When postmen and policemen start to go missing, monster agents Nelly Rapp and Valle are called in to solve the mystery. The two agents and friends happen to be experts at tackling monsters and other dangerous critters with a little help from the three guiding C’s: calm, cleverness and cunning. In this new adventure, their skills are put to the test more than ever, as they have to solve the riddle of why people, ever since the middle of the 1800s, have disappeared without a trace when they visit the creaky old house in the woods (and why so much furniture has piled up inside over the years…).

Nelly Rapp and the Witch is the twenty-first standalone book in the series about Nelly Rapp, and the second book with fantastic illustrations by Emil Maxén.
