In The Guardian, Lucy Mangan praised the series not focusing on the perpetrator: "the attention is on the women. Specifically, the living women. And, when they are gone, the people they leave behind."^[9] She also says: "We have come to expect virulent misogyny and racism to be on show in dramas set in earlier decades and involving the police – or any other unwieldy, male-dominated institution – but The Long Shadow succeeds in embedding it more quietly but firmly. It is a way of life, a way of thinking rather than a succession of big instances."
