BBC One’s crime comedy Death Valley is back for a hotly anticipated second series, and a whole lot of new ‘whodunnits’ that need to be solved
Death Valley has made its eagerly awaited return for a second series.
BAFTA-winning performer Timothy Spall stars alongside Gwyneth Keyworth in the comedic murder-mystery programme, portraying the improbable pairing of actor John Chapel, formerly her hero as TV detective Caesar, and determined detective Janie Mallowan.
Filmed and set in Wales, Death Valley’s debut series launched in May 2025, smashing records with the largest overnight viewership for a new scripted programme in five years.
The series maintained a robust average of 4.6 million viewers over 28 days, and amongst Welsh audiences, Death Valley claimed the top comedy spot across all channels and platforms throughout 2025.
Given the programme’s triumph, it came as little shock when plans for a second series were swiftly revealed, with Death Valley series two now scheduled to debut on Sunday, 17 May at 8:15pm on BBC One. Audiences can also stream the complete box set on iPlayer from the same date, reports the Express.
The second series resumes several months following the conclusion of series one. Janie has secured promotion to Detective Inspector and finds herself more overwhelmed than ever, with administrative duties mounting faster than she can manage them.
Complicating matters further, she’s been avoiding John since discovering he’s been romantically involved with her mum, Yvonne (Melanie Walters), and the pair are compelled to make amends when DCI Barry Clarke (Steffan Rhodri) enlists John’s assistance to crack a murder investigation.
They must set aside their complicated personal relationships when tasked with examining a suspicious death within a community service group, following the fatal plunge of one of its members from atop a crumbling castle.
The latest series of Death Valley also sees John hesitantly return to the acting world, appearing on the set of a grand Welsh fantasy television production, though another killing soon demands attention.
Additional murders occur in a seaside fishing community, at an eco-friendly commune, and within a rugby club, as John and Janie persist in delivering justice throughout the mid-Wales area.
Throughout the series, there’s also an impressive roster of guest appearances, featuring Outlander’s Mark Lewis Jones, Game of Thrones legend Owen Teale, and Killing Eve’s Alexandra Roach.
Jane Horrocks (Here We Go, Chicken Run) also appears in the programme alongside Hammed Animashaun (Black Ops, SNL UK), Alexandra Roach (Killing Eve, Bodies), Roisin Conaty (After Life, Last one Laughing), Jim Howick (Ghosts, Here we Go), Asim Chaudhry (People Just Do Nothing), Lynn Hunter (Pushers & End of the Fxx World), Rhiannon Clements (Small Prophets, Pushers), Mike Bubbins (Mammoth) and Liz Carr (Silent Witness, Good Omens).
Death Valley series 2 launches on Sunday, 17 May at 8:15pm on BBC One and iPlayer.
