They raised her. Nurtured her. And lied about everything.

They told Sadie she was adopted.

They gave her a home and showered her with love.

But they lied.

While in Paris, Harvard symbologist Robert Langdon is awakened by a phone call in the dead of the night. The elderly curator of the Louvre has been murdered inside the museum, his body covered in baffling symbols. As Langdon and gifted French cryptologist Sophie Neveu sort through the bizarre riddles, they are stunned to discover a trail of clues hidden in the works of Leonardo da Vinci—clues visible for all to see and yet ingeniously disguised by the painter.

Even more startling, the late curator was involved in the Priory of Sion, a secret society whose members included Sir Isaac Newton, Victor Hugo, and Da Vinci, and he guarded a breathtaking historical secret. Unless Langdon and Neveu can decipher the labyrinthine puzzle—while avoiding the faceless adversary who shadows their every move—the explosive, ancient truth will be lost forever.

When an Irish orphan comes to live as an au pair on Long Island, she encounters a deadly mystery-and will need the help of her sleuthing aunt Claire. One of the first things Claire Breslinsky loved about Johnny was that he never even glanced at her sister. Carmela had always been the glamorous one, but Johnny only had eyes for Claire-the frazzled, world-traveling photographer who solved mysteries in her spare time. Only when their marriage fell apart did Claire learn that Johnny avoided Carmela because they'd had a clandestine fling in high school. When Carmela discovered she was pregnant, she fled to Ireland, where she left her daughter to be raised by her eccentric spinster aunts. Now Johnny is gone forever-but Claire's niece is coming home. Jenny Rose Cashin arrives from Ireland to take a job as an au pair in a fading Long Island resort town, hoping to reconnect with her long-lost mother. But something evil lurks in the quiet beachside residences of Sea Cliff. There is a killer on the grounds of this strange art colony, and Jenny Rose will need all the help she can get from her aunt Claire to uncover the truth-and stay alive.
