Margerie Olsom

Margerie Olsom is a Conspiracy assassin and Renfield. Little is known about Olsom, as she was encountered only once and her given name and identity were obvious forgeries.

Actions of the Agents
Samuel Black encountered Olsom on the flight from Norfolk, Virginia to Dubai during the agents' investigation into AgriWealth and the kidnapping of Owen Altone. Olsom was one of two assassins sent to kill the agents aboard the flight, though Bellamy Rook was not present, having taken a separate flight routed through Kazakhstan at the behest of Black.

Olsom presented abilities now known to be typical of Renfields, including increased strength and agility, as well as extreme resistance to pain and supernaturally fast healing.

While Olsom was defeated in combat by Agent Black, he did not elect to kill her, leaving both her and the other Renfield assassin, John Tourling, incapacitated on the plane when it arrived in London, England.
