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 third book in the series sees Mortimer Keene up to no good again with an alien ray gun machine!

When the school is invaded by aliens and Mr Bevan the English teacher is abducted, everyone suspects the young genius Mortimer Keene!
