Blood, 9.00pm, Virgin Media One

The great Adrian Dunbar is best known these days for his superb performances as Superintendent Hastings in BBC One's Line of Duty – but here he is starring in Virgin Media One's new six-part family drama.

The story centres on the Hogan family. After the sudden death of her mother, the Dublin-based youngest daughter Cat (Carolina Main) returns to her rural family home and soon begins to suspect her father Jim (Dunbar) may have been involved in her mother's demise.

Blood is full of twists and turns, and is sure to provide a few watercooler moments over the coming weeks. I've seen the first two episodes and it's riveting.
