A violent prison riot breaks out during the class, and in the chaos, Nat rushes to help a grievously injured prison guard. Before he dies, he asks her to deliver a cryptic message with his last words: "Tell my wife it's under the floor."

The dying declaration plunges Nat into a nightmare. Suddenly, the girl who has always followed the letter of the law finds herself suspected of a brutal murder and encounters threats to her life around every curve. Now not only are the cops after her, but ruthless killers are desperate to keep her from exposing their secret. In the meantime, she gets dangerously close to Angus, whose warmth, strength, and ponytail shake her dedication to her safe boyfriend.

With her love life in jeopardy, her career in the balance, and her life on the line, Nat must rely on her resources, her intelligence, and her courage. Forced into hiding to stay alive, she sets out to save herself by deciphering the puzzle behind the dead guard's last words . . . and learns the secret to the greatest puzzle of all—herself.

Filled with the ingenious twists, pulse-pounding narrative drive, and dynamic, flesh-and-blood characters that are the hallmarks of her bestsellers, Daddy's Girl is another wild, entertaining ride about love, family, and justice from the addictively readable Lisa Scottoline.
