The Wolfman‘s Emily Blunt, pictured above, is attached to star in the psychological thriller Sister, which Kevin McCormick (Gangster Squad) is developing under his Langley Park banner, TheWrap has learned.

StudioCanal is financing development of the project, which is based on Rosamund Lupton’s bestselling novel “Sister.” The project is near and dear to Blunt, whose own sister, literary agent Felicity Blunt, represents the book, which has sold more than one million copies worldwide.

The London-based mystery follows Beatrice (Blunt) as she investigates the death of her younger sister Tess, whose death is ruled a suicide by police. Convinced that her sister was murdered, Beatrice sets out to uncover the strange events leading up to Tess’ death, though she may pay a terrible price for the truth.

Rory Koslow will oversee the project for Langley Park, which is currently searching for a writer to adapt Lupton’s novel.
