Peter Craig is a counter-terrorism expert for the British.
As a civil servant in the Foreign and Commonwealth Office of the British government, holding the position of Overseas Police Advisor, he is a well respected authority on terrorism and insurgency around the globe. Being such, he is very much in demand as an instructor and lecturer and travels to world extensively both teaching what he has learned and learning the newest gambits by rebels and terrorists.
He got his start at least twelve years before the series begins, a young, earnest policeman, shortly out of Cambridge, made probationary Assistant Superintendent of Police in the British colony of Sierra Leone and remained at that post for several years before being promoted to Commissioner of Police for "Bangasa" (sic) until that country won its independence and he returned to England. He joined the Commonwealth Office which was a part of the Foreign Office and in that organization he was able to combine his police skills with the diplomacy he learned the hard way, coupled with a new and intense understanding of subversion and terrorism.
Craig is for the most part a non-violent man. His position with the Foreign Office is not one from which he would expect any amount of action but his fate seems to be otherwise and invariably he gets into the middle of things. He often has to show that though he does not care to fight, he is most certainly capable of it, and of winning.
He is a fairly quiet, low-keyed individual, moderate in nearly every part of his life. He has no known family but definitely has an appreciation for the fairer sex. He drinks in moderation and has no other discernable vices. Except, perhaps, for a determination to get at the truth of a case, no matter how dangerous that might be or uncomfortable the exploration.
Note: 37 years after the sixth Peter Craig adventure was published, Kenneth Benton's grandson released in e-book format a new adventure that "comes from an unpublished manuscript, posthumously edited and published".
