Agent Shade

Agent Shade is an intelligence agent with the Mystery Trackers investigative organization, and their agent liaison for the Detectives United.

Biography
Very little has been revealed about Agent Shade. The Mystery Trackers installment Silent Hollow describes her as being the organization's main intelligence conduit, and "as deadly as she is beautiful." The same game notes that she is an active ops agent whose role is "intelligence and safety management," and has special skills concerning "control over multiple and diverse resources."

Like most Mystery Trackers field agents, Agent Shade uses a code name for her work. Her real name is unknown. When the Queen calls for help in Origins, she addresses the agent as "Miss Shade."

In the Detectives United series, she takes on the role of mission control, providing the three detectives with information about their cases and the means to remain in contact with each other while in the field. She is the group's primary form of contact with clients. In Origins, she dispatches Agent Brown to respond to the Queen's request for help, provides him and James with transport to the Black Swan Clinic, and - at the end of the adventure - proposes the group name and distributes membership badges to the three detectives. At the end of Darkest Shrine, she's the one to present the detectives with medals for their heroism.

Her role in the games beyond this has been minimal. She is attacked during the events of Origins, when the Collector invades the Mystery Trackers headquarters in search of the stone known as Azazel; he doesn't hurt her, but she's left shaken by the experience. In Darkest Shrine, she coordinates the efforts of the detectives as they split up and head to different parts of the world. Her participation in both Timeless Voyage and Phantoms of the Past is extremely brief, owing to the nature of the plot. She barely participates in Deadly Debt at all, other than as a point of contact between the three detectives; she doesn't even appear in the game except in conversations on the telephone.

James Blackthorne
There is a slight implication that Agent Shade is acquainted with James prior to the events of Origins. He explains that he was the one who helped the Mystery Trackers develop the technology for their field communications device, and since she's their top intelligence agent, it stands to reason that they would have worked together on this project. We don't see much interaction between them, but their communications are always polite and friendly.

Anna Gray
The two women of the team have few interactions onscreen, but they obviously know of and appreciate one another's skills and abilities. Agent Shade knows that Anna can get things done, and when James needs help during the events of Darkest Shrine, she calls on the time traveler to go to his aid.

Dorian Brown
Brown and Shade are both field agents for the Mystery Trackers, and have long been acquainted with each other. There is clearly mutual respect present in their relationship; when the Queen first calls Shade with a problem in Origins, she immediately knows that Brown is the perfect choice for the case, and Brown is grateful to her for the consideration. Their onscreen interactions are limited thus far, but he is always seen to treat her cordially. Notably, in Phantoms of the Past, she is the only one in whom he confided that he was going on his secret mission, and he entrusted her to pass on his case notes to his partners if he didn't return. When she finally breaks the news to James and Anna that she hasn't heard from Brown in two months, her usual calm demeanor is somewhat jostled by palpable concern for his well-being. In Deadly Debt he calls her with the first update about his investigation into the back alley location where he has detected paranormal activity, and she urges him to please be careful, once again showing that she genuinely cares about his welfare.

Trivia

 * Like Agent Brown, Agent Shade is not the player character in the Mystery Trackers series. However, she is seen (unconscious) in the fifth installment, Silent Hollow, which gives the player some of her dossier. She is a significant figure in the installments The Winterpoint Tragedy and Fatal Lesson, the latter of which reveals that she is actually the player character's best friend.
 * According to her identification badge in The Winterpoint Tragedy, Shade's first initial is M and her date of birth is July 25, 1989. Her personnel dossier seen in the DU game Deadly Debt gives her age as 23 years old; combined with that date of birth, this would suggest that the DU games take place in the early 2000s.
 * The dossier in Deadly Debt states that in addition to being the Mystery Trackers' contact agent for the Detectives United, she also serves as the DU's psychologist.
 * Most field agents in the Mystery Trackers have companion animals who assist them in their investigations. According to the profile of Shade seen in the installment Silent Hollow, her companion is a pyrokinetic vulpine called Firefox.
 * Courtney Christine Rosemont, who voices Agent Shade, is also the voice of Anastasia Smith, the flower seller in Phantoms of the Past.
