September 1940 In London, a high-level British Agent is found murdered in a safe house known only to the Intelligence service-the clues lead to a mysterious order of assassins, a list of targets-and to Mason Wright.
Frank Sully Sullivan, an American working for British Intelligence, is responsible for finding the person who murdered his friend.
Unsure of Mason's involvement, he wonders if he is the man responsible, or the group's next victim.
Sully is just going to have to trust.
