Alex Cross is a homicide detective with a Ph.D. in psychology. He works and lives in Southeast D.C. and looks like Muhammad Ali in his prime. He's a tough guy from a tough part of town who wears Harris Tweed jackets and likes to relax by banging out Gershwin tunes on his baby grand piano. But he also has two adorable kids of his own, and they are his own special vulnerabilities.

NYPD Detective Michael Bennett is about to take on the most sinister challenge of his career. The nation has fallen into mourning after the unexpected death of a beloved former first lady, and the most powerful people in the world gather in New York for her funeral. Then the inconceivable occurs. Billionaires, politicians, and superstars of every kind are suddenly trapped within one man's brilliant and cold-blooded scenario.

A wealthy businessman approaches Jack Morgan, head of Private—the world's largest investigation agency—with a desperate plea to track down his daughter and grandchildren, who have disappeared without a trace. What at first seems to be a simple missing persons case soon escalates into something much more deadly, when Jack discovers the daughter is being pursued by highly trained operatives. As Jack uncovers more of the woman's backstory, the trail leads towards Afghanistan—where Jack's career as a US Marine ended in catastrophe.

Since former Marine Jack Morgan started Private, it has become the world's most effective investigation firm--sought out by the famous and the powerful to discreetly handle their most intimate problems. Private's investigators are the smartest, the fastest, and the most technologically advanced in the world--and they always uncover the truth.

Known as the Women's Murder Club, they are pursuing a murderer whose twisted imagination has stunned an entire city. Their chief suspect is a socially prominent writer, but the men in charge won't touch him. On the trail of the most terrifying and unexpected killer ever, they discover a shocking surprise.
