been sexually assaulted. A suspected paedophile lies dead outside a block of high-rise council flats. Did he jump or was he pushed, roles are reversed as the hunter becomes the hunted.
