Do you know who's knocking at your door?
After a violent home invasion in the remote wilds of Glen Coe leaves a family of four dead, DCI Jack Logan and his team are brought in to lead the manhunt.
But, when one of the victims is revealed to be one half of legendary 1980s Glasgow-based comedy double act, ‘Neeps & Tatties’, Logan is forced to leave the Highlands and head back to his old stomping ground.
He may have spent his career dealing with the worst humanity has to offer, but to find out who killed Archie Tatties and his family, Logan will have to confront his most terrifying challenge yet - the seedy world of Scottish light entertainment.
