Architect Wren Fontaine is renovating Cadieux House, a modernist masterpiece. The home's original architect was the brilliant Marius Cadieux, and it comes with a dark past: In 1955, it was the site of the never-solved murder of its owner, Dennis Blaine. Was Cadieux having an affair with Dennis's stunning wife? It's yesterday's news, but then another murder happens at the mansion. Wren soon finds that only the home's odd curves and strange angles contain the truth.
