Attica Morgan is an agent with British Intelligence.
Since the time frame for her activities starts in 1789, there was no real official organization that she could pinpoint to as her employer. She answers to Lord Pole, "one of the most important men in English intelligence", and a man that Morgan is fairly close to, if anyone could be considered close to this cold man.
We meet Morgan in the first recorded adventure when she is about to be sold as a slave in the streets of St. Petersburg. The reigning tsar is the Empress Catherine the Great and she had years before outlawed slavery but that enlightened attitude has not oozed down to the marketplace. Morgan is in the control of the human traffickers of that time, pretending to be a Kurd, all so she can be thrown in a large cell to locate a single person; when she finds him she identifies herself as "an English spy. I'm here to rescue you".
Morgan is the sole offspring of the first marriage of Lord Morgan, a wealthy member of the English peerage, and a dusky woman of Africa who did not survive long enough to reach England but who was still adored by her grieving husband enough so her portrait hangs in the hall of the mansion he owns in King's Cross. Morgan is described as being a tall woman (by several people with different frames of references) with grey eyes and considerable beauty whose relishes her mixed blood because "I can look like many different people. I can be, say a Jewess or a Spanish dancer or an Italian heiress or a coal-eyed beggar girl. This is a great advantage for a woman who travels in disguise".
In addition to the physical traits that allow her to blend in as needed around Europe, North Africa, and the Middle East, Morgan has a keen gift with languages. She Speaks French, Russian, and Kurdish, along with who knows how many other languages. ....
As stated, she works under the stern control of her uncle, a man quite adept at, if not totally dedicated to, hatching schemes to learn things from other nations for England's benefit. Just as Morgan considers herself largely an outcast, as are all of "us in the low business of espionage", so at times does Pole - "his long nose and swarthy features are courtesy of his German father - a Bavarian count whose scandalous lineage [he] dedicates his life to nullifying. The rest of his time is spent plotting, an activity at which he is masterly".
The relationship between Pole and Morgan is an interesting one. He seems determined to show little or no kindness to her and she responds by demonstrating no reaction to his aloofness. Pole has no qualms about making use of her espionage skills though he feels she would be of much better use married to some foreign dignitary and able to spy from that vantage point. She is not so inclined. He chides her once that she was seeking to "become indispensable in the active spy network. That has been your game, has it not?" to which she replies, "It isn't a game".
