Deep in the muddy trunk laid a suitcase they both recognized. "Ladies first," Johan waved Klara elegantly into the car. Klara smiled and climbed in. She opened the suitcase ceremoniously. There it was, in all its glory, Munch's Scream. Klara turned around to say something to Johan, but the words were stuck in her throat. Johan wasn't alone."
Klara and Johan witness a theft when their school class visits the Munch Museum, and all alone, they have to hunt for the thieves and the painting. A dangerous chase leads them close to the syndicate Sorero Mortis. Strangely, the chase also leads the readers back to the Second World War, and the world's largest ship disaster, where thousands of innocent people lost their lives at the end of World War II; the sinking of Wilhelm Gustloff.
