Query: O'Reilly Rules!

I've stumbled across "Games of the Hangman" by accident and was hooked by the non-stop action. Now 5 years later, I stumbled across "Rules of the Hunt" and am enjoying, once again the very dangerous adventures of Hugo Fitzduane. Indeed looking forward to reading the "Devil's Footprint" (look for my review). Mr. O'Reilly's prose is straightforward and clear with a very tight plot. The characters come to life and the action sizzles. Not for the weak of heart. Terrorism is a very real threat that Mr. O'Reilly brings to light in all it's dark reality.
