A great book!

Might have to check this out, thanks

I'll throw a recommendation out too, I don't know how well known it is though so forgive me if you've all read it, but check out The Chinaman by Stephen Leather.
About 10 years ago I went through a stage of reading a book per week, and this is one of the few that really stick out.

Copy/pasted review from amazon to give you the idea:

When a chinese takeaway owner looses his wife and daughter to an IRA bomb, he wants to make sure the people responsible are punished by the law. Unfortunately he is passed from pillar to post and cannot understand why the police cannot just arrest them. When all else fails he sets out on his own mission to avenge his loved ones. Using the skills he learn't whilst fighting in the jungles of Vietnam he turns his attention to the terrorists and takes on the IRA. Totally gripping and extremely well written.
