Touching Evil: Series 3

Fighting deranged criminals and their own post-traumatic stress, Dave Creegan (Robson Green), Susan Taylor (Nicola Walker), Mark Rivers (Shaun Dingwall) and new recruit Martin Simmons (Andrew Scarborough) make up London's Organized and Serial Crime Unit in the third season of the British crime drama. They're hot on the trail of a serial killer who removes the hearts from his targets and a murderer who immolates each victim in a purifying bonfire.
