INSPECTOR GEORGE GENTLY

BBC One, Sunday, 8.30pm

THE North-East, 1970. On the brink of retirement, DCI Gently investigates a body found in a chemical waste tank.

When Gently discovers the victim’s wife was convicted of his murder eight years ago, he decides to reopen the case – a controversial move.

But DI Bacchus opposes Gently’s decision, not least because he worked as a DS on the original investigation – putting mentor and protege at complete odds.
