Natalie Blake

Natalie Blake was a private investigator and former Detective Sergeant in 2008. She had a heart condition which caused her to be sacked from the police, causing her to become a PI. She sought treatment at the Pharm for her condition and was investigating the New Eden research lab, however she was possessed by the aliens running New Eden whilst she was at the Pharm (whom New Eden were working with). She faked her own death by burning her twin sister Naomi to death in a car, to make it look like it was Natalie; she then killed Conrad Fischer, whom she was dating whilst he was making a webcast and stole Fischers laptop with the New Eden codes in it.

However, she had no idea she'd done this, due to her alien possession. She checked into the Cardiff Century Hotel and realised her actions, recording her last moments on a video hidden on her website. Soon after, she was killed in her hotel room by a Pharm assassin. (Torchwood Mission Game)
