"It must have been May 1917. You were one of the many orphans the Great War made, in Louvain, Aarschot, Dinant. I don’t know what exactly happened with doctor Scharpeneel’s happy family. But suddenly his wife was dead, he was badly wounded and where was his little girl Isabelle?""Doctor Scharpeneel recovers from his injuries and goes looking for his daughter Isabelle. In Hotel Ocean in De Panne lives one of the orphans the Great War made. Belgian soldiers adopted the girl and gave her a name: Jeannette Elisabeth Shrapnel.""They promised you that at least one of them would come back to be your father, they made a photo for a postcard… I had your photo in my pocket when I marched to the Hell Fire Corner.""The year is 1936. There’s an article in the newspaper about the secret victims of the Great War, tucked away in the Franz Jozef Hospital, Vienna. What they have in Vienna, they may have in other places, too… And again I go searching for my secret playmate, my invisible friend, my Unknown Soldier."
