About the book: 2013 / Meet Jo Nesbø, a Norwegian author of detective stories that are read by adults all over the world. And this is the first in a series of books for children written by Jo Nesbø, a Norwegian author of detective stories that are read by adults all over the world. And this is Dr. Proctor, a crazy (in a good way) professor, around whose inventions crazy (in a good way) events develop in children's books written by Jo Nesbø , a Norwegian author of detective stories that are read by adults all over the world. And this is Lise, a girl from Cannon Street in Oslo, the owner of short braids and a neighbor of Dr. Proctor, around whose inventions... well, you understand. And this is Bulle, Lise’s new friend, and also , probably the smallest, reddest, fastest and most cheerful boy on our planet. And this is Dr. Proctor’s new invention, which Bulle volunteered to test on himself: magic powder. For the first time in Russian!
