I kept looking at McCarthy last night and something kept niggling at me.....something about his face.....didn't quite look right, much thinner. Looking at other pictures of him and his face IS fuller. Also his forehead is VERY shiny in the picture of him from last night - mask? Bet he's been replaced and "real" McCarthy in witness protection since DS now thinks he has "changed sides!" Don't know....maybe just the lighting, camera angles, sweating or perhaps this squirrel has gotten into a bad batch of acorns!
