Brad Meltzer — author of the #1 New York Times bestseller The Book of Fate — returns with his most thrilling and emotionally powerful novel to date.

In Chapter Four of the Bible, Cain kills Abel. It is the world's most famous murder. But the Bible is silent about one key detail: the weapon Cain used to kill his brother. That weapon is still lost to history.

In 1932, Mitchell Siegel was killed by three gunshots to his chest. While mourning, his son dreamed of a bulletproof man and created the world's greatest hero: Superman. And like Cain's murder weapon, the gun used in this unsolved murder has never been found.

Until now.

Today in Fort Lauderdale, Florida, Cal Harper comes face-to-face with his family's greatest secret: his long-lost father, who's been shot with a gun that traces back to Mitchell Siegel's 1932 murder. But before Cal can ask a single question, he and his father are attacked by a ruthless killer tattooed with the ancient markings of Cain. And so begins the chase for the world's first murder weapon.

What does Cain, history's greatest villain, have to do with Superman, the world's greatest hero? And what do two murders, committed thousands of years apart, have in common? This is the mystery at the heart of Brad Meltzer's riveting and utterly intriguing new thriller.

Brad Meltzer is the #1 New York Times bestselling author of The Book of Fate, as well as the bestsellers The Tenth Justice, Dead Even, The First Counsel, The Millionaires and The Zero Game. He is also one of the co-creators of the TV show, Jack & Bobby—and is the number one selling author of the critically acclaimed comic books, Identity Crisis and Justice League of America. His newest comic book, DC Universe, will be released in August, and his new thriller, The Book of Lies, will be published in September.

Raised in Brooklyn and Miami, Brad is a graduate of the University of Michigan and Columbia Law School. The Tenth Justice was his first published work and became an instant New York Times bestseller. Dead Even followed a year later and also hit the New York Times bestseller list, as have all six of his novels. The First Counsel came next, which was about a White House lawyer dating the President's daughter, then The Millionaires, which was about two brothers who steal money and go on the run. The Zero Game is about two Congressional staffers who are—literally—gambling on Congress. The Book of Fate, is about a young presidential aide, a crazed assassin, and the 200 year-old code created by Thomas Jefferson that ties them together. For authenticity, The Book of Fate was researched with the help of former Presidents Clinton and Bush. His newest book, The Book of Lies, is about the missing murder weapon that Cain used to kill Abel, as well as the unsolved murder of Superman creator Jerry Siegel's father. Brad is one of the only people to interview Jerry Siegel's family about the murder.

His books have spent over nine months on the bestseller lists, and have been translated into over 25 languages, from Hebrew to Bulgarian. In The Tenth Justice, the opening lines are: "Ben Addison was sweating. Like a pig." In the Hebrew translation, it became: "Ben Addison was sweating. Like a horse." We're not sure if it's a kosher thing or what!

Brad has played himself as an extra in Woody Allen's Celebrity and earned credit from Columbia Law School for writing his first book, which became The Tenth Justice. Before all of that, he got 24 rejection letters for his true first novel, which still sits on his shelf, published by Kinko's.

Brad currently lives in Florida with his wife, who's also an attorney.
