Night's Black Agents: Dracula Dossier
An operative who owed a favor
Ian Hyde-Cooke is an operative with MI5, who made his career due to assistance from Savas Osman. Osman, providing with Hyde-Cooke with names and details about suspected terror plots in England, allowed Hyde-Cooke’s career to be made in the organization.
Later, when Osman needed details on the water treatment facility, masking Carfax Abbey, Hyde-Cooke was able to allow the agents enough details to gain access, secretly.
Unfortunately, in early July, he was one of several Edom victims in the Night of the Purge.
