Watching a suspect, securing clues and following up valuable leads - what child doesn't dream of being a detective themselves one day and solving a criminal case? That's exactly what happens to Lena, Willi, Konrad and Tina. The two pairs of siblings with the almost identical last names Hermann and Herrmann discover a young trickster disguised as a fundraiser stealing from unsuspecting passers-by. As the detective club HeRRmanns, they investigate the case.

The "Sundays in the Library" project is funded by the state of NRW as part of the program to strengthen Sunday opening in libraries (ProSiB).
