One day, while at a used bookstore I came across a book with the following plot:
The main character lives an extra-ordinary life. He is a WW2 hero and spy. He comes home from war and is elected to Congress. He winds up serving several presidents in different cabinet posts. He caps off his public service career by being appointed to the be Chief Justice of the United States Supreme Court. When his wife, the love of his life, dies, he retires from the Supreme Court and enters the priesthood. The pope dies in the middle of an international crisis that affects the Church. In the conclave, the cardinals looking for a pope who can deal with the situation elect him to be Pope turn to the main character.
I read the jacket. Didn't have enough money so I'd buy it on the next trip. Came back and the book is gone and I didn't write down the title (I thought it was so easy that I would remember it).
Anyone know the name and author of a book with such a plot?
