But a week before the opening of the exhibition, its curator, an outstanding scientist, dies at the hands of an unknown killer, and suspicion falls on his friend and assistant, a Roman Catholic priest. And now, in order to acquit an innocent man, it is necessary to unravel the mystery of priceless Christian relics - a mystery that goes back thousands of years. A new world bestseller from the author of “The Rule of Four”! For the first time in Russian!
