Searching for the truth Happy Valley

(BBC1, 9pm-10pm)

This new drama from the pen of Sally Wainwright features a fantastic cast, which includes Sarah Lancashire, Steve Pemberton and Joe Armstrong.

Catherine Cawood is the sergeant on duty when accountant Kevin Weatherill enters her police station to report a crime – the kidnapping of his boss’s daughter.

Although he originally came up with the plan as a way of paying for his children’s private education, he eventually backed out. However, his partner is dangerous local drug kingpin Ashley Cowgill –and he has gone ahead with the plot anyway.

The case hits a nerve for Catherine, who has lost her own daughter and is determined to bring the captors to justice.
