Have you ever wondered where the other sock goes, or those keys or your earring or pen? Grandad wonders that all the time.

Things keep disappearing down the back of Grandad's sofa - so who, or what, has taken them?

When Lenny and Grandad discover the Kleptoes and their hideout, things turn nasty. And Kleptoes can be very nasty indeed ... especially Old Mother Kleptoe.
