There are two boys in the photograph.



One of them is Leo.



He has never seen the other one before.



On the back, someone has written:



LEO + JONAS – SUMMER 2025



When Leo asks his parents, their answer is immediate.



You don't have a brother. You never did.



Then Krümel starts scratching at a wall.



Behind it, Leo and his friends discover a hidden door—and a bedroom that should not exist. A bed. Books. Clothes. Photographs. Recordings.



And everywhere, the same name:



Jonas Martin.



The deeper Leo, Mina, Ruby, Ben, Noah, and Eleanor follow the traces of the missing boy, the more impossible the truth becomes.



Jonas was not a stranger.



He was Leo's older brother.



And someone—or something—rewrote the world as if he had never existed.



But Jonas is not simply gone. Somewhere beneath Bellwick's reality lies another layer filled with lost memories, abandoned possibilities, and lives the world chose to forget.



To bring his brother home, Leo must finally discover what 00:13 really is.



And why Jonas may be the only thing keeping Bellwick from tearing itself apart.



Memories can disappear. People can be forgotten. But what happens when reality itself decides who was ever allowed to exist?



00:13 – The Brother Who Never Existed is the emotional, suspenseful finale of Heinz Siegfried Pestner's Bellwick trilogy—a mystery adventure about family, friendship, memory, identity, and the things that should never be lost.



Born in 1970, Heinz always wanted to make films. But in the 1980s in Graz (Austria), this wish could not be fulfilled.



So he learned a "regular" job as a media salesman. But he did not give up his passion for photography, filming, making music and writing.



"Better late than never", he says and now his first book has been published! A film about the book is in production and he also released two songs for it (@Heinz Siegfried) at the same time.



This proves it once again - everything is possible if you believe in it!
