Dark Heart, 9pm, ITV

When a young nurse dies on a platform on the London Underground, DI Will ‘Staffe’ Wagstaffe (Tom Riley) is stumped as to how and why she has met her end, but an autopsy offers up a surprise. As the woman’s recent behaviour comes under scrutiny and a link emerges with a long-missing boy and also a surgeon – look out for Claire Goose as the doctor’s distressed wife – the case takes an even more sinister turn… However, the browbeaten Staffe also has troubling family matters to distract him from the macabre case as his nephew Harry gives cause for concern, which leads to another altercation between Staffe and his sister Juliette’s seriously dodgy fiancé, Paulo. Continues tomorrow. Rating: ****

Meanwhile, Chester, a saluki, has been badly wounded in a fight and needs an operation. While he’s recovering from his injuries, Paul helps the nervous fella regain his confidence, which is so successful that Chester is able to take part in a dog therapy session at a retirement home.

Keeper Niall is hoping a sibling will help troublesome Tina grow up… Meanwhile, ageing chameleon Mr Parsons, 11, has a very important date. Seven-year-old Daphne has been flown over from France to mate with him, but as female chameleons only come into season once every two years, it’s now or never for Mr Parsons, whose life expectancy is just 12… Rating: ****
