Doctor Proctor has invented "The Fart Powder" - a powder which can make you fart the most tremendous fart you ever saw and better still – with no smell! With some help from Nilly the tiny boy from next door, and Lisa whose best friend just moved to Sarpsborg, Doctor Proctor hopes to become a famous inventor. But the twins, Truls, and Trym, are out to steal the Fart Powder.

Will Doctor Proctor finally get the recognition he deserves and will Lisa find a new best friend?

Oh yes, and what's that anaconda doing in the sewers…

You will find out the answers to these questions in Doctor Proctor's Fart Powder - a hilariously funny, totally crazy, and exceptionally brilliant book. Five laughs a page, brilliantly set, with some fantastic characters. And I can't wait for the next book by Jo Nesbo, the most explosive one yet!
