Hidden

Sat, 9pm, BBC4 (box set, iPlayer)

Welsh crime drama Hidden is back for a gripping third and final season this week, with Sian Reese-Williams reprising her role as Snowdonia cop DCI Cadi John.

As the six-part series returns, we find Cadi interviewing for a big promotion and facing a stressful house move. But she soon takes on a shocking new case when she receives a call from police colleague DS Owen Vaughan (Sion Alun Davies) to say that a body of a farmer has been discovered in a stream.
