An story that plunges into the complicated nooks of the human mind and explores the soul of a murderer.


Sometimes life can be twisted in such a way that it seems that we are living a nightmare that does not correspond to us.

Upon arrival at his tourist destination, an intelligent but naive young man who loves role-playing games and is passionate about numbers and mathematics will be caught in a dark plot. The mystery begins five years before with a murder whose author will manipulate the crime scene by making it look like a macabre work of art that no one understands. The criminal looks to share his same passion for numbers and will leave behind a strange biblical symbol hidden for centuries by the Vatican.

Only he could be able to solve the puzzle, but he will not have it easy. A courageous mother will help him on a journey full of unusual elements that seem beyond reality, places that hide great secrets, symbols full of meaning and harsh judicial investigations. Without realizing that she might discover something more disturbing: that her son was not what she thought.
