A series of bloody murders in Hong Kong, Geneva, Oslo, New York and Tel Aviv of people not associated with the Vatican, a conspiracy against the Pope - just links in one chain. A mysterious manuscript in Aramaic discovered in the Egyptian desert, mysterious Varangian runes on a sculpture of a lion in Venice, a tombstone on a 13th-century Christian grave with an inscription in Arabic are just pieces of a puzzle, solving which you can find the way to the mysterious Water Labyrinth and reveal the secrets that connect the first centuries of Christianity with the present day. Which is stronger - a bullet or word? A bullet can pierce a body, making it lifeless, but a single word can kill a person’s soul and doom him to a life of torment. And is a secret that they want to keep at any cost really so important?
