Paul Baker is an agent with British Intelligence.
There is no apparent name for the department for which Baker occasionally works as this organization prides itself on its ability to send its agents to all parts of the world and have them blend in as if they were ordinary citizens going about ordinary work. It does that by largely hiring amateurs and giving them just enough training to carry out the assignment, if even that much. Certainly there are the occasional casualties as a result of this policy but its successes were good enough to keep using it.
Baker is one such pressed agents, literally snatched off the street while going about his own and his regular employer's business. He was "invited" to meet the head of the organization, Mr. Chatham. In the couple of years that Baker was involved with Mr. Chatham, he never learned if the agency had a name or designation or was even publicly admitted. He knew that the few people he worked with referred to it as The Department and that was it.
Baker knew that the headquarters for The Department was in a gray-brown building marked as an annex to the Board of Trade but he was fairly certain it was in no way connected with that ministry. Of course, it could have been because no one was bothering to tell Baker anything he did not absolutely need to know and it would seem he absolutely did not need to know much.
More seems to be expected of Baker than Baker believes is available, especially by Mr. Chatham but Baker soon learns that it is because Baker's father, a good man what Baker loved and respected, had not been the dull, average civil servant he always bemoaned he was but in fact had been the head of The Department before Mr. Chatham took the position. Since Dad had been so good at being an agent, it stood to reason that Son would be a natural. Training and experience and inclination appeared secondarily important.
Baker is by no means an inept, clueless bumbler forced into the cloak-and-dagger world. He is intelligent, curious, resourceful, and gifted with a sense of humor that comes in handy when things go wrong and despite how well the plans are made beforehand, things always go wrong. Baker survives because he can go with the flow. And there is more than a little of ol' dad in him after all.
