Tom Wilder is an agent for IPI.
That acronym stands for International Private Investigators and from the sound of it that corporation is a large one in numbers and quite large in prestige. The cases that this group handles routinely include countering global espionage leveraged against huge multi-jurisdictional companies. Many such firms learn that hard way that in the case of criminals or governmental intruders from one country attacking or stealing from a company in a different nation and often a different continent, local police forces are totally powerless and so are most national one. It took a company like IPI to gather proof of wrongdoing enough to take the matter to an international court but even more importantly to be able to take action when those courts prove ineffectual.
While I have listed his occupation as 'agent', it would have been technically accurate to have used 'private investigator' since that is what IPI's name says they are but calling him a private eye gives the impression of a lone snoop wearing out the soles of his shoes in his investigations, working out of a small office. The facilities at which Wilder works are quite a bit different and the kind of jobs that IPI calls upon him to do is such that 'agent' fits much better.
Wilder is not only one of IPI's best operatives, known for getting the job done no matter where it takes him, he is also one of IPI's directors and as such has a voice in deciding what clients IPI accepts and how far it would go in satisfying a client's wishes. Considering the experience that he brings to the firm, his voice carries a lot of weight.
Wilder is a British citizen who proudly served in the military for several years. He had been living in New York City with his wife and infant child when the wife died in the one of the Towers that were brought down on 9/11. Entrusting his then one year old daughter to his wife's sister and her husband, Wilder return to England and signed up to fight in Afghanistan.
That service would consist of becoming part of the prestigious and elite SAS. For four years his efforts in that war would make him a seasoned operative for not only succeeding in near impossible tasks but also for being more than willing to go rogue to get the job done.
After a handful of years in the service, his need to return to his ever-growing daughter pulled him from the military and took him a new job with IPI and he has served there honorably and proudly for over a decade.
