For Commissioner Daria Vinci, it was supposed to a night off, attending a benefit concert for the Institute of America in Rome. But little did the wealthy, distinguished guests know that beneath their feet, in the ancient catacombs, a very different kind of gathering was being held. One that would end in murder. In Roman Roulette , the second Daria Vinci investigation, the glamorous and high-principled investigator must investigate what at first seems a simple case of suicide. Pushing for a full account of that underground meeting, she attracts the attention of her old boss and nemesis, Questor Carlo Centauri, who has his own reasons for wanting her off the case. Now, Daria Vinci must solve the murder in 36 hours, while risking her career and, possibly, her life.
