In the Haereticum - the Vatican’s secret library of blasphemy - there is an ancient book known only as The Veritas. Throughout history, anyone who has ever read it has immediately taken their own life. Now a new translation is online, and the danger is spreading. The Vatican appeals to the Doctor. Will he read The Veritas? But can even the Doctor survive the ultimate truth?
