Trevor Dobie

 is a builder in the British reality show "The Murder Game" (based on the short-lived American reality show, Murder In Small Town X).

He was labeled as one of the nine suspects of a killer who murdered Catherine Prior. As it came down to him and Jay Wilmington, it turns out that Trevor is the killer.

He murdered Catherine because he wanted to have custody of Catherine's daughter, Anya who also turns out be Trevor's daughter. Even though Catherine admitted that Trevor is Anya's father, she refused to give her up and threatened to leave the town of Blackwater. Furious, Trevor attacked Catherine. She tried to defend herself with the navigational dividers, but Trevor grabbed them away and used them to stab her.

In challenging the contestants to a game, he also "killed" 9 of them. And for reasons unknown, he also murdered Tina Wells.

Andrew Weaver survived Trevor's final game and relayed the police department to arrest Trevor Dobie for Catherine's murder.
