Hugo Fitzduane is a travelling photo-journalist.
Putting him in as such, however, confuses the issue for, while Fitzduane does spend his time as a photo-journalist, his actions in the three-book series have little to do with his current profession and much to do with his reactions to events around him.
For many years, Fitzduane had been a member of a small but elite group of Irish Rangers, the best trained soldiers that island nation had to offer. When Ireland supplied contingents of this cadre as part of their UN obligations, Fitzduane saw considerable action in remote parts of the world. Of particular importance was as a peace keeper in the Congo during the mid 60's where he met and fell in love with a nurse only to see her killed by rebels. After he had exacted as much revenge as he could stomach, and more than he cared to remember, he quit the Special Forces and took up photography.
Even then, however, his adventurous nature couldn't keep him out of trouble as he moved from one trouble spot to another, especially in Vietnam where his actions garnered him a fair number of friends and a few enemies.
Fitzduane need not have spent his life as he chose. He could have opted for a much easier existance for he was born into considerable wealth. This included owning his own small island just off the western coast, connected to the mainland by a bridge. On this island he lived in a renovated castle, a family holding for generations.
It is on this island that events unfold that bring him back into the world of international strife. He certainly didn't seek the trouble but once it happened, he found himself unable to back away. All this is told in the first book. The remaining two books show that one's actions have consequences.
Having been a soldier and having seen action as such and as a journalist, Hugo Fitzduane is no stranger to violence. He is quite capable of returning it when forced but he is also blessed with a conscience. He takes his actions seriously, doesn't jump into trouble willfully, and doesn't back down when he knows he's right.
While he does not work for any Intelligence agency, his contacts over the years have given him a good number of friends upon whom to call. As time goes in the series, his expertise in terrorism moves him to interesting places.
