Book excerpt: The Law of Falling Bodies A professor is murdered. An eyewitness sees the whole thing. The only suspect confesses. So, what's the problem? It is physically impossible for the suspect to have committed the murder that way! To unravel this mystery, it will take a nave young scientist who is no one's idea of a hero. Sure, Mark is a wizard at solving puzzles, but he hardly knows one end of a gun from the other. At first, the murder is an enticing riddle, with the added spice of a beautiful but single-minded police detective. But soon he'll have to face a belligerent FBI agent with his own ideas about right and wrong, not to mention a shadowy killer who'll stop at nothing to eliminate him. Mark may have a lot to learn about life, but he already knows enough about... The Law of Falling Bodies Love and hate. Life and death. Math and physics.
