Dennis Waterman plays Detective Sergeant George Hamilton Carter who comes from south London; in the pilot episode, Regan seeks him out because of his knowledge of the south London area. His age is given in the episode "Hit and Run" as 26. In the series' timeline, we learn that George had previously been in the Squad, but had quit for family reasons (cf. "Regan" and "Jigsaw"). George was married to Alison Carter, a schoolteacher, but is widowed in the episode "Hit and Run" when Alison is murdered by mistake by a gang of diamond smugglers. He is a former amateur boxer, as shown in the pilot "Regan", and is described as having professional boxing potential in the episode "Chalk and Cheese". Like his superior, he likes a drink (though less so than Regan), and appreciates football and—after the death of his wife—attractive women. Carter is not as potentially violent or aggressive as Regan, and usually plays the "good cop" role.
