Tonight's Guardian TV picks are led by *Love You to Death* on Channel 4, a documentary series examining the case of Lisa Hayden-Johnson, a mother from Torbay who falsely claimed her son Matthew was so severely disabled he could not walk, eat or breathe unaided. The series draws on testimony from both Matthew and Lisa to trace how this fabricated illness took hold and eventually unravelled, offering a striking account of a damaging deception.

Other highlights include the finale of *Voices of the Valleys* on Sky Arts, following Welsh male voice choirs competing at the Llangollen International Eisteddfod, and the return of Ben Miller in ITV1's *Professor T*, in which he is drawn back into a missing-person case. Channel 4's *Outback Murder Highway* investigates disappearances along Australia's Flinders Highway, while BBC Two's *Couples Therapy* continues with Dr Orna Guralnik, and film choices include Bertrand Bonello's sci-fi romance *The Beast* and Dev Patel's directorial debut *Monkey Man*.
