There are hidden clues everywhere in this riotous, pacy picture book about a little boy's suspicion that his sweet, elderly neighbour is secretly keeping an array of dinosaurs in her house.

The boy tries to alert his parents to the presence of claws, jaws and prehistoric roars coming from next door, but they remain blithely unconcerned. Mrs Shaw from Number 84 does NOT have any dinosaurs, of that they're sure . . .
