World Cup and Wimbledon are over so it’s finally back to regular (crime drama) programming. This week’s lineup has plenty to offer. From the return of two acclaimed British thrillers to an atmospheric French mystery and a chilling new BBC adaptation, these are the latest series worth adding to your watchlist.

The Crow Girl – Season 2 (Paramount+, 20 July 2026) The dark psychological thriller returns for a six-part second season, with Eve Myles and Katherine Kelly reprising their roles as DCI Jeanette Kilburn and psychologist Dr. Sophia Craven. Picking up immediately after the dramatic season one finale, the pair investigate the murders of young male asylum seekers, while the discovery of a mummified body hidden inside a church wall and another corpse in a freezer reveals a disturbing connection. Meanwhile, Sophia fears her unstable former patient, Victoria Burkeman (Clara Rugaard), may once again be at the centre of the mystery.

The Undeclared War – Season 2 (Channel 4, 21 July 2026) Four years after its gripping debut, Simon Pegg returns as the cyber-thriller shifts back inside GCHQ for an even bigger national security crisis. Rather than following traditional MI5 or MI6 operations, The Undeclared War offers a fresh take on modern espionage, with cyber warfare taking centre stage. Hannah Khalique-Brown and Alex Jennings also return, while Blue Lights star Siân Brooke joins the cast as political tensions rise and a dangerous new cyber threat emerges.

Sea Shadows (Channel 4, 24 July 2026) French mystery thriller Sea Shadows (Rivages) begins when a fishing boat carrying 16 crew members disappears during a violent and unexplained storm off the Normandy coast. Oceanographer Abigail, played by Fleur Geffrier (Drops of God), reluctantly returns to her hometown of Fécamp to investigate strange phenomena linked to the disappearance—only to confront painful memories from her own past. Blending crime, mystery and science fiction, the six-part series slowly builds an unsettling atmosphere as it questions whether the truth lies in nature, human intervention or something far more extraordinary.

The Rapture (BBC One, 26 July 2026, 9pm) Adapted from Liz Jensen’s bestselling novel, The Rapture stars Ruth Madeley as forensic psychologist Gabrielle Fox, who takes up a role at a high-security psychiatric hospital after a life-changing car accident. There she encounters teenage inmate Bethany Krall, played by India Amarteifio (Queen Charlotte), who was convicted of murdering her mother but claims to possess psychic abilities. Set against the backdrop of an oppressive heatwave and growing civil unrest, this five-part psychological thriller promises a compelling blend of crime investigation, psychological suspense and the supernatural.
