Alec Haig is a security consultant.
He is one of the very best in the business which is why over the many years he has been specializing in helping companies keep their secrets secret and keep what belongs to them theirs and generally protect the client from all the dangers that unscrupulous people can present, he has a reputation as someone not to be messed with.
In this three-book series, the adventures deal a lot with corporate shenanigans but touch continuously on international intrigue as often criminals in another country preying on a foreign multinational can use their own nation’s sovereignty to their advantage. Haig, the main character of this eponymous series, finds too often that officials from the countries he has to go to realize that while the crooks may be crooked, what they are stealing can ultimately help the host country. Where allegiances lies can sometimes be interesting.
Alec Haig has considerable clout in these books because he is, after many years of being so good at his work, a director of the huge international corporation, Instecon, and is the Head of Security, although perhaps to keep a low profile, he has the title of Head of Tech. Sales (Misc), whatever that is supposed to mean.
Haig works for a company, not a country, but the bullets shot at him and bombs headed his way and cars and planes and other vehicles sabotaged all might disagree, or at least show their impartiality as to employer. Luckily for himself, Haig is quite good at staying alive.
Too bad for him, though, that the Head of Accounts, responsible for reviewing Haig’s expense sheet very carefully, does not hold Haig in especially high regard. The unseen man or woman, heard from only through memoranda passed about that the beginning and end of most adventures, takes the attitude of “yes, you did stop xyz from happening and thus saved the company millions of dollars. Nevertheless, purchase of X for 17 pounds is not a valid expense item and thus not approved.”
Even the best agents, government or corporate, fall beneath the might of the bean counters.
