Every thriller has the bad guy monologue. You know when Gold finger says to Bond,
But Mr Bond you won't see me blow up Fort Knox with my ray gun and paralyze the army or when Lex Luther says he is bad and is going to take over the world. Well...I have just written a bit of a monologue at half way in the novel. Now the object for the protagonist is to thwart (don't ya just love thwart)the plan.
And the clock is ticking of course, what else in a thriller.
