However, fans think Hooper is in for a promotion in the police station after spotting a trend.
One Reddit user said: “JP up? Surely JP is getting promoted after smashing the test hopefully he gets promoted or else he might want to move to further his career.”
One user replied: “They’ve always had two sergeants in SM, a uniform, and a detective.
“So JP will get promoted next season to replace Dwayne’s vacant position.
Another fan explained: “I always thought it was a DI, a DS, and two officers?”
Could he be in for a promotion when the show returns to BBC One?
Death In Paradise can be streamed on BBC iPlayer.
