Adam Chin is an agent with the State Department's Bureau of Intelligence.
That hardly does him justice. When we first meet him, he is the Director of Asia Operations for the Department and he has been around enough and seen enough that his opinion "carried some weight around the Building, even with the Secretary". With that title and prestige it would be easy to assume that he sat a big desk and directed underlings but Chin prefers to see things himself and that means getting out into the field and putting his neck on the line.
Being in the line of fire is something that Chin seems not only good at but quite experienced with. Despite working for a Cabinet Department geared towards diplomacy rather than conflict, Chin's desire for first hand information invariably puts him in places where countries are doing things they would rather no one knew about it and if someone like Chin should die of a car accident or a mugging or just vanish, a lot of shoulders would be shrugged and no one the wiser.
Luckily for Chin, he is very good at survival and has done so for some years. His instincts are sharp and usually right. His ability to judge a situation first rate. His skills at taking care of himself are quite honed. One particularly interesting talent that Chin has is an expertise with a throwing knife and he makes it a point to never go into the field without it, which is good because it saves his life more than once.
For both adventures that exist so far, Chin will be partnered with Colonel Supriya Lal, an experienced operative in India's Defense Intelligence Agency. Described as "tall, slender, with long raven-colored hair", Lal is a beauty that stuns Chin when he first meets her. He has the decency to admit to her his having a "dropped chin" upon meeting, to which she gave a laugh that endeared her to him even more. As Chin will discover to his liking, Lal did not get to where she is through looks alone - she is a very smart and resourceful and practically fearless individual in the field and has Chin's back all the way, expecting him to have hers as well.
