Sam Garner

Detective Sam Garner was paid by Grayle to investigate Winter Quay, which was a building infested with Weeping Angels. Not realising this, he walked into a room labelled by his own name. He discovered an identity card identical to his, and then a man in a bed, claiming to be him. He ran out of the room, and tried to escape, but found that Angels were barring his way and so he was caught and sent back in time. (TV:  The Angels Take Manhattan)
