Without Sin (ITVX) is a heavyweight thriller cut from the same cloth as Happy Valley and Save Me, so fans of deep-rooted trauma and grief rejoice, if that’s the sort of thing you do. Either way, this Nottingham-based four-parter is a very strong entry to the genre, taut and solid and compelling, and it does not outstay its welcome.

The ever watchable Vicky McClure stars as Stella, a cabby grieving for her teenage daughter Maisy, who was murdered several years earlier. As you might expect, Stella’s life has been utterly transformed by the tragedy. She has split up with her husband, Paul (Sherwood’s Perry Fitzpatrick), who is in a new relationship and who has been able to at least offer the illusion of moving forward. She has cut herself off from her social life, smokes too much weed, and gave up the office job she loved to spend long nights driving around the city dealing with drunken and difficult customers. She is in stasis, unable to do much more than simply get through the hours.
