As the Roman Catholic Church prepares for Thursday’s funeral of Pope Emeritus Benedict the XVI a new book is promising to shine a light on papal secrets.

Benedict’s longtime personal secretary has written a tell-all book that the publisher promises will focus on the “dark maneuvers,” mysteries and scandals that sullied Benedict’s reputation.

The book is titled “Nothing but the Truth: My Life Beside Pope Benedict,” authored by George Gaenswein, a 66-year-old German priest, who stood by Benedict’s side for nearly 30-years.

The book contends that anyone who thinks there can be a calm papacy has got the wrong profession.
