You do not mess with the special investigators.
The investigators are gathering evidence all the time and they've put together a package of evidence.
We do not live in a time when knowledge can be extended along a pathway smooth and free from obstacles, as at the time of the discovery of the infinitesimal calculus, and in a measure also when in the development of projective geometry obstacles were suddenly removed which, having hemmed progress for a long time, permitted a stream of investigators to pour in upon virgin soil. There is no longer any browsing along the beaten paths; and into the primeval forest only those may venture who are equipped with the sharpest tools.
. . . Prevent postal investigators from aggressively interfering with, or closing, a commercial enterprise merely because it has been deemed not to adhere to the prevailing body of scientific opinion - whatever they have determined that to be.
Re-creative artists are investigators.
In a lifetime among cops since, I've noted that investigators who piece together the aftermaths of home invasion murders tend to keep their guns on all the time after that, even when off duty in their own house, and keep them by the bed when they go to sleep. They have learned from the helplessly-murdered dead
Prior to the PATRIOT Act, the ability of government agencies to share information with each other was limited, which kept investigators from fully understanding what terrorists might be planning and to prevent their attacks.
I am myself by inclination an investigator.
My parents are private investigators for God's sake.
If baseball wants to get you, they've got enough resources and enough investigators that they'll find a way to get you.
Human experience, which is constantly contradicting theory, is the great test of truth. A system, built upon the discoveries of a great many minds, is always of more strength, than what is produced by the mere workings of any one mind, which, of itself, can do very little. There is not so poor a book in the world that would not be a prodigious effort were it wrought out entirely by a single mind, without the aid of prior investigators.
The fact that knowledge endlessly recedes as the investigator is about to grasp it is what constitutes at the same time his torment and happiness.
The plot is very important because writers have to play fair with their readers, but no one would care about the plot if the character work wasn't there. So, basically every book I work on starts with me thinking not just about the bad thing that's going to happen, but how that bad thing is going to ripple through the community, the family of the victim, and the lives of the investigators. I am keenly aware when I'm working that the crimes I am writing about have happened to real people. I take that very seriously.
