A grieving young widow, seeking answers to her husband's death, becomes entangled in an investigation steeped in the darkest mysteries of Rome.
Sandra Vega, a forensic analyst with the Roman police department, mourns deeply for a marriage that ended too soon. A few months ago, in the dead of night, her husband, an up-and-coming journalist, plunged to his death at the top of a high-rise construction site. The police ruled it an accident. Sanda is convinced it was anything but.
Launching her own inquiries, Sanda finds herself on a dangerous trail, working the same case that she is convinced led to her husband's murder. An investigation which is deeply entwined with a series of disappearances that has swept the city, and brings Sandra ever closer to a centuries-old secret society that will do anything to stay in the shadows.
