Death in Paradise will see the return of Selwyn Patterson's (played by Don Warrington) previous replacement, Sterling Fox (Trieve Blackwood-Cambridge), in tonight's episode. Episode six of the BBC series will air tonight after it was pulled from the TV schedule last Friday.

In the previous series, Selwyn learned that he was being let go from his role as Saint Marie's Commissioner and that Sterling would replace him.

However, even though Catherine Bordey (Elizabeth Bourgine) managed to get Selwyn his job back, he decided to leave Saint Marie and went to the UK to visit his daughter.

He even made a cameo appearance in the Beyond Paradise Christmas special and in the Death in Paradise festive episode to help with a case linked to the UK.

As series 15 of Death in Paradise began, fans were thrilled to see the Commissioner back in his role; however, in an unexpected twist, he reunites with Sterling in tonight's episode.

The Commissioner and Sergeant Naomi Thomas (Shantol Jackson) travel to Antigua after Mervin Wilson (Don Gilet) gets himself into trouble.

Mervin's own brother, Solomon (Daniel Ward), kidnaps the detective in a dramatic twist. This leads his colleagues to travel to the island to help, but Sterling happens to get in their way.

"Commissioner Patterson, what an honour," Sterling said. "And DS...what is your name again?"

As Naomi began to talk, Sterling cut in, "I heard you were back. What happened?"

"Why are you here, Mr. Fox?" Selwyn asked, to which Sterling explained he was given a job in Antigua as an officer in training.

Fans were also left questioning why Sterling was back, with one writing on social media, "What is Sterling doing there?"

"Hang on, is that who replaced Selwyn when he was fired?" another asked.

While a third added, "What on earth is Sterling Fox doing back?"

Death in Paradise is available to watch on BBC iPlayer.
