The Ghost in the Library is a stand-alone title with longer text, in the exciting and scary "Mysterious School" series.
Greta loves her school. Mysterious things happen here, things not always visible to the naked eye…
Today their librarian, Amir, is very angry. Someone has used the library’s ladder, taken down a valuable black book, and then left it lying of the sofa. It is absolutely forbidden!
The next morning when Greta and Malte meet on the playground, they notice that a lamp is lit in the library and that a dark shadow looms behind the curtain. Who could it be? Might it have something to do with the precious old black book?
