Who shot Brother Semyon Ivanivich Popov? There were only four professors in the building on the night of the shooting: a feminist theologian, a distinguished scripture scholar, an expert on the Talmud, and a young tenure-seeking professor whom Blackie compares to a silverback gorilla. It turns out that the mystery of the locked room is simple compared to the international intrigue that swiftly develops around the case. Intelligence agents from diverse nations seem to be involved, as well as both the Sicilian and Russian mobs. Blackie soon finds himself the target of threats and actual bullets as he seeks to unravel the deepening mystery surrounding the murdered monk-whose murky secrets may stretch all the way to the Vatican itself!
