Richard Byrne: Primer tatu, rdečega od prahu

Someone is stealing the chalks’ lovely drawings. But he leaves some dust at the scene of the crime and only one suspect has a dusty red bottom! Sergeant Blue is quick to solve the investigation and bring the case to a happy conclusion for all!

With a bold graphic look on a chalkboard-black background, this is a fun story where readers truly participate in the investigation: looking for the clues, assessing the line-up of suspects, and closing in on the culprit.
