«El testigo invisible» is a book of crime stories by Wolfgang Ecke, published by Altea Junior in paperback (137 pages, in Spanish).
Twenty brief mystery cases pose an enigma to the reader. Each case has its solution at the end of the book, but it is advisable to look first for the clues hidden in the narrative and in the illustrations. The cases are organised into three levels of difficulty: some are solved by any reader, while others demand greater attention and experience.
The book belongs to the Altea Junior Enigmas collection (number 17) and is the eighth instalment of the Club der Detektive series; its original title is Der unsichtbare Zeuge.
Aimed at child and young readers who enjoy deduction challenges and solving enigmas.
