The drama stars Tamsin Greig, Darren Boyd and Katherine Kelly, and involves the police investigation into the disappearance of young boy, Callum Reid.

Mark Lawson of The Guardian said of the opening episode: "This maternal parallel brings a fresh depth to the by now standard scenes in which a detective breaks bad news and O'Malley's scripts cleverly lengthen the shadow by making DCI Brand's relationship with her own young son complex and a source of concern and regret to her: it becomes increasingly clear that the title The Guilty may apply to more people than merely the killer of Callum.

The flashback is a problematic device in crime fiction because it is often used – most grievously in Agatha Christie dramatisations – to convey events that, it turns out later, never happened, but were simply the lying version of a suspect.

In The Guilty, though, the two past and present strains of narrative seem to be reliable and exist simultaneously – without any of the visual or musical clues that sometimes signal flashbacks – as they must surely do in the minds of bereaved parents.

In The Guilty, the latter aspect underlines the mother-mother storyline, while the former brings an unease to the routine police scenes through the suggestion that soft-voiced compassion or encouragement of colleagues is something at which DCI Brand has to work.
