Wallander

9.35pm RTÉ One

The death from seemingly natural causes of one man and the apparently unrelated murder of a taxicab driver leads Wallander (Kenneth Branagh) to a conspiracy that stretches far beyond the borders of Sweden. The man’s body is found at a cash machine, the apparent victim of a heart attack. Later, two teenage girls are arrested for the brutal murder of a cab driver. The girls confess to the crime and show no remorse whatsoever. Two open-and-shut cases. At first, these two incidents seem to have nothing in common. However, the two cases become one as Wallander chases down anarchic cyber-terrorists who threaten to bring chaos and destruction to the developed world.

Life In Squares

9.00pm BBC Two

This new series dramatises the complex relationships between the members of the Bloomsbury group, a collection of friends and lovers who were pioneers of artistic and sexual freedom. Penned by Bafta award-winning writer Amanda Coe (Room at the Top), Life In Squares depicts the relationship between painter Vanessa Bell (Phoebe Fox) and her sister Virginia Woolf (Lydia Leonard) alongside Vanessa’s complicated alliance with gay artist Duncan Grant ( James Norton). We first meet the Stephen sisters in 1905. After their brother's death , Vanessa decides to change her views on marriage and settle down with Clive. Meanwhile, the young gay artist Duncan Grant forms a friendship with Vanessa which proves to be one of the most influential of his life. With their love of art and each other uniting them, but kept apart by Duncan's sexuality, can this companionship stand the test of Bohemian living?
