Broadchurch

ITV, 9.00PM

We’re past the midway point of the third and final series of Broadchurch and the drama is showing no sign of releasing its grip. Last week’s revelation that Cath Atwood’s (Sarah Parish) husband Jim (Mark Bazeley) was the person rape victim Trish (Julie Hesmondhalgh) slept with on the morning before the attack may not have been a huge shock, but the closing scene that saw a new victim come forward guaranteed everyone who saw it would be back on the edge of their sofa tonight. Understandably, getting to grips with this new evidence occupies much of Miller (Olivia Colman) and Hardy’s (David Tennant) attention so it is left to DC Katie Harford (Georgina Campbell) to deliver the first big jolt here when she unearths a creepy new link to an existing suspect.
