A wickedly funny series that will appeal to all young scientists, created by Chris Mould, illustrator of A Boy Called Christmas and Tim Healey. If you like Horrid Henry, you'll love Mortimer Keene.

Mortimer Keene is full to bursting with madcap plans, and if it's trouble you're after, look no further! With laugh out loud illustrations, rollicking rhymes, and short chapters perfect for new readers, this second book in the series sees Mortimer Keene and his phantom machine up to no good again!

When the school is overrun with ghosts and ghouls from the past, it's up to Mortimer Keene to blast them back in time and save the school.
