You'll find this in your detective story:

 
 Lots of exciting questions to solve: Let your children step into the shoes of detectives Pete and Max. They can guess along and help solve the case.
 
 Detective foil: With our red detective foil, your children will get on the trail of every solution.
 
 Charming color illustrations: facilitate understanding of the English text and bring the story to life.
 
 Vocabulary boxes on each double page explain particularly difficult vocabulary and idioms. This vocabulary also appears at the end of the book in an alphabetically ordered glossary. The glossaries in the individual volumes build upon one another.
 
 Text length tailored to learning level: Volumes 1 and 2 contain short sentences with simple vocabulary and are therefore particularly suitable for primary school students. Volumes 3 and 4 are increasingly used in the first two years of secondary school.
