Doctor Proctor's Fart Powder

by Jo Nesbo

Published 29 December 2009
Dr Proctor is an ageing inventor just waiting for his big break. And when he teams up with his next-door neighbour Lise and her peculiar friend Nilli in making the world's most powerful fart powder, it seems his dream may be coming true. But the ruthless twins Truls and Trym Thrane are lurking in the background just waiting to spoil their plans. The drama that follows has repercussions that stretch beyond the imagination, inolving a wild chase through the sewer system of Oslo, anacondas and NASA. Full of humour and witty dialogue, Jo Nesbo creates wonderfully weird characters and lets his imagination run wild in this delightful children's book debut, reminiscent of Roald Dahl.

Can Doctor Proctor Save Christmas?

by Jo Nesbo

Published 2 November 2017
Can Doctor Proctor, Nilly, and Lisa save Christmas in this new fart-tastically funny adventure from worldwide bestselling author Jo Nesbø?

When the king of Norway sells the rights to Christmas to Mr Thrane, it looks like the holidays aren’t going to be very merry. Mr Thrane says that the only people who can celebrate are those who buy 10,000 crowns worth of presents from his department store. For anyone who doesn’t - or can’t - spend that much, it’s no tree, no presents, no carols, and no Christmas pudding.

​Doctor Proctor, Nilly, and Lisa aren’t going to take this sitting down! They’re going to find Santa and save Christmas. All they need is a sleigh, flying reindeer, some time travel soap, and, of course, some fart powder!
