Purefoy, who plays a serial killer with a difference, called Joe Carroll, has been a closet Yeovil Town fan for many years and lives locally in the area.
Reports suggest that last night's episode had the highest single audience figure for the first episode of a crime series.
It's a bit grisly with lots of blood but as pure entertainment it is excellent and worth a watch. Whether he gets any mentions of the Glovers into the dialogue though is thought unlikely!!
