The ink is still wet on the contract, but Wren Fontaine is already running into trouble as she renovates Cadieux House, a modernist masterpiece on Long Island's exclusive Gold Coast. The home's architect was the brilliant and eccentric Marius Cadieux, her father's mentor, and Ezra doesn't want Wren to change as much as a doorknob.

And the home itself comes with a dark past: In 1955, it was the site of the never-solved murder of its owner, Dennis Blaine. Cadieux himself was alleged to be having an affair with Dennis's wife, the stunningly beautiful Rebecca. It seems like yesterday's headlines, but then someone starts killing people with a connection to the house. The home's new owner-bestselling novelist Bronwyn Merrick-may be using the house to launch a fictionalized account of the 1955 crime. But someone may not want to her to. Just how far will Bronwyn's armed bodyguard go to protect her?

As Wren untangles the threads, she finds they all lead back to the house. Rebecca apparently inspired the strange, yet alluring residence, and both the home and its mistress may have caused uncontrolled emotions that led to tragedy. Wren uses all her architectural skills to decipher the hidden message Cadieux cunningly wove into the home's design. She must think back 20 years to when, as a little girl, she met Cadieux. Deeply impressed with Wren, he gave her a clue about the house-and his unusual friendship with Rebecca. With her girlfriend Hadley at her side, Wren eventually solves the mysteries of the home and the people who lived there, develops a grudging respect for modernist architecture-and learns something about the difference between love and obsession.
