We love the way that, once again, this classy thriller is brilliantly and realistically complex without being deliberately over-complicated – each week little bits of the jigsaw just slip cleverly into place.

While a very jittery Marion faces the consequences of her behaviour, Sara has some explaining to do to her heartbroken family as the impact of her past hits them hard and, as more shocking details about Colin’s time as a banker come to light, the blackmail threat takes a new turn.

Elsewhere, Cassie’s compassion comes to the fore as she tries to help David Walker’s troubled son Jason, but when deeply unsavoury allegations about David lead to a new line of enquiry, she has a very uncharacteristic difference of opinion with Sunny.
