This chapter examamines representations of the mother-detective in five British crime dramas from the early 2020s: Happy Valley (BBC One, 2014–2023), Annika (Alibi/BBC, 2021-present), Before We Die (Channel 4, 2021-present), The Bay (ITV, 2019-present), and Unforgotten (ITV, 2015-present). Wilton raises questions about changing public and private gender roles, the continued association of women with motherhood, and the use of crime shows to reinforce social order and traditional forms of authority. Her intersectional analysis positions the characters within social and criminal justice structures, and measures how the series represent the interactions between their role as parents and their professional roles. Wilton evidences that while the roles of mother and detective have historically been viewed as incompatible, a more nuanced depiction of mothering and detecting is emerging. She identifies three themes: first, ‘bad’ mothers, bad cops; second, peripheral parenting; and third, maternal detectives, and demonstrates the rising centrality of motherhood to criminal investigations in contemporary British television.
