Reception The Times described the series as a "joyous and enthusiastic celebration of classic British crime fiction" with "twisty, multilayered, multi-timelined set of mysteries that revel in just about every tradition, trope, and custom". The Guardian said that the "amateur sleuth is a well-worn archetype but Lesley Manville inhabits it more persuasively than most". The Daily Telegraph gave a less positive review, saying that it is "a clever work of metafiction, and while that might have made for a satisfying book, in a TV series it’s hard work."
