The Masked Singer, STV, 7pm

THIS series, in which celebrities sing while wearing fancy dress which hides their identities, has certainly divided opinion.

While some critics have said it could signal the death knell for Saturday night singing contests, the public (well, some of them) appear to have bought in to the bizarre talent show, which is based on the smash-hit South Korean series.

Joel Dommett is back tonight to host episode four, with the identity of the third celeb revealed at the end of the show. Singer Rita Ora, broadcasters Jonathan Ross and Davina McCall, and actor Ken Jeong join in the fun as they attempt to solve the mystery of who is disguised as a daisy, a fox, an octopus, a tree and a monster.

Tony Robinson’s History of Britain, C5, 8pm

FOR a generation growing up during the 1980s, Tony Robinson was synonymous with Blackadder. Series three was set during the Georgian era, and gave writers Ben Elton and Richard Curtis a chance to send up the period, but what was it really like?

In this week’s show, the actor explores the lives of people from that era, including the stories of gin entrepreneur Elizabeth Bowman, who fell foul of the law when her enterprise was made illegal, and coach driver Jack Rann, who became a highwayman.

Wisting, BBC Four, 9pm; 9:45pm

THE penultimate double-bill from the Norway-set crime drama sees William suspended, leaving him unable to protect his reputation or officially investigate the supposedly wrongful conviction.

Is there a killer still on the loose because of what he did 17 years ago?

While the rest of the team are determined to clear Wisting’s name, the question remains: if he didn’t tamper with the evidence, who did?

Then, in the second episode, a young woman who wanted Benjamin to file a complaint about her stalker is reported missing.
