The Book of Lies by Brad Meltzer

In chapter four of the Bible, Cain kills Abel. But it never tells what kind of weapon Cain used to kill Abel. In 1932, Mitchell Siegel was killed by two gunshots to the chest. Because of this his creates Superman. Today in Fort Lauderdale, FL, Cal Harper comes face-to-face with his own family tragedy. So begins the search for the first murder weapon. This book started a little slow, but it really got rolling, and I really enjoyed after that. I couldn't put it down. PatM
