Hidden | Series 3 Preview (BBC Four)

When the body of local farmer Ifan Williams is discovered in a remote river in the middle of the North Wales countryside, DCI Cadi John and DS Owen Vaughan are called to investigate.

Cadi learns of the call whilst attending an interview for the role of DSI in Liverpool. Whilst informing the victim's wife of her husband's death, DCI John learns that there was no love lost between husband and wife.

There seems to be no motive for the murder of Ifan Williams. Neither his mother nor his wife can think of anyone who may have wanted to hurt him.

Hidden begins Saturday 19th March on BBC Four and airs Wednesdays on BBC One Wales.
