Publisher's Synopsis
When one dark night in November, Prince Ludovico Ruspanti fell a hundred and fifty feet to his death in the Basilica at St. Peter's, Rome, there were a number of questions to be answered. What was he doing in the Vatican? Why was he being watched? Did he fall? Or was he pushed? The papal authorities contacted the Criminalpol; the duty officer put out a call. Inspector Aurelio Zen is back on duty. As Zen probes deeper into Ruspanti's death, he finds witness after witness mysteriously silenced by death. He soon understands that he will never crack the case until he has penetrated the most secret of all secret societies - the Cabal.
