[3] It tells the story of Sune Andersson during the spring term of the 1st grade at school in Sweden.

Sune is a so-called tjejtjusare ("girl charmer"), but mostly he likes Sophie in the same class at school.

One Friday when walking to school, Sune gets "Goddag, goddag-sjukan", a disease where the affected can only say "God dag, god dag" ("Good day, good day"), even if the disease always comes to an end later.

Sune is about to free Daniel, but ends up in trouble with 3rd grader Bengt, who chases him until he is saved by the bell.

Sune kicks the ball, which crashes into the apartment of a man called "Gäckande skuggan".

Sophie is not afraid and goes with Sune, and it soon turns out there is no "Gäckande skuggan", just Alvin Hjalmar Edwin Gren who is not dangerous at all.

He tells about his seaman life, and about being thrown into prison in Tunis after fighting with a Greek over a girl, and that it was his wife and children who left him.
