It is largely a return to form, a suitable send-off for the battling. .... Forsyth has fully assimilated the lessons of the Coen brothers and the history of the caper film, and with an ending that lets in more sentiment than the show has previously allowed, he gives Jake and Max slivers of their Scottish dreams.

Bonnar is always the standout actor in Guilt, but over the four episodes there are brilliant performances from many others. ... Although the farce went a shade too far when they were crawling through a pit of manure, its black humour remains sharp as a flick-knife.

There is plenty to like about series three. ... Bonnar is a great actor, capable of signalling half a dozen conflicting emotions simultaneously with just the tiniest flicker of facial expression (in Max’s case, one of these is almost always ‘panic’). He is a joy to watch, and Forsyth’s dialogue is a treat to hear.

Phyllis Logan is the perfect antagonist: omniscient and omnipotent in the manor she runs, with a jagged personal brittleness beginning to poke through her armour. Opposite her, Bonnar has never been better in a role that lets him display his two great strengths – hypnotic charm and snarling, desperate malevolence – at the same time. They have made Guilt’s trip around Edinburgh’s dark corners a rare thrill.
