The hero of the book is little Frankie Lightening, who doesn’t like Brussels sprouts, but loves puzzles, even crime mysteries. Fortunately, he has a lot of opportunities to put himself to the test, because in his neighbourhood strange things often happen. So Frankie has to figure out where the glass egg found in the excavations came from, who the sixth pineapple is, who stole the tires of Horace’s tractor and where the brooch, which is not a brooch, has gone – and these are not the only unusual things that he has to deal with. The good preschooler is helped out by his mother, as well as neighbours and strangers who also get involved. The book should appeal to children because of a main character they can relate to, interesting, sensational action combined with solving puzzles. The boy’s adventures are accompanied by beautiful full-colour illustrations that help build up the mood of the book.
