In 1649, a group of friends went into the forest of Monblanc and encountered a killer known as "The Killer of the Cake". He kidnapped the friends and said he would torture them if they did not make him a chocolate cake within two hours. The boys made the cake as a diversion and managed to kill the murderer. They then escaped the forest, eating the chocolate cake along the way. However, the killer ultimately followed them home. The document also includes the recipe for the chocolate cake.
