Patrick Chambers is a freelance agent.
He certainly took an unusual route to such an unusual profession and even agent is not his official, intended occupation. That line of work involves plants.
Chambers is an impressive man both physically and professionally. At 37 years old when the series begins, he stands 6'4” tall and has a wide, muscular build making him very imposing when first met. He is handsome and charming and has a relaxed air about him that makes people open up to him often without realizing it.
His intended line of work was that of academic administration and it was for that he earned his degree and was offered at job at the prestigious Johns Hopkins University. His climb up the ladder was fast and furious and at the age of 32 he was made the youngest dean of a department the school had yet had. He stayed for three years at that position until the hassles of academic bureaucracy got to him and he quit.
Falling to his great love of growing things, Chambers bought a plant store in the middle of Georgetown called Green-Space Unlimited, a firm that specializes in providing plants and such for offices buildings and environs in and round the nation's capital. He is considered an expert in tropical plants and has been asked to speak and advise on the matter.
The last bit of information about Chambers that is of import is that he also has earned a reputation over the years as a skilled criminologist, a man who is able to sniff out clues that others miss, put the pieces together quickly and quietly, and come to an understanding faster than most. Additionally, his administration skills, combined with his criminology skills, make him a recognized expert at setting up police procedures and organization. It is these skills that are used by various groups over the years, all on a freelance basis for a standard fee of $5000 a job.
Those who have contracted with him for his services have included the CIA, the State Department, and the White House. Outside the American government one of his clients has been the Organization of American States, with the White House's endorsement.
