Annika Alibi, 9pm

Nicola Walker (below) is on top form again in the second episode of her latest crime drama. This time DI Annika Strandhed heads for the Isle of Bute after a body is found in a boat off its shoreline. Items left nearby suggest a jilted lover may be responsible for the murder, but the locals refuse to reveal what they know. Annika does, however, find links to Norse mythology, while her daughter Morgan is thrust into the centre of the case.
