Prepare for rodent mayhem in the first book of this laugh-out-loud new series from Ben Davis, with rib-tickling illustrations from James Lancett!

Lenny Lemmon is looking forward to 'Olden Days Day' at school. It’s a chance to break the routine and try school as it was years ago. It explains the blackboard in the corner, his teacher’s bad temper and why his friend Sam looks like Oliver Twist.

And Lenny’s pleased with his own contribution, too. It’s in a cardboard box at the back of the class at the moment because it’s not yet time to shine. Except it escapes and ends up in the bowl of gruel, that Amelia Kelly has brought in...

Soon there are small, gruelly footprints all over the classroom and also a lot of screaming because the RAT that Lenny found by the back of the chip shop is FREE!

Can Lenny round up the rat before more damage is done? Or will he end up in the headmaster’s office – again.

A hilarious school-based comedy for 7+ with black and white illustrations throughout. A modern day Just William!
