Being a Roman Catholic, this book caught my eye because it promised to address to interesting topics: Papal Infallibility and the Church's stance on birth control. The latter is a particularly relevant topic these days because the question has been raised as to whether the state can require the Church to pay for birth control as part of health insurance.Yes, the book did address these topics, and it intertwined them with a murder mystery story. I give credit to the author for attempting that combination. However I was ultimately displeased with his characters and their stories -- it was just too implausible and unpalatable.
