Drama: Silent Witness, 9pm, BBC1

The storyline that started last week comes to an end tonight and Nikki (Emilia Fox, right) reaches out to Becky in order to help her deal with mounting woes as her father finds himself implicated in the killings. The death of a schoolteacher proves key to unravelling the mystery, while Jack’s paranoia about Clarissa leaving deepens further when the pair team up with Max. Sadly, just two more episodes remain in the series after tonight.
