The Rollercoaster Case by Sally Gardener

'Agatha Christie for kids' - the third in a detective agency series brimming with mystery and magic by million-copy-selling author, Sally Gardner, and illustrated by acclaimed artist, David Roberts.

The famous detective agency, Wings & Co, has a problem. Really quite a big problem. Well, a few of them actually.

There's the missing giant, Billy Buckle, who has vanished without a trace, and left his giant daughter with the detectives. There's a surprise visit to the seaside, which uncovers a murder and a stolen diamond. And then there's that tricky business of the TV talent show.

Squat on a squid, this is Emily, Buster and Fidget's most complicated case yet!

Includes Wings and Co detective case notes, character profiles and clues.
