“What does basketball have to do with finding a murderer?” 

This question was posed by Merlot Candy, a private investigator, to Dennis Cane, a police detective in one of the chapters of “A Moving Screen.” The answer is great: “The investigator sets a screen between the intended victim and the killer.  The investigator has to move or the killer will never be caught.”

In basketball A Moving Screen is a foul. In a homicide investigation  A Moving Screen is good police work.
