Cal Donovan is back in Rome during Christmas holidays from his teaching job at Harvard. He's enjoying his special privilege of unlimited access to the Vatican Library and Archives, researching for his next paper. As he's deeply engaged in a document, he comes across an interesting letter and follows its trail. It seems that in 1848 when the Papal States were under attack by revolutionaries, the Vatican borrowed a very large sum of money from the Sassoon Bank. The terms and circumstances all sound a bit shady. Cal continues to research this event but cannot find any evidence that the loan was ever paid back.

Knowing that Pope Celestine VI is concerned with the current financial situation of the Vatican, and Catholic Church in general, Cal pays him a visit. Yes, Cal has that special privilege too, as he and the Pope have developed a very special friendship. Pope Celestine is extremely concerned about this debt, and the mysterious occurrences surrounding it; so, he asks Cal to further research this loan. That research takes Cal back to New York City and almost gets him killed. Bodies are dropping all around him. Can he get to the bottom of this debt for the Pope and stay alive to return to Boston and his safe teaching job at Harvard?

THE DEBT is Glenn Cooper's third book in his A Cal Donovan Thriller series. Cal is a delightful, self- motivated character with many talents and interests. THE DEBT is a fast-paced religious conspiracy thriller that will have you on the edge of your seat and keep you there. Mr. Cooper employs the use of intermittent flashbacks to tell the back story of the ancient loan and the events that surrounded its origin and history. There is plenty of suspense, globe-trotting, blackmail, sabotage and even a little splash of romance in this dynamic thriller. You'll meet new characters, get reacquainted with old ones and learn some important lessons about the true business of the church ... altruism. This book can be read as a stand-alone, but you really don't want to miss the others in this series.
