BBC One's Silent Witness is back with the final two-part instalment of the season, featuring a dramatic scene where six individuals are killed in a Syrian pizza restaurant shooting. Emilia Fox's Nikki Alexander and David Caves' Jack Hodgson are tasked with identifying the shooter before they can cause further harm. A suspect is pinpointed through CCTV footage, but he is found dead, allegedly by suicide, using the same distinctive bullets used in the attack. The first part of this gripping tale airs tonight, February 3, with the season finale following on February 4 at 9pm.

The regular cast, including new additions Harriet (Maggie Steed) and Kit (Francesca Mills), will return. Amidst solving another perplexing case, Nikki finds time to browse for wedding dresses.
