A cancer specialist and the team's resident doctor and lead scientist, Angie Marsh became involved in the organisation when her husband Robert, a prominent medical researcher, was approached to be recruited into the organisation. Robert killed himself and one of their daughters in order to prevent being converted by the vampires.

In the fifth episode of the series, she meets a vampire acquaintance of her deceased husband who tells her that he never stopped loving her, even after his death.
